15 | ELECTRICAL SHOCK HAZARDS
WARNING: PLEASE READ CAREFULLY AND THOROUGHLY
1. Before beginning installation, turn off power to the area where you will install your Halo. Failure to turn off
the power before installation may result in electrical shock, serious injury, or death.
2. Improper wiring of the power connector or the wiring leading to it will cause damage to the alarm and may
lead to a non-functioning alarm. Removing the alarm without turning off the power will also cause
damage/may lead to a non-function alarm.
3. Do not restore power until all alarms are completely installed. Restoring power before completing
installation may result in serious electrical shock, injury, or death.
4. If any unit does not alarm, TURN OFF POWER and recheck connections. If it does not alarm when you
restore power, contact Halo customer service at (888) 434-HALO (4256) immediately.
5. Attempting to disconnect the power connector from the unit when the power is on may result in electrical
shock, serious injury, or death.
6. This unit must be powered by a 24-hour, 120V AC sine wave, 60Hz 0.1A circuit. Be sure the circuit cannot
be turned off by a switch, dimmer, or ground fault circuit interrupter.
7. Never disconnect the power from an AC-powered unit to stop an unwanted alarm. Instead, open a window
or fan the smoke away from the unit. The alarm will reset automatically when it returns to normal operation.
16 | CALIFORNIA STATE FIRE MARSHALL
As stated by the California State Fire Marshal, “Early warning fire detection is best achieved by the installation
of fire detection equipment in all rooms and areas of the household as follows: a smoke alarm installed in each
separate sleeping area (in the vicinity of, but outside of the bedrooms), and heat or smoke detectors in the
living rooms, dining rooms, bedrooms, kitchens, hallways, attics, furnace rooms, closets, utility and storage
rooms, basements and attached garages.”
17 | NUCLEAR REGULATORY COMMISSION (NRC) INFORMATION
Ionization smoke alarms use a very small amount of a radioactive element in the sensing chamber to enable
detection of visible and invisible combustion products. The radioactive element is safely contained in the
chamber and requires no adjustments or maintenance. This smoke alarm meets or exceeds all government
standards. It is manufactured and distributed under license from the U.S. Nuclear Regulatory Commission.
