Infrared Staff Protection Systems

For security guards, prison officers and drug rehabilitation workers, the threat of personal attack is all too apparent. Unfortunately, in today’s increasingly violent society, doctors, nurses, teachers, civil servants, shopworkers, night porters and cashiers are just as vulnerable. The problem is, how do you safeguard against the risks? Enter Quantec Responder, the infrared staff protection system that highlights exactly where an attack is taking place within seconds.



Protecting staff

All at risk staff carry a special rechargeable transmitter which they attach to their clothing. Should an attack take place, they simply activate the transmitter to fill the area with infrared and radio signals.  These signals are picked up by a special receiver which instantly informs the system that an attack is taking place. An urgent, piercing alarm is then sounded throughout the building and the exact location of the incident is shown on all displays for the swift response of security staff. As part of C-TEC’s Quantec Addressable Call System, Responder includes a variety of lower priority call levels which can be used to call for assistance as a dangerous situation develops. Calls of this nature are reported directly to security staff and can often result in incidents being diffused before staff are verbally or physically abused.



Securing buildings

Before assailants strike, they must first gain access to the areas where their victims are located. Some professionals (doctors, nurses, teachers, etc.) must work in the firing line by default. Others, such as cashiers, civil servants and receptionists, are afforded some protection from the buildings and offices they work in. Responder can help reinforce this protection by monitoring areas to which access is restricted. In addition to protecting areas where staff are located, Responder’s monitoring points can also be used to secure drug cupboards, store rooms and fire exits. Supplied complete with an isolating keyswitch to reduce the risk of false alarms, they can also be connected to pressure mats, vibration sensors and passive infrared sensors for even more comprehensive protection.



Improving communication

Responder’s lowest priority ‘standard’ call level can be used for a whole host of applications, many unrelated to staff security. From disabled persons toilet alarms in public buildings to interview room call systems in housing offices, Responder’s vast array of call points, ceiling pulls, overdoor lights and reset points can achieve it – at a fraction of the cost of installing separate, dedicated systems.



Responder’s range of rechargeable dual-action infrared/radio transmitters have a typical infrared transmitting range of 10m (line of sight) and a typical radio transmitting range of around 60m.

Each transmitter has two infrared emitters (one on each side to maximise performance), two buttons (A & B) and a retained ‘pull clip’. Depending on its configuration, pressing a transmitter’s buttons or activating its ‘pull clip’ will generate a standard, help required, emergency or staff attack call on a compatible Quantec infrared and/or radio receiver.

Housed in a tough plastic enclosure, each transmitter provides battery low indication as standard and can be recharged fully in approximately 14 hours using the QT424/1 single way charging unit. A ten way charging unit, the QT424/10, is also available for sites with multiple transmitters.

Two pre-configured transmitters are available, the QT412RXA push for attack/pull for attack transmitter and the QT412RXCA push for call/pull for attack transmitter. If a different transmitter configuration is required, theQT423 configurator allows an engineer to reprogram any of the above transmitters to suit the operational requirements of an individual site.

Responder’s job is simple – to protect staff at all times. As such, we have ensured the integrity of the system is never compromised. In addition to the battery low indication feature on all QT412 range transmitters, Responder’s highly intelligent system controller constantly supervises all network devices to ensure they are working correctly. In the unlikely event that a device should fail, Responder instantly displays its unique ID number, helping to reduce system down-time, maintenance time and costs. A stand-by battery can also be added to the system to provide essential protection in the event of a power cut.
