OPTICAL SMOKE/HEAT
DETECTOR & BASE
Technical Sheet
ref C1694A
CSD-2 Sensor
INSTALLATION
1. Choose the proper place for installation of the fire detector.
Refer to the given installation instructions.
Note: Do not install the detector near sources of steam,
condensation or smoke and close to natural heat sources.
2. If you want to “lock” the detector to the base remove the little
“tooth” (with the triangle shape) and break the plastic key
off the base. Keep the plastic key in safe place to be able to
open the detector later.
3. Mount the relay base on the ceiling of the protected premises
using fixings according the mounting surface.
4. Connect the detector base to the intruder alarm panel using
the wiring diagram.
ATTENTION: Disconnect the main power supply before
installing the detector!
5. Insert the detector into the base and rotate clockwise until it
drops into place. Continue to rotate the detector until it locks
to the base - a click is heard.
6. If the detector has been locked to the base, when opening it
for a service schedule maintenance and cleaning you have
to use the plastic key. Lightly press the plastic key into the
base opening and at the same time rotate the detector head
counterclockwise.
ATTENTION: To clean the wire mesh you have to remove the
detector’s PCB and then carefully to disassemble the smoke
chamber from it. Clean the wire mesh and mount the chamber
back on the PCB and observe the arrows - they have to
coincide, then slightly press the chamber to the detector’s PCB.
Next you have to mount the PCB back to detector’s plastic body.
Find the color dot sticker on the PCB and orientate it to the mark
on the plastic body (visible from the outside). The hole next to
the color dot have to coincide with the pin on the plastic body.
Gently press downwards to fix the PCB in place.
TESTING THE DETECTOR
To test the detector use a smoke probe:
1. Exert influence on the fire detector by smoke generator
(Dispenser) or by aerosol simulator of smoke to test the
optical part; or use heat tester (Cordless Heat Detector Tester
or Heat Tester 110V>240V) at distance of 20 cm to test the
heat part. Within 8 sec the fire detector will enter into fire
condition.
Both LEDs will light up.
2. Power off the detector for 2 sec. minimum. After resetting the
detector will enter in duty mode and the LEDs will turn off.
SERVICE MAINTENANCE
1. Inspection for visible physical damage - weekly.
2. Operational test in real conditions - monthly.
3. Check and clean dust contamination - six months.
4. Check and clean base and head contacts and connections -
annually.
