6.4.8.1 Fire alarms
Internal fi re alarm
The air handling unit's internal temperature sensors serve as
fi re protection thermostats. An alarm is initiated if the supply
air temperature sensor registers more than 70 °C or when the
extract air temperature sensor registers more than 50 °C.
If an external Extract air/Room temperature sensor is connected
and activated, this works parallel with the extract air temperature
sensor of the AHU.
External fi ree alarm 1 and 2
External fi re alarm 1 (Terminals 6-7) and external fi re alarm 2
(Terminals 8-9) are used for external fi re-control equipment.
Alarm reset
The resetting of internal fi re alarms as well as the external fi re
alarms 1 and 2 can be individually selected to manual or auto-
matic.
After cool
The After cool function for electric air heaters can be individually
activated, for internal fi re alarms as well as external fi re alarms 1
and 2.
Fan operation at fi re alarm
The fans of the air handling unit can be used for evacuating
smoke, etc. It is possible to individually select the type of fan
operation for each separate fi re alarm.
If the AHU is idle, the fans selected start up (10-100%), irrespec-
tive of whether stop (all types) is activated.
The AHU's damper relay is energized and the AHU's operation
relay is de-energized. The damper that should be open in event
of fi re, shall be connected to the damper relay (control unit ter-
minals 28-30). The damper that should be closed in event of fi re,
shall be connected to the operation relay (terminals 26-27 of the
control unit, potential-free contact).
Priority
The mutual priority of the internal and the external fi re alarms
can be set. If automatic is selected, this means that the fi rst input
to be activated is given priority.
