UNTIL 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 the jumper wire to connect the poles of
terminal 2 and 5 when testing the detector
loop's continuity, be sure to remove the jumper wire
prior to the installation of the detector head.
3. The end-of-line device shown in Figure 1.a & 1.b
should be compatible with the control unit. The
end-of-line supervisory relay used should list the rated
DC power voltage used.
4. Per UL listing, open area smoke detectors are
Photoelectric

Installation Wiring Diagram
intended for mounting on a ceiling at least 6 inches
away from a wall or mounting on a wall between 4 and
12 inches away from a ceiling.
5. The base of smoke detector can be mounted directly
onto an electrical junction box: octagonal (3", 3.5" or
4"), round (3"), and square (4" length) boxes without
using any type of mechanical adapters.
INSTALLING THE HEAD
1. Align the components as shown in Figure 2.
2. Mate the detector head onto the base and twist it
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 OF THE RELAY POSITION
4-wire type: Adjust the relay set-position for wiring unit to the
security monitoring system through the following steps:
1. The reset position for the relays is "normally open"
(NO), when powering all the relays.
2. To adjust the relay set point, use a screwdriver to
loosen the two screws on the back of the base.
Figure 3 shows a jump head next to the relay on the
PCB, adjust it to select either the "normally
closed" (NC) or the "normally open" (NO) positions.
3. Relay contact rating:
1A @30VDC,
0.5A @125VAC.

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 powering the detector head for approximately
one minute, check if the red LED light is flashing
once every 1~3 seconds. If the red LED fails to
flash, it indicates that the detector is not functioning
properly or the possibility of having incorrect wiring.
Re-check the wiring or replace the detector if
necessary.
