MAINTENANCE
WARNING
To avoid
a
potential electrostatic discharge (ESD), do not wipe or rub the surface of
the EXP-SD-SFC-120V-V1
sensor
module.
NOTE :
The EXP-SD-SFC-120V-V1 Smoke Detector contains no user serviceable
components and should never be opened. The 3EXP-SD-SFC-120V-V1 wiring
compartment
is
the only part of the
smoke
detector that should be opened by the
user in the field.
ROUTINE INSPECTION
Regularly scheduled maintenance is not required, however the EXP-SD-SFC-120V-V1
cover and smoke chamber should be inspected periodically when detectors are located in
abnormally dirty or dusty environments, to ensure the smoke chamber is not blocked by dirt or
debris.
The smoke detector can be tested using the same methods employed for any photo-electric
detector. Det-Tronics recommends using a test aerosol smoke dispenser for periodic
maintenance of the detector.
