Because wireless detection systems do not require cable to connect between sensing devices and control equipment, the system designer can eliminate the costs associated with cable, conduit, fasteners, back boxes, and power supplies.


Wireless transmitters are fully supervised for the device input, and include indications for low battery and device enclosure anti-tamper triggers. Because wireless device transmitters regularly send check-in messages to the system control equipment throughout the day, the system is continually aware of the status of each and every transmitter. Transmitters immediately communicate status changes to the control equipment.


Frequency Hopping Spread Spectrum Technology (FHSS), coupled with Bi-directional RF Communication, Repeater Network Architecture and 200 Second Supervisory Polling, provides for the industry’s most secure and reliable wireless fire alarm network.


Traditionally, fire detection systems in industrial and commercial applications have used hard wired installations. These systems are generally installed at the time of construction or refurbishment, making the laying of cables not a great issue. However, certain applications do not lend themselves to this approach, such as occupied buildings, heritage sites, architecturally sensitive buildings and annexes. This is where wireless systems provide the ideal solution.

Xpander is a system in which individual detectors, call points and alarm devices communicate with the XP95 loop by radio signals. An interface is connected to the loop in the same way as any other interface, such as an input/output unit. The Xpander range benefits from the patented XPERT technology that is used in Discovery and XP95.

  • Easy to install.
  • XPERT card addressing.
  • Self-monitoring.
  • Proven technology.
  • No special control panel needed.
  • 868MHz radio channels.
  • Up to 15 devices per interface.
  • Up to 5 interfaces per loop.

All detectors within the Xpander range are supplied complete with mounting bases.
