System Sensor Smoke Sensor

Figure 4. Sloped, peaked, or gabled ceilings.
Do not install smoke alarms in the following loca-
tions:
ν
In or near areas where combustion particles are
normally present such as kitchens; in garages
where there are particles of combustion in vehicle
exhausts; near furnaces, hot water heaters, or gas
space heaters.
ν
On the ceiling in rooms next to kitchens where
there is no transom between the kitchen and these
rooms.
ν
In damp or very humid areas, or next to bath-
rooms with showers. Install sensors at least 5 feet
(1.5 meters) away from bathrooms.
ν
In very cold or very hot areas.
ν
In dusty, dirty, or insect-infested areas.
ν
Near fresh air inlets or returns or excessively
drafty areas. Air conditioners, heaters, fans, and
fresh air intakes and returns can drive smoke
away from smoke alarms.
ν
In dead air spaces at the top of a peaked ceiling or
wall/ceiling intersect. Dead air may prevent
smoke from reaching a smoke alarm.
ν
Near fluorescent light fixtures. Install smoke
alarms at least 10 feet (3 meters) away from fluo-
rescent light fixtures.
Mounting
The mounting bracket must be separated from the unit
before you begin.
To mount the smoke alarm:
1.
Secure the mounting bracket directly onto wood
surfaces using No. 8, 1½ inch wood screws. If
mounting onto plaster or dry wall, use appropri-
ate anchors.
2.
Align the arrows on the mounting bracket with
the raised marks on the smoke alarm. Turn the
smoke alarm clockwise until it locks in place.
Testing
Test each smoke alarm every week to verify that its
siren and signal integrity are adequate.
To test the smoke alarm:
1.
Put the panel in sensor test mode. Refer to the
panel’s installation manual for details.
Note:
To avoid a fire department dispatch from the
central station, make sure the panel is in sen-
sor test mode before testing.
2.
Use a pencil or small screwdriver to press and
hold the test button on the smoke alarm for 5 sec-
onds (Figure 1).
The sensor should immediately send an alarm signal
to the panel, causing it to beep up to 16 times, or by
sounding one high-pitch beep from system sirens
(refer to the panel’s installation manual for response
details).
After 2.5 seconds, the siren inside the smoke alarm
sounds and the status light flashes rapidly.
Maintaining the Smoke Alarm
Batteries
The 3-volt lithium batteries may last as much as 5
years before they need to be replaced.
Replace both batteries when the smoke alarm or panel
notifies you that the batteries are low.
Cleaning the Smoke Alarm Chamber
Clean the smoke alarm chamber at least once each
year.
To clean the smoke alarm chamber:
1.
Place the panel in sensor test mode.
2.
Remove the batteries. Do not remove the skirt.
3.
Follow the instructions in the section “Removing
the Shorting Blocks” to remove the cover and the
screen.
4.
Vacuum both the screen and the smoke chamber.
