System Sensor Smoke Sen-

CAUTION:

If the smoke sensor is attached to 
the mounting bracket, the panel 
cannot learn the ID.

To add the smoke alarm to panel memory:

1.

Put the panel in Program Mode/Learn Sensors.

2.

Select a group and sensor number. 

3.

Use a pencil or small screwdriver to press the 
smoke alarm test button for at least one second.
The panel will indicate that the sensor has been
learned. If you release the test button in less than
2.5 seconds, the smoke alarm siren will not sound.

Mounting Guidelines

Determine the best mounting location for the smoke 
alarm using the following guidelines:

UL Note:

DO NOT mount a smoke alarm to a drop 
ceiling tile; mount it to a metal runner.

ν

Mount all smoke alarms within 100 feet of the 
panel.

ν

Install a minimum of two smoke alarms in any 
household, no matter how small it is.

ν

Put a smoke alarm in the hallway outside of every 
bedroom area. A minimum of two smoke alarms 
are required in homes with two bedroom areas 
(see Figure 4).

A78-1171-02

Figure 1. Residence with multiple sleeping areas.

ν

Put a smoke alarm on every level of a multi-level 
residence (Figure 5).

ν

Install basement alarms on the ceiling at the bot-

tom of the basement stairwell.

Figure 2. Multi-level residence.

ν

Install smoke alarms on the ceiling as close to the 
center of the room as possible. If this is not practi-
cal, install it on the ceiling no closer than 4 inches 
(10 cm) from any wall or corner (Figure 6).

ν

If ceiling mounting is not practical, install on an 
inside wall between 4 and 6 inches (10 and 15 cm) 
from the ceiling (Figure 6).

ν

Put smoke alarms at both ends of a bedroom hall-
way if the hallway is more than 30 feet (9 meters) 
long. Large rooms over 900 square feet require 
more than a single sensor.

Figure 3. Smoke alarm mounting locations.

ν

Areas with rough ceilings or short, transom-type 
walls coming down from the ceiling require addi-
tional smoke alarms.

ν

Install second-floor smoke alarms on the ceiling at 
the top of the first-to-second floor stairwell. Be 
sure no door or other obstruction blocks the path 
of smoke to the unit.

ν

In rooms with sloped, peaked, or gabled ceilings, 
install smoke alarms 3 feet (0.9 meter) measured 
down on the slant from the highest point of the 
ceiling (Figure 7).
