INSTALLATION AND MAINTENANCE INSTRUCTIONS

Smoke Alarm Description

Smoke Alarm Power Requirements

Power input rating to the smoke

 

alarm is 12/[email protected] amp. Power 

supply and smoke-alarm installation must conform to the electrical codes 

in your area and CAN/ULC S553. It is recommended that wiring be

 performed

 

 by a licensed electrician.

Smoke

 

alarm Limitations

This smoke

 

alarm is designed for residential use only. This smoke

• 

alarm is self-restoring and does not lock into an alarm condition.

Smoke

 

alarms will not sense a fire if the smoke does not reach 

• 

the sensor. In order for a smoke

 

alarm to sense smoke, it must be 

installed in the immediate vicinity of the fire. In addition, smoke from 

fires in chimneys, in walls, on roofs, in remote parts of the building, 

or on another level from where the smoke

 

alarm is located, may 

not reach the smoke

 

alarm quickly enough for occupants to escape 

unharmed. For this reason, the installer shall install smoke

 

alarms 

on every level, in every sleeping area, and in every bedroom of the 

household.

Smoke

 

alarms may not be heard. The alarm horn in this smoke

 

• 

alarm meets or exceeds current Underwriter's Laboratories 

standards. However, if the smoke

 

alarm is not located in the 

same room as the occupant, or if it is blocked by a closed door 

or normal noise, the alarm horn may not be heard. In addition, 

sound sleepers, or persons who are under the influence of drugs or 

alcohol may not hear the alarm or be able to react to it. Therefore, 

locate this smoke

 

alarm, which has a sounder rated at 85dBA 

at 3 meters, on every level, in every sleeping area, and in every 

bedroom of the household.

In general, smoke

 

alarms may not always warn you about fires 

• 

caused by carelessness and safety hazards like smoking in bed, 

violent explosions, escaping gas, improper storage of flammable 

materials, overloaded electrical circuits, children playing with 

matches, or arson.

Smoke

 

alarms are not fool-proof. Like all electronic devices, 

• 

smoke-alarms have limitations. No type of smoke-alarm can 

sense every kind of fire every time. In addition, smoke from slow, 

smoldering fires rises slowly and may not reach the smoke

 

alarm 

until actual flame breaks out. This type of smoke may not reach the 

smoke

 

alarm in time for occupants to escape unharmed. Smoke

 

alarms are not a substitute for life or property insurance. Though 

smoke

 

alarms have been responsible for saving many lives, they 

are not warranted or implied to protect lives or property in the 

event 

of a fire.

To keep your equipment in excellent working order, ongoing 

• 

maintenance is required per the manufacturer’s recommendations 

and ULC, a preventative maintenance agreement should be 

arranged through the local manufacturer’s representative.Though 

smoke

 

alarms are designed for long life, they may fail at any time.

Therefore, smoke

 

alarms shall be replaced after being in service 

for 10 years. Any smoke

 

alarm, fire alarm equipment, or any 

component 

o

f that system which fails shall be repaired or replaced 

as soon as possible.

Where to Install Smoke Alarms

Warning: 

As a minimum requirement, smoke alarms must be installed in 

accordance with CAN/ULC-S553. In addition, observe all local and national 

building and electrical codes.

Connecting Auxiliary Devices with Relay

This smoke-alarm has a built-in relay which may be used to activate 

auxiliary devices such as bells, horns, and door closers. The relay contacts 

automatically close approximately eight (8)  seconds after the unit goes 

into alarm, and automatically resets approximately five (5) seconds after 

the alarm stops. For wiring refer to Figure 8. Auxiliary voltage and current 

requirements must be within relay contact ratings and appropriate wiring 

must be used.

How to Interconnect Smoke

 A

larms

NOTE:  Interconnect smoke

 

alarms within one household only. If smoke

 

alarms are interconnected between households, nuisance 

alarms  

 

will  occur when a smoke

 

alarm in another residence is 

tested.  

The model 2012JA has two interconnection modes shown 

in

table 1.

Up to twelve 2012JA smoke-alarms may be interconnected. The 

• 

2012JA smoke-alarms may also be interconnected with 2012H 

(A) when they all work at 12VDC supply voltage by using SIGRLY 

interconnecting terminal. If one smoke

 

alarm senses smoke, all of 

the interconnected units will sound in SIGSND mode, the relays 

of the interconnected units will be activated approximately eight 

seconds after horns sound in SIGRLY mode. After interconnecting 

the smoke

 

alarms, push and hold the test button for more than 3 

seconds on one unit. The alarm horns on all of the other smoke

 

alarms should sound if they are connected correctly.

If any interconnected smoke

 

alarm is activated by another unit, it 

• 

senses smoke, the unit will go into local alarm state with the LED 

flashing quickly.

Connect the smoke

 

alarms together by interconnecting all the 

• 

SIGSND terminals to each other and all GND terminals to each 

other in SIGSND mode, interconnecting all the SIGRLY and GND 

terminals to each other in SIGRLY mode. (See Figure 7.) Use 22 

guage (#22AWG) or larger two-conductor standard wire.

If smoke

 

alarms will not be connected, DO NOT use the 

SIGSND, 

 

• 

SIGRLY and GND terminals.

The LEDs on all smoke

 

alarms should flash once about 40 seconds 

• 

when power is turned on to the units.Test smoke

 

alarms after 

interconnection wiring are complete.

Cautionary Note:

  Test interconnection wiring after installation is 

completed. Test each unit in a system and make sure 

all other units alarm. FAILURE TO OBSERVE ANY 

OF THESE CONDITIONS CAN CAUSE SYSTEM 

MALFUNCTION AND/OR DAMAGE TO THE ALARMS.

