Notifier, a leading US-based manufacturer of commercial fire alarm systems, has introduced a new, advanced wireless interface system that is said to be ideal for historical and commercial properties.

The company, which is part of Honeywell's Home and Building Control business, said its advanced RFX Radio Frequency Wireless Interface System facilitates fire detection in situations where wiring is impractical.

"Because the RFX system is wireless, drilling for wire running is not required. This is ideal for facilities with materials such as marble or rock, museums, historical sites and commercial buildings aiming to preserve their ceilings or wall designs," said a company spokesman.

"The RFX wireless system uses a translation device (RFX) to allow communication between a Notifier intelligent fire alarm control panel and up to 80 wireless detectors, and operates within a 60-ft radius in any direction from receiver.

"The system monitors the status of each wireless detector and connects to the control panel's Signalling Line Circuit (SLC), which allows each and every device to have its own unique address and custom status indication.

"It increases flexibility of existing installations and features 100 per cent field-programmability with a built-in menu system."

The RFX wireless interface assembly consists of an RFX board, a mounting enclosure and an RFX-R receiver.

The RFX board contains all the connections necessary for the RFX wireless interface system to operate.

In addition, it contains a liquid crystal display that provides diagnostic information, and a CPU failure indicator.
