Fire Safety
In the event of fire, an extinguishing process normally occurs automatically and
triggers the two alarm stages "Fire alarm" and "Activated" before extinguishing is
activated. As explained in the following, there are different operating options to
affect the extinguishing process.
Fire alarm
A fire detector in the extinguishing area has detected a fire.
- The buzzer in the control unit is activated and the alarm horn signal "Fire alarm"
as a rule with a slow pulsating tone
- The red Leds "Detector Zone 1" or "Detector Zone 2" light up
- The red Led "Fire alarm" light up
- The red Led "Activated" flashes, indicating the pre-activated condition
In the case of a fire that justifies extinguishing, the second fire detector triggers
within a few seconds. If the second fire detector does not trigger for a longer period
of time, you can inspect the fire location, silence the alarm horn and the buzzer and
block automatic activation of extinguishing.
Here's how to proceed, in order to block the automatic activation of extinguishing:
1. Press the "Silence Buzzer" (6) key
2. Enable operating access level 2 (access code or key)
3. Press the "Silence Re-sound Horn" (5) key
4. Press the "Mode Select" (8) key
yellow LED « Automatic blocked » (16) and « Disabled » (6) light up (fixed)
If you find the alarming fire detector and the cause, you can reset the system and
cancel the blocking of the automatic activation of extinguishing.
