• The maximum wire run distance between the first and last unit in an

interconnected system is 1000 feet.

• Figure 4 illustrates interconnection wiring.  Improper connection will

result in damage to the alarm, failure to operate, or a shock hazard.

• Make certain alarms are wired to a continuous (non-switched) power

line.  NOTE: Use standard UL listed household wire (as required by
local codes) available at all electrical supply stores and most hardware
stores.

• For alarms that are used as a single station, DO NOT CONNECT THE

RED WIRE TO ANYTHING. Leave the red wire insulating cap in place
to make certain that the red wire does not come into contact with
any metal parts or the electrical box.

CAUTION: This unit is sealed. The cover is not removable!

1. After selecting the proper smoke alarm location as described in sec-

tion 1 , install a compatible electrical box.

2. Connect the AC QUICK CONNECT harness as

described in the WIRING INSTRUCTIONS and,
attach the included mounting bracket to the
electrical box using the included hardware in
the appropriate mounting holes (see figure
5). Be sure the foam seal on the mounting
bracket completely covers the electrical box
cut out hole and makes complete contact
with the ceiling/wall surface.  The mounting bracket is keyed so that

the alarm fits in one orientation only.  Pull the AC QUICK CONNEC-
TOR through the center hole in the mounting bracket.

3. After you have finished wiring the Quick Connect harness and attach-

ing the mounting bracket, install the alarm on the bracket. Insure the
alarm is properly aligned to prevent breaking the keying feature off of
the mounting bracket.

5. Install the alarm on the mounting bracket by rotating the alarm in a

clock-wise direction until the alarm stops.

6. Turn on the AC power. The green AC Power On Indicator should 

be

lit within 30 seconds of when the alarm is operating from AC
power.

Mounting Holes for 3 1/2” 

spacing round ceiling boxes.

Mounting Holes for 

2-gang electrical boxes.

OPERATION: The smoke alarm is operating once AC power is applied
and testing is complete. When the smoke alarm ionization chamber
senses products of combustion, the horn will sound a loud (85dB) tem-
poral alarm until the sensing chamber is cleared of smoke particles.

The backup battery is activated as soon as AC power is supplied and will
remain active until the alarm reaches the end if its useful life or is manu-
ally deactivated.

To permanently deactivate the battery for return or disposal purposes
prior to it reaching end of life: turn off AC power, remove the alarm
from the mounting bracket, disconnect the AC wires, puncture the label
on the back of the unit, and press the small switch using a pen or other
thin tool. The alarm will rapidly beep 10 times indicating that it has been
deactivated.

CONTROL: The “HUSH” feature has the capability of

temporarily desensitizing the alarm circuit for up to 8 minutes. This fea-
ture is to be used only when a known alarm condition, such as smoke
