It is to be used with UL Listed compatible control panels only. An advantage of this single-ended reflective design is that it is much easier to install than the dual-ended projected beam detectors. Alignment is quickly accomplished via an optical sight and a two-digit signal strength meter incorporated into the product. This means it can be used in open areas to provide early warning in environments where temperature extremes may exceed the capability of other types of smoke detectors. When smoke enters the area between the unit and the reflector, the smoke causes a reduction in the signal. When the smoke level reaches the predetermined threshold, an alarm is activated.

Fire Projects does SITC - supply, install, test and commission the Fireray , which is motorised reflective type optical beam smoke detector with auto aligning infrared optical beam smoke detector can be installed with up to two detector heads per system, thus saving on installation time and costs.
In addition, each system controller houses two pairs of fire and fault relays, one per detector. This innovative system has been designed from the ground up to include pioneering technology that fully addresses the needs of the installer and user, both now and in the future. The Fireray supplied by Fire Projects, combines an infrared transmitter and receiver in the same discrete unit and operates by projecting a well-defined beam to a reflective prism, which returns the beam to the receiver for analysis.
Smoke in the beam path causes a drop in power, which, if below a pre-determined level, results in an alarm signal. Fireray is quickest and easiest detector, which is getting system operation simplified by number of ground breaking features. A full range of installation acessories are available including the new Adjustment Bracket, which allows a greater degree of flexibility during installation.
Once detector head are connected, using esifit First fix system, and integral laser can be activated. This allows the reflective prism to be positioned quickly and with confidence. Once the laser has been used to coarsely align the beam, Auto-align take over and automatically steers the beam into the optimum position. During alignment the system automatically switches to high current mode and drops back to low current mode when in normal operation, however alignment is still possible to in low current mode.
