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 local
requirements.
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

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 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 red LED
flashing once every 4-6 seconds. If red 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. 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
