Allows System Sensor reflected beam detectors to be installed at separations between 70-100m. Four 8"x8" reflectors must be used at these distances to provide enough reflected infrared light.

System Sensor beam detector mounting kit, allowing both the detector and reflector to be mounted on either a vertical wall or the ceiling.

Allows System Sensor reflected beam detectors to be mounted when surface wiring is used. Must be used with mounting the transmitter/receiver unit with the multi-mount kit (BEAMMMK).

Allows the transmitter/receiver of reflected beam smoke detectors to operate in environments prone to condensation, by maintaining the unit's temperature at a slightly higher temperature than the surrounding air.

Allows beam smoke detector reflectors to operate in environments prone to condensation formation by maintaining a reflector temperature at a slightly higher temperature than the surrounding air. Requires a 24V power supply.

This Open-Area Smoke Imaging Detection (OSID) uses dual wavelength projected beams and optical imaging technology, as a low-cost, reliable and easy-to-install means to help overcome false alarm incidents and alignment difficulties.

The detector transmits an infra-red light beam to a reflector up to 100m from the transmitter-receiver. If the reflected incoming beam is obscured by smoke, a fire alarm is initiated.

Analogue addressable reflected beam smoke detector, with a combined transmitter-receiver unit which can operate up to 100m. Compatible with Pertronic F220 and F100A fire panel AA circuits

A laser alignment tool which clips onto the eyeball of OSI/OSID beam smoke detectors. Used appropriately, the red laser shows the location, and alignment required, to align the transmitter/receiver with the reflector.
