Mounting

❑

Alarms may not warn in time when fires are caused by 
smoking in bed, explosions, improper storage of flam-
mables, overloaded electrical circuits, or other hazard-
ous conditions.

❑

In or near areas where combustion particles are nor-
mally present such as kitchens; in garages where there 
are particles of combustion in vehicle exhausts; near 
furnaces, hot water heaters, or gas space heaters. 

❑

On the ceiling in rooms next to kitchens where there is 
no transom between the kitchen and these rooms.

❑

In damp or very humid areas, or next to bathrooms with 
showers. Install sensors at least 5 feet (1.5 meters) 
away from bathrooms.

❑

In very cold or very hot areas.

❑

In dusty, dirty, or insect-infested areas. 

❑

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.

❑

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. 

❑

Near fluorescent light fixtures. Install smoke alarms at 
least 10 feet (3 meters) away from fluorescent light 
fixtures.

The mounting bracket must be separated from the unit 
before you begin.

1.

Secure the mounting bracket directly onto wood sur-
faces using No. 8, 1½ inch wood screws. If mounting 
onto plaster or dry wall, use appropriate 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.

Test each smoke alarm every week to verify that its siren 
and signal integrity are adequate. Refer to the specific panel 
installation instructions for system response.

1.

Put the panel in sensor test mode. Although not neces-
sary for this model, it is a good practice to maintain. 
Refer to the specific panel installation instructions for 
details.
❑

Simon and Advent panels must be in sensor test. If 
not, you will not see anything at the panel.

!

2.

Press and hold the test button on the smoke alarm for 3 
to 4 seconds. 

The sensor should immediately transmit an alarm signal, 
causing the siren inside the smoke alarm to sound and the 
status light to flash rapidly. Refer to the panel’s installation 
instructions for response details.

After verifying that the siren and signal integrity are 
adequate, you may want to cover the center opening 
with your thumb. This will help reduce the siren noise 
until the test is completed.

Replacing Batteries

When the batteries need to be replaced, the unit transmits a 
signal to the panel. If the batteries are not replaced within 7 
days, the unit will chirp every 40 seconds until the batteries 
are exhausted.

If you test the smoke alarm or it goes into alarm during 
this 7-day period, chirp delay is canceled and the unit 
begins chirping immediately.

Constant exposure to high or low temperatures or high 
humidity may reduce battery life. Replace both batteries 
when the smoke alarm or panel notifies you that the 
batteries are low.

For UL installations, use the following battery brands: 
Sanyo CR123A, Panasonic CR123A, or Duracell 
DL123A. These can be obtained through Interactive 
Technologies, Inc. Do not mix brands.

Cleaning

Clean the smoke alarm chamber at least once each year.

1.

Place the panel in sensor test mode.

2.

Remove smoke alarm from mounting ring.

3.

Remove the batteries. 

4.

Separate housing from base.

5.

Remove screen and chamber housing.

6.

Vacuum screen, chamber housing, and chamber.
