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 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
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 instructions
Fig. 2 Fitting detector head onto base
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.
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 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

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.
zCAUTIONS
This heat detector is particularly designed to initiate and
activate emergency action, but will do so only when it is
used in conjunction with an authorized fire alarm system.
This detector must be installed in accordance with NFPA
Standard 72.
The purpose of design of heat detectors is meant to
protect property, not life. The heat detectors do not provide
early warning of fire and cannot detect smoke, gas,
combustion particles, or flame. They will alarm when
temperature at the heat detector reach 57oC (135oF) or
above. Given the rapid growth of certain types of fires, heat
detectors cannot be expected to provide adequate warning
of fires resulting from smoking in bed, inadequate fire
protection practices, violent explosions, escaping gas, and
improper storage of flammable liquids like cleaning solvents,
other safety hazards, or arson.
Heat detectors do not always detect fires because the
fire may be a slow-smoldering, low-heat type (producing
smoke), or because they may not be mean where the fire
occurs, or because the heat of the fire may bypass them.
Heat detectors will not detect smoke, gas, flames, or
combustion particles.
Heat detectors are components in professionally installed fire
alarm systems. They will not function if they have been
improperly wired into the fire alarm system or if power to
them is disconnected for any reason.
Heat detectors should be tested and maintained following
the instructions in this manual. To be safe, they should be
replaced after they have been installed for ten years.
Refer to NFPA 72 for application.
CAUTION: DO NOT ATTEMPT TO DISASSEMBLY OF THE
FACTORY SEALED HEAT DETECTOR. THIS ASSEMBLY
IS SEALED FOR YOUR PROTECTION AND IS NOT
INTENDED TO BE OPENED FOR SERVICING BY USERS.
TO OPEN THE DETECTOR HEAD WILL VOID THE
WARRANTY.
