The monitoring loss pneumatic activation device may only be used in accordance with system approval in stationary C02-, argon-and nitrogen fire extinguishing systems. It facilitates monitoring of the permissible loss (5% - 10% supply per control cylinder). If the permissible margin of loss is exceeded the beam weight falls and actuates a reed contact limit switch.
The limit switch sends a fault message to the monitoring control panel and the fault is indicated locally via LED.
