Flashing LED’s – cover not removed?

A PROTECT Fog Cannon® provides audible (short beeps) and visual signals (flashing LEDs on the front).

Overview of LEDs *:

  • A Green LED flashes, when power is applied to the Fog Cannon™. The green LED lights up constantly, when the Fog Cannon™ has reached its working temperature and is ready for firing
  • A Yellow LED lights up when the fluid level is low
  • All LEDs turn off when the alarm is connected
  • Red LED:
    o One flash per 10 sec. means failure of mains power **
    o Three blinks per 10 sec. means signal from any fire alarm system for Fog Cannon™ *Δ
    o Four flashes per 10 sec. means low battery voltage **
    o Constant flashing: Serious error requiring intervention from an alarm installer *

* Diodes on Xtratus™: See manual page
** Requires service visits
Δ Could indicate key switch/other isolation