Testing Information

You should test your smoke

 

alarm at least once a week to assure 

• 

yourself of its operation, as recommended by ULC. Test the smoke

 

alarm by firmly depressing the test switch located on the smoke

 

alarm cover (marked “Push and Hold to Test”) FOR MORE THAN 3 

SECONDS (See Figure 9). The alarm horn should sound, and the 

LED should flash rapidly. When the test switch is pushed and held 

for more than 8 seconds, the relay will be activated.

In an interconnected system, all of the smoke

 

alarms should sound 

• 

their alarm horns when any one of the test buttons is pushed and 

held for more than 3 seconds. The alarm horn sounds if the smoke

 

alarm is working properly. 

This is the only way to be sure the 

smoke

 

alarm

 

is working. Test the smoke

 

alarm weekly. If the 

smoke

 

alarm fails to test properly, have it repaired or replaced 

immediately.

DANGER: If the alarm horn sounds an alarm and you are 

not 

• 

testing the smoke

 

alarm, the unit has sensed smoke

 or 

 

combustion particles in the air. THE ALARM HORN IS A 

WARNING 

OF A POSSIBLY SERIOUS SITUATION. IT REQUIRES 

YOUR 

IMMEDIATE ATTENTION.

The alarm could be caused by a nuisance situation. Cooking 

smoke 

• 

or a dusty furnace can cause the smoke-alarm to sound. If 

this 

happens, open a window or fan the air to remove the smoke 

or 

dust. The smoke

 

alarm will turn itself off as soon as the air is 

completely clear. 

DO NOT TURN OFF POWER TO THE SMOKE

ALARM. THIS WILL REMOVE YOUR PROTECTION.

Monitoring Your Smoke

 A

larm

Once the smoke

 

alarm is powered, a green LED flashes once about 40 

seconds. This signals that the smoke

 

alarm is receiving power and is in 

the detection mode. If the smoke

 

alarm is not operating properly, the 

green 

LED will be OFF. (If  so, have the smoke

 

alarm repaired or replaced  

immediately.)  When  the smoke

 

alarm senses smoke, the green LED will 

flash rapidly. If the initiating smoke

 

alarm senses smoke and signals other 

interconnected smoke

 

alarms to sound their alarm horns, their LEDs will 

stop flashing. See TABLE 2 for specific LED functions.

The smoke

 

alarm will automatically return from Alarm to Normal state 

when the reason for alarm, as the presence of smoke, is completely 

removed.

As the fire is very dangerous for your family, usually you must draw a 

family escape plan including a map which shows all your home windows 

and doors, less than two escape routs, a safe meeting place and other 

required things in your

 area. 

Furthermore your family members should practice the escape plan 

at 

least twice a year.

Cleaning and Maintenance

DANGER: Electrical Shock Hazard. 

Turn off power to the smoke

 

alarm at 

the main service panel before cleaning the smoke

 

alarm.

This smoke

 

alarm has been designed to be as maintenance-free as 

possible. However, regular testing (see “Testing” above) and periodic 

maintenance are necessary.

To clean the smoke

 

alarm, turn off power and vacuum the outside of the 

smoke

 

alarm with the soft brush attachment of a vacuum cleaner. Do this 

at least once every year, preferably every six months. 

DO NOT ATTEMPT 

TO CLEAN THE SMOKE

 

ALARM IN ANY OTHER WAY.

If the smoke

 

alarm requires service, do not attempt to service it yourself

 

this will

 void your warranty. Return the smoke alarm to your local System

Sensor 

distributor or agent. Enclose a note describing what is wrong 

with the 

smoke alarm.

Special Note Regarding Smoke

Figure 9:

Smoke alarms are designed to provide early warning of developing fires at a 

reasonable cost. They monitor the air and can sense smoke, providing 

precious minutes for you and your family to escape before a fire spreads. 

Early warning fire detection is best achieved by the installation of fire 

detection equipment in all rooms and areas of the household. 

Model 2012JA is a photoelectric smoke alarm designed for open area 

protection in a residential building. It has a built-in relay which may be used to 

activate auxiliary devices such as bells, horns, and door closers. The relay 

contacts automatically close 8 seconds after the unit goes into alarm, and 

automatically resets approximately 5 seconds after the alarm stops. A 

piezoelectric horn in each smoke alarm produces an audible 85dBA temporal 

tone evacuation signal when the unit alarms or an interconnected one alarms. 

This temporal tone evacuation signal complies with CAN/ULC-S531-02.   

The signal consists of 3 beeps each 0.5 seconds long. spaced 0.5 seconds 

apart, followed by 1.5 seconds of silence. These smoke alarms can be 

interconnected with the SIGSND and GND terminals for a system of up to 12 

units per premises so when one smoke alarm sounds its evacuation signal it 

causes the other connected smoke alarms to sound as well. They also can be 

interconnected with the SIGRLY and GND terminals, when any one alarms, 

all the interconnected units’ relays will be activated approximately 8 seconds 

after their horns sound. The smoke alarm has a built-in silence/test push 

button to silence or test. If the silence/test button is pushed for less than 3 

seconds, this is a silence instruction, the smoke alarm will reduce its 

sensitivity and give an audible trouble signal for about 8 minutes. If the 

silence/test button is pushed and held for more than 3 seconds, this is a test 

instruction (See “Testing” below for more detailed instructions.). 

NOTE: If the smoke alarm is not in alarm but beeps and flashes every 40 

seconds, it is in the silence state. To exit this silence state when the unit 

is not in alarm, press and hold the silence/test button for more than 3 

seconds to do a test.
