Important! Read Before You Install This Smoke Alarm
Read “Where To Install Smoke Alarms” and “Where Not
To Install Smoke Alarms” before beginning. This unit
monitors the air, and when smoke reaches its sensing
chamber, it alarms. It can give you more time to escape
before fire spreads. This unit can ONLY give an early
warning of developing fires if it is installed, maintained
and located where smoke can reach it, and where all
residents can hear it, as described in this manual. This
unit will not sense gas, heat, or flame. It cannot prevent
or extinguish fires.
DANGER!
ELECTRICAL SHOCK HAZARD. Turn off power to the
area where you will install this unit at the circuit
breaker or fuse box before beginning installation.
Failure to turn off the power before installation may
result in serious electrical shock, injury or death.
WARNING!
This unit will not alert hearing impaired residents. It
is recommended that you install special units which
use devices like flashing strobe lights to alert hearing
impaired residents.
WARNING!
Installation of this unit must conform to the electrical
codes in your area; Article 760 of the National
Electrical Code (NFPA 70), NFPA 72, 101; SBC (SBCCI);
UBC (ICBO); NBC (BOCA); OTFDC (CABO), and any
other local or building codes that may apply. Wiring
and installation must be performed by a licensed
electrician. Failure to follow these guidelines may
result in injury or property damage.
WARNING!
This unit must be powered by a 24-hour, 120VAC 60Hz
circuit. Be sure the circuit cannot be turned off by a
switch, dimmer, or ground fault circuit interrupter.
Failure to connect this unit to a 24-hour circuit may
prevent it from providing constant protection
.
WARNING!
This alarm must have AC or battery power to operate. If
the AC power fails, battery back-up will allow the alarm
to sound for at least 4 minutes (if the battery is weak,
protection should last for up to 7 days.) If AC power
fails and the battery is dead or missing, the alarm
cannot operate.
WARNING!
It is possible an electrical fire could occur on the
circuit powering this unit. If this happened, the power
to the unit could be cut off and it may fail to alarm.
Some safety experts recommend wiring warning
devices like this unit on separate circuits from other
appliances, since these circuits are not as likely to be
overloaded. Other safety experts recommend wiring
these units on the same circuits as appliances so it is
more readily apparent if the circuit fails. Whichever
circuit you choose, it is recommended you also install
battery powered units as back-ups in case of fire on
the circuit powering the AC powered units.
WARNING!
Never disconnect the power from an AC powered unit
to stop an unwanted alarm. Doing so will disable the
unit and remove your protection. In the case of a true
unwanted alarm open a window or fan the smoke
away from the unit. The alarm will reset automatically
when it returns to normal operation. Never remove the
batteries from a battery operated unit to stop an
unwanted alarm (caused by cooking smoke, etc.).
Instead open a window or fan the smoke away from
the unit. The alarm will reset automatically.
