    Zeta Reflective Beam Smoke Detector 7-70 Metres (Including Controller and 1 Reflector)

    Developed to overcome the problems of old outdated technology in beam detection, this motorised beam now means that beam detection can be used reliably to produce cost effective solutions for protecting large open areas.

    Building movement and accessibility have in the past, made beam detection unreliable, difficult, time consuming to commission and hard to maintain, but now by using the advanced motorised technology of the Zeta Beam Xtra unreliability is no longer a problem. The ZT-BEAM/ XTRA will self align itself to the centre of the reflector when commissioning and will automatically keep alignment with the reflector when building movement occurs. This intelligent motorisation will mean less false alarms therefore saving time, resources, reputations and ultimately money.

    USE SMM/B TO MAKE THIS ADDRESSABLE Zeta Special Mini Modules.
