ZETA UK Fyreye Addressable Optical Smoke Detector

The FEAO2000 is an analogue addressable Optical smoke detector that works to the Zeta Addressable protocol, compatible with Zeta alarm system control panels only.

The optical chamber consists of a removable plastic mesh, an IR LED and an IR receiver. These are arranged such that in normal conditions (clean air), no IR from the LED will reach the IR receiver.

Every second, the IR LED emits a burst of collimated infra red light. If there is any smoke in the chamber, it will scatter the IR, allowing it to reach the receiver. The amount of IR reaching the receiver is converted to an analogue smoke value, and sent digitally back to the fire alarm control panel as part of the detectors communication protocol.

The detector is supplied with a locking screw to prevent removal of the head by unauthorised personnel. The detector will return an analogue value of 55 counts with a smoke obscuration level of 2.4% obscuration per metre.

The Fyreye optical smoke detector is particularly suitable for detecting optically dense smoke, involving materials such as soft furnishings, PVC, plastic, foam, and similar materials which produce large visible small particles (0.5mm to 10 mm).
