FUNCTIONING
IN

EVENT
OF
AN
ALARM
MESSAGE
WITH
THE
CONTROL
PANEL
IN
DELAYED
MODE
OF
OPERATION
THE YELLOW LED “EVACUATION DELAYED” IS ILLUMINATED !
A fire alarm message is triggered in the following cases:
-
An optical, a multi sensor or a linear detector detects smoke
-
A rate of rise detector detectors an abnormal temperature rise
-
A heat detector detects an excess of the maximum temperature
-
The flexi element of a manual call point is activated
-
The alarm contact of a technical supervision unit is switched
A fire alarm message is indicated by the following visual and acoustical signals:
-
The red LED “FIRE ALARM” lights up
-
The name of the detector loop appears on the LCD Touch screen
-
The built-in buzzer (continuous tone) is activated
-
The optional warning sounders are activated
-
The set evacuation-reaction time starts (default delay: 2 minutes – delay to be set via the PC
configuration software)
-
The alarm-direct controls are carried out
-
The alarm-delayed controls are only carried out after the time delay has elapsed.
If, after verification, no fire can be detected, the alarm message may have 2 possible causes:
-
The fire detector reacts to a temporary cause (a few examples):
There is an abnormal amount of dust present
There is a high concentration of volatile products (e.g. paint)
There is an abnormally high humidity (> 90%)
Smoke is caused by work (e.g. welding)
The ambient temperature is higher than 50°C
Influence of sunlight
The detector is located near a heat source (e.g. stove or oven)
The detector is surrounded by water vapor
-
The fire detector is faulty (internal technical fault or due to water damage)
