Red Alert helps staff feel more secure knowing that in an emergency they can summon assistance at the touch of a button on their personal transmitter.

What is Red Alert?

Red Alert is a system that has been designed to give staff the flexibility to remotely activate an alarm using an infra-red transmitter. Commonly used by medical staff as a personal attack alarm system as well as a medical emergency alarm system.

What happens when I need assistance?

Any member of staff carrying an alarm transmitter can simply press the alarm button. This will send out an infra-red signal that floods the room with its particular coded light. In more urgent cases it may be easier to pull the transmitter from the clothing clip and throw it to the floor. It is sturdy enough to withstand this and will carry on transmitting.

What happens then?

When the receiver senses the coded signal it relays the information back to the control unit (Hub). The Hub, seeing that a call has been made, instantly identifies the exact location and then transmits that information back out to the system. It can send the information to indicator panels or via radio signals, to pocket pagers carried by key personnel. The location of the call is displayed on the indicator panels and pagers.

What text can be displayed?

Any text you want up to 20 characters! The exact location of the call is sent for example, ‘consulting room’, along with the level of urgency (there are 4 levels available). This text can be changed at any time by using the hand held programming unit.

Is it a well proven system?

Yes! We have been designing, manufacturing, installing and servicing electronic systems for over 35 years. The Red Alert Personal Attack system was added to our product range several years ago. It has been installed to great acclaim in hundreds of establishments throughout the UK and also internationally. It has a proven record of reliability that has been specified by many UK NHS Trusts and Health Boards.

Are there any other facilities?

There are many other features and facilities that the system can offer. One major example is that the system can be integrated with our range of nurse call equipment. This provides a cost effective solution for a centralised personal attack system for the staff to use with a fully featured nurse call system for the care of the patients.

What size systems can be installed?

The system is extremely flexible. One hub will support up to 254 addressable points and 26 displays with no extra power supplies or boosters. Larger systems are available by interlinking the hubs to provide whatever size scheme is required.

Who uses the system?

The system is used by a wide range of clients where their staff may be at risk of attack or abuse in the work place. Current users include over 150 NHS trusts in the UK. The trusts diversify from mental health, A&E departments, acute hospitals to EMI and general hospitals. Other users include doctors’ surgeries, schools, probation and bail hostels, local government particularly social services and housing departments. The system has been exported to Europe, the Middle East and Australasia.

Hub and power supply RED201

The HUB is the central control of the Red Alert system and has the ultimate capacity of 254 addressable call points and 26 LCD indicator panels. The cabinet has a lockable hinged door and houses the main control PCB (HUB), the power supply unit and has space for battery back up, if required. It should be installed centrally in the system layout, normally in a secure location and requires a 230v mains supply from an un-switched fused spur. An input from a day night volume control switch is available to adjust the volume of the LCD indicator panels; alternatively this can be set to automatically change at a certain time of day. A voltage free set of contacts is provided to trigger external devices in the event of a call, an alarm call or an attack call. These contacts can be used to trigger tone pagers or additional voltage sounder or strobe lights etc.


Battery back-up RED202

This is an option for buildings that may be particularly prone to mains failures. The standard rechargeable battery supplied has a 7Ah capacity. Larger back-up systems can be supplied and we can calculate the size of the battery from the required duration and the size of the system.

Infra-red programmer RED236

An essential tool during commissioning. It is used to programme the infra-red call points with their unique address number and the text description (room name) of the sensor. The information is entered into the programmer it is then pointed at the infra-red sensor, an infra-red link transfers the data. This makes changes of room names at a later date very easy.


Jack plug programmer NET236

It is used during commissioning to programme the non-infra-red addressable points i.e. RED245, RED210 and RED218 etc. with their unique address number and the text descriptions. The information is entered into the programmer it is then plugged in to the point via the jack socket. This transfers the programming information to the call point.

Designed to audibly and visually inform you of an alarm call. Choose the type best suited to the environment they are to be installed. The indicator panels with the larger style text display prove to be the popular choice. Check out the radio paging system in the Interface Equipment section, ideal for staff who are always on the move.

