EMA-VM-TR Remote alarm system

Monitors technical rooms and cable distribution cabinets:
reacts if someone opens the door, breaks in, climbs through or reaches inside.

For monitoring 2 to ≥ 12 signal lines over distances up to 80 km
based on DIN VDE 0833-1, -3, -4

For monitoring technical rooms and cable distribution cabinets

  • Sensors Art. Nos. 49.01 EMA-VM or 49.03 EMA-VM-TO
    (with TO dead-zone box) remain triggered as long as the door is still open
  • After the cover is closed, the sensor is deactivated and on alert. This happens fully automatically.
  • Temperature resistance – 40 °C to + 70 °C


Particular features:

  • Various states, e.g. opening, entry, water levels, can be monitored simultaneously, by setting up the appropriate EMA-VM and GMA-VM remote alarm systems in series. If a GMA-VM is activated, it can be re-set to alert within 3 min, after the cause of triggering has been removed and the signal generator has been replaced (replacement material is required).
  • When several remote alarms are in use, the precise location of the alarm for water, heat/fire or unauthorised entry is made possible if a dead-zone box (with dead-zone fibres) is utilised.
