The Zeta Beam Xtra (ZT-BEAM/XTRA) is a motorised reflective optical beam smoke detector for protecting large open areas over distances of 7 to 70 metres. It is supplied with a low-level controller and one reflective cover. The motorised head aligns itself to the centre of the reflector during commissioning and automatically keeps alignment as the building moves, reducing false alarms and maintenance visits. It is compatible with most major fire panels and can be connected to an addressable loop via a zone monitor or Zeta SMM-B mini module.
