Zeta Reflective Beam Smoke Detector 5-40 Metres (Including Controller and 1 Reflector) (ZT-BEAM)

Beam smoke detection was previously unreliable at protecting large areas as building movement and accessibility made these devices both inaccurate and and time-consuming to install and maintain. The Zeta Beam Reflective Beam Smoke Detector has been designed to intelligently overcome these issues to provide a cost-effective solution for optically detecting smoke over large areas.

The main reason that this device is so much more reliable is that it uses a motorised head unit to allow for accurate beam alignment with the reflector instead of a stationary head. On commision, the head unit will self-align with the centre of the reflector unit and automatically ensure it stays aligned with the reflector even if building movement occurs.

The ZT-BEAM is compatible with many major fire alarm system control panels and has a very low level of power consumption; it only uses 3mA at all times.

Designed to comply with EN54 Part 2, this beam smoke detector has a range of 5 to 40 metres. Range extension kits are also available to increase the range of the beam up to a massive 100 metres.

The clever design of this device ensures that false alarms are kept to a minimum, saving you time, resources and money and protecting your reputation.