Indicator panel with large text display RED243

These indicator panels use the larger style 20 digit LCD modules, the two rows of text are displayed using illuminated 12mm high characters. Each indicator panel has an integral sounder and includes a mute switch to silence the call tone for a pre-determined period. The unit displays two calls simultaneously and, if more calls are made, the display can be scrolled to show each call in turn. Differing call tones let the staff know what level of alarm call has been initiated. A further button allows the installing engineer to adjust the settings of the display, these include day/night time volumes and mute delay. Another feature allows any of the control buttons to be isolated preventing misuse.


Flush mounting indicator panel with large text display RED248

Designed with the same features as our RED243 indicator panel with a high visibility larger style text display. This is the popular choice when the indicator panels may be subject to misuse. It is housed behind a white powder coated steel face plate for impact protection and a 4mm Lexan window to protect the display. It comes complete with a galvanised flush mounting back box.


Extension sounder RED212

This extension sounder is used to mimic the indicator panel call tones. They provide a cost effective way of providing an alarm sound in areas where indicator panels are not required. The tones generated are louder than those from the range of indicator panels.


These receivers are installed in the areas your staff may be at risk of attack. You also have the option of push button call points and reset points that allow you to connect in any type of alarm button you require.

Infra-red receiver RED205

These infra-red receivers are usually fitted in areas where the staff may feel at risk or may need to call for assistance. They receive alarm signals from our range of infra-red transmitters and send the location of the alarm call to the indicator panels. A red light reassures that an alarm call has been received and is also used in conjunction with our new alarm transmitter for the user test function (see RED208/5).


Infra-red slave receiver RED205C

This receiver is used to increase the coverage of an infra-red receiver. They are commonly used in corridors, large dining areas and en-suite wc’s. Up to three slaves can be connected to an infra-red receiver, which is sufficient to cover approximately 200 square metres. They are the same as the RED205 in appearance.


Externally mounted infra-red receiver RED255

This is a RED205 receiver mounted in a weather resistant IP65 rated enclosure. It is designed for use when personal attack coverage is required in external areas, for example gardens and patios. It has a range of approximately 10 metres and the alarm transmitters must be aimed towards the sensor and for this reason it has a bright fluorescent orange label.


Infra-red receiver with stainless steel face plate RED265

This receiver has the same features as a RED205 but it is manufactured with a stainless steel faceplate and a 4mm Lexan window to protect the infra-red sensor from abuse. It is recommended for areas where damage to standard sensors may occur. It is usually flush mounted but can be supplied with a surface-mounting box.

This slave receiver has the same features as a RED205C but it is manufactured with a stainless steel faceplate and a 4mm Lexan window to protect the sensor from abuse. It is recommended for areas where damage to standard sensors may occur. It is usually flush mounted but can be supplied with a surface-mounting box.


Push button call point RED245

A wall mounted call point with a large red actuator to activate an alarm call. These units are used in areas where staff or visitors may need to activate the alarm system but may not be carrying an infra-red transmitter. It is reset using a magnetic reset key (RED216).


Push button call point RED245M

This alarm call point is similar to the RED245 but is reset by the blue push button. A small red button is used to generate a higher priority attack call.


Reset unit RED204

A device designed to receive an input from an external alarm source for example, an alarm strip mounted on the underside of a desk or a hospital crash call system. Once activated it is reset using a magnetic key (RED216) meaning only authorised staff can cancel calls.


Reset unit RED204M

As the RED204 but with a blue reset button. Ideal when quick response to cancelling calls is required for example, when a door bell push button is connected.

Carried by staff who may be at risk of attack. Our new transmitter (RED208/6) is sure to be the popular choice with its enhanced range of features. Don’t forget the reset transmitter, needed to cancel any alarm calls.

