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. As per EN 54 standard, open area smoke detectors
are intended for mounting on a ceiling no less than
100mm from a wall or mounting on a wall than no less
than 100mm and no more than 300mm from a ceiling.
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 loop is 30 units.

ADJUSTMENT THE RELAY POSITION
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.

TESTING
1.
All the alarm signal services, releasing device and
extinguisher system should be disengaged during the
test period and must be re-engaged immediately 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 4~6 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.
