WARNING
TO PREVENT DETECTOR CONTAMINATION AND
SUBSEQUENT WARRANTY CANCELLATION, THE
SMOKE DETECTOR MUST REMAIN COVERED UNTIL
THE AREA IS CLEAN AND DUST FREE.
INSTALLING THE BASE
1. To insure proper installation of the detector head to the
base, all the wires should be properly addressed at
installation:
(A) Position all the wires flat against terminals.
(B) Fasten the wires away from connector terminals.
2. If you use a jumper wire to connect the poles of
terminal 2 and 5 when testing the detector loop
continuity, be sure to remove the jumper wire prior to
the installation of the detector head.
3. The end-of-line device shown in fig. 1(a) and 1(b)
should be compatible with the control unit. The
end-of-line supervisory relay used should be rated for
the DC power voltage used.
4. Open area smoke detectors are intended for mounting
on a ceiling or a wall in accordance with the fire
standard in your country.
5. The base of the smoke detector can be mounted
directly onto an electrical junction box such as an
octagonal (75mm, 90mm or 100mm), a round (75mm),
or a square (100mm) box without using any type of
mechanical adapter.
INSTALLING THE HEAD
1. Align the components as shown in Figure 2.
2. Mate the detector head onto the base and twist
clockwise to secure it.
3.Do not install the detector head until the area is
thoroughly cleaned of construction debris, dusts, etc.
The maximum number of smoke detector installed in
the same detection zone is typically 30 units. Refer to
control panel manual.

ADJUSTING THE RELAY FOR NO/NC
The normal condition for the relay is “normally open”
(NO).
1. To adjust the normal condition of the relay to
“normally closed”(NC), insert a screwdriver into the
rectangular hole located on the side between the front
cover and base and rotate to remove the front cover.
2. Refer to figure 3. There is a jumper head next to the
relay on the PCB. Remove the jumper head and reinsert
it in the NC position.
3. Carefully replace the front cover.
Relay contact rating:
1A@30VDC,
0.5A@125VAC.
TESTING
1. All remote signaling systems, releasing devices and
extinguishing systems should be disconnected
during the test period and reconnected at the
conclusion of testing.
2. After energizing the detector head for approximately
one minute, check to see the indicator green LED
flashing once every 3~5 seconds. If green LED fails to
flash, it indicates the non-functioning of the detector or
faulty wiring. Re-check the wiring or replace the
detector if necessary.
3. Allow smoke from a cotton wick or a test smoke
aerosol to enter the detector-sensing chamber for at
least 10 seconds. When sufficient smoke has entered
the chamber, the detector will signal an alarm, this
being visible by a continuous illumination of the LED.
Reset each detector and/or control unit before
attempting to test any additional detectors in the same
zone. If the alarm fails in this step, it indicates a
defective unit, which requires service.

HEAT SENSOR TESTING
The detector to be tested should be subject to a flow of
warm air at a temperature of between 65°C and 80°C.
(This requirement can be met by some domestic hair
dryers).
Proceed as follows:
1. Switch on the warm airflow and check that temperature
is correct and stable.
2. From a distance of several inches, direct the airflow at
the guard protecting the thermistor. The detector
should alarm within 30 seconds.
3. Upon alarm immediately remove the heat source and
check that the red LED of the detector is illuminated.
Reset the detector from the control panel.
4. If a detector fails to activate within 60 seconds, confirm
connections and programming. If necessary replace
and return to distributor for recalibration.
5. After testing, check that the system is set for normal
operation and notify the appropriate authorities that the
testing operation is complete and the system is active
again.
NOT SUITABLE FOR INSTALLATION IN AREAS
WHERE AIR VELOCITIES EXCEED 300 ft/min
MAINTENANCE
The recommended minimum requirement for detector
maintenance consists of an annual cleaning of dust from
the detector head by using a vacuum cleaner cleaning
program should be agreed to the individual environment
in conformance with NFPA-72A standard.
Note: This product is factory sealed and does not
contain user serviceable parts. Opening THE
DETECTOR HEAD WILL VOID THE WARRANTY.