Infra-red alarm transmitter RED208/6

Carried by staff in establishments where they may feel at risk of an attack or who might need to call for urgent assistance. An alarm button is used to unobtrusively activate an alarm call on the nearest infra-red sensor. Pulling the transmitter away from its clothing clip activates a higher priority attack call. Our latest alarm transmitter has been designed to include the features our clients requested. A button is provided to check the battery health, indicated by an LED array on the transmitter, furthermore the nearest infra-red sensors’ reassurance light will flash to confirm a healthy signal. This is a confidence inspiring feature for the user who can quickly test the transmitter and sensors’ function in an environment when dealing with a potentially serious situation. All transmitters have a serial number and the facility to personalise the label.


Infra-red reset transmitter RED209/6

This transmitter is used to cancel the alarm calls at their origin. This important feature means that all calls have to be dealt with by visiting the source of the activation. The person carrying this transmitter always has the option of pulling it away from its clothing clip and activating an urgent alarm call. The same function and battery tests are in-built as the alarm transmitter above for peace of mind.


Infra-red call transmitter NET208/1

A transmitter designed to be easy to operate. A large orange button activates an infra-red sensor with the lowest priority call level. It is ideal for use by residents or patients who are vulnerable and need the use of a call system. It can be supplied as a necklace pendant or as a hand held unit.


Magnetic staff key RED216

Carried by staff to enable them to reset alarm calls on call points with a magnetic reset facility (e.g. RED245 & RED204).

Over door indicator light RED210

A standard ODL can be programmed to respond to up to eight sequentially addressed devices. A Group ODL can respond to up to 96.


Indicator light with relay output RED210R

Similar to the over door indicator light, it can be activated by up to eight alarm points. The voltage free contacts provided can be used to activate other systems for example, to lock or unlock emergency exit doors, set off a strobe light or activate a nearby CCTV camera.


Stand-alone infra-red sensor RED200

It is similar in appearance to the RED205 sensor and has been designed to operate as a stand-alone sensor. This means that with a supply voltage (between 12 and 24 volt d.c.) to power it, any activation by a transmitter from our range will activate an on-board relay. These sensors are used to integrate with other call systems, providing them with the flexibility of infra-red technology.

Used to alarm fire exit doors, store rooms and controlled drugs cabinets.
This equipment gives you a cost effective monitoring system fully integrated with the Red Alert system.


Door monitor RED218

Located adjacent to doors or drug cabinets, these units generate an alarm call if the door is breached. A key switch is provided to isolate the door monitor when a door needs to be opened, the same key is used to reset following an activation. A red reassurance light shows its status. A timed override feature is provided to allow staff to exit a door without it activating. This can be done by a simple magnetic key swipe (see RED216 staff key) or if a higher level of security is required by a coded access keypad.


Over door light with sounder RED219

Used in conjunction with the door monitor, this indicator light can be fitted above a controlled door to indicate when an alarm call has been made. These over door lights are fitted with a sounder to attract attention audibly as well as visually.


A range of equipment designed to enhance the Red Alert system.
Seen by many clients as essential, the alphanumeric radio paging system allows mobile staff to receive alarm calls from anywhere within the building.


Alphanumeric pager transmitter RED228

An alphanumeric paging transmitter used in conjunction with the RED229 pocket pagers. The pager is used to send text messages to the response staff showing them the precise location where assistance is required. It can be configured in many different ways for example, allowing only the highest priority alarm calls to be paged or to link several Red Alert systems via a common paging system. It can also be configured to work as an on-site paging system with connections to a PC or telephone system. It is supplied with RS232 interface unit, connection lead and aerial.


Alphanumeric pocket pager RED229

Carried by response staff, these units can be programmed to bleep and vibrate, alerting staff that an alarm call has been received. The pager’s display shows the exact origin and the type of alarm call received. They are supplied with a belt clip holster and a bungee cord to reduce the chance of accidental damage.


Datastore software package RED234

The software package enables all events on the Red Alert system to be logged on a PC. The date, time, location and type of alarm call will be recorded along with reset and fault reports. A dedicated PC and printer is not required and the programme can be minimised and run in the background.
