Inspection and Maintenance
7
Function Test
Smoke detectors must be inspected every 3 months after
commissioning of the air conditioning system and
maintenance carried out at yearly intervals. Inspection
and maintenance can be carried out at the same time.
Inspection
Pressing the “Test/Reset” button on the smoke detector
or on the remote control terminal interrupts the circuit to
the control device on the fire damper which then closes.
On releasing the button, fire dampers with actuators
automatically return to the open position. Fire dampers
with solenoid or magnet release must be opened locally
by hand.
The fouling of the smoke alarm can be scanned directly on
the smoke detector using the diagnostic instrument and/or
via the remote control terminal.
For signal indication, see overview of functions, page 6.
Maintenance
Check the following:
– Application and installation position
(during commissioning and after system changes)
– Correct electrical connections and no loose wires in
terminals
– Electrical interaction of signal emitter, display and control
devices on fire damper
– Response of smoke alarm to smoke aerosol, e.g. cigarette
smoke or smoke from smoke cartridge. When the
permitted concentration limit is exceeded, the smoke
alarm interrupts the circuit to the control device on the
fire damper to be controlled and the damper closes
– Check response of air velocity monitor, e.g. switch off fan
For signal indication see overview of function, page 6.
Eliminating Faults
If inspection or maintenance has revealed any faults, these
must be repaired immediately. Faulty components must be
replaced only by original Trox spare parts.
Only the manufacturer may make repairs to the smoke
detector.
If a function test reveals that the smoke detector is working
correctly but the fire damper to be controlled is not closing,
the control device on the damper and the damper itself
must be checked for operation.
