What type of detectors can be used with Automist?

Detection components can be:

  • Wired, or
  • Wireless 

Important! The Automist controller monitors the status of any wired detectors for open circuit, short circuit, dirty sensor, and if the detector is removed from the base. Where wireless detectors are fitted, the system monitors for low battery, communication failure, dirty sensor, and if the detector is removed from the base. Once in fault mode, the unit will sound. The fault condition can be hushed for 12 hours by pressing the STOP button but only be permanently removed by addressing the fault. 

Wired detector

A 24-volt wired detector should be installed in a fire-protected cable where the cable is not protected by a fire-rated barrier between the detector and the spray head. The following wired detector is compatible with the Automist system:


Plumis' Custom Wireless detector

The Plumis Hydra Wireless Detector DT01 is a customised version of the Apollo multicriteria smoke + heat alarms 51000-150 / 51000-357 designed to EN 14604:2005 and UL217, respectively. The Plumis DT01 includes a proprietary 2.4GHz wireless communication to the sprayheads to indicate a potential fire. Combining a smoke alarm with a temperature sensor improves response times for both flaming and smouldering fires and reduces false alarms from certain nuisances such as cooking fumes. It is CE Marked to the harmonised European standards that apply to this alarm.
