RHD212
RATE-OF-RISE TEMPERATURE
DETECTOR WITH RELAY BASE
Installation Manual No: 18020746
GENERAL DESCRIPTION:
The
RHD212
is a special kit for using in intruder alarm systems. The kit includes the
rate-of-rise temperature fire detector
RHD-2
and relay base
DB-12L/U
(12V)
.
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 to natural heat sources, e.g. above cookers,
ovens or fire places.
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 open it
for a service schedule
maintenance and cleaning you have to use the plastic key. Light press with the plastic
key
into the base opening and at the same time rotate the detector head counter-
clockwise.
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 as 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. Apply power to the detector.
2. Wait for 30 sec.
3. Apply the heat tester (
Cordless Heat Detector Tester or Heat Tester 110V>240V
) at
a distance 20cm to test the heat part of the detector. Within 8 sec the fire detector will
enter in fire condition. Both LEDs will light up.
4. Power off the detector for 2sec minimum. After resetting the detector will enter in
duty mode and the LEDs will light 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.
