How to install this smoke/co alarm

120VAC Installations

This Smoke/CO Alarm is designed to be mounted on any standard wiring junction box up to a 4-inch (10 cm) size, on either the ceiling or wall (if allowed by local codes). Read “Where To Install This Alarm” and “Where Not To Install This Alarm” in the Regulatory Guide before you begin installation. NOTE: Mount the alarm flush to the electrical box to eliminate air leaks between the ceiling surface and the mounting bracket.

Tools you will need: • Needle-nose pliers or utility knife • Standard flathead screwdriver • Wire strippers.

DANGER!

ELECTRICAL SHOCK HAZARD

Turn off the power to the area where the Alarm is installed before removing it from the mounting bracket. Failure to turn off the power first may result in serious electrical shock, injury or death.

Electrical Wiring Best Practices for BRK Alarms in New Construction

The basic installation of this Alarm is similar whether you want to install one Alarm, or interconnect more than one Alarm. If you are interconnecting more than one Alarm, you MUST read “Special Requirements for Interconnected Alarms” before you begin installation.

NOTE: Install in accordance with installation instructions, applicable codes and ordinances and in a manner acceptable to the authority having jurisdiction. Check with your local Fire Department for current requirements in your area.

IMPORTANT:

  • Never connect the hot or neutral wires in the junction box to the orange interconnect wire. Never cross hot and neutral wires between Alarms.

  • Improper wiring of the power connector or the wiring leading to the power connector will cause damage to the Alarm and may lead to a non-functioning Alarm.

  • Make sure the Alarm is not receiving excessively noisy power. Examples of noisy power could be major appliances on the same circuit, power from a generator or solar power, light dimmer on the same circuit or mounted near fluorescent lighting. Excessively noisy power may cause damage to your Alarm.

NOTES:

  • If using the models with replaceable batteries, install them. Battery back-up cannot work until you install the battery in the correct position (Match “+” to “+” and “-” to “-”).

  • In step six, activation is a one time use only.

STAND-ALONE ALARM ONLY:

  • If you are only installing one Alarm, restore power to the junction box.

INTERCONNECTED UNITS ONLY:

  • If you are interconnecting multiple Alarms, repeat steps 1-6 for each Alarm in the series. When you are finished, restore power to the junction box.

NOTES:

  • Make sure the Alarm is receiving AC power. Under normal operation, the Green power indicator light will shine continuously.

  • Test each Smoke Alarm. Press and hold the Test/Silence button until the unit alarms. When testing a series of interconnected units you must test each unit individually. Make sure all units alarm when each one is tested.

DANGER!

If any unit in the series does not alarm, TURN OFF POWER and recheck connections. If it does not alarm when you restore power, replace it immediately.
