First Alert HD6135FB - Manual (Page 3)

The basic installation of this Heat Alarm is the similar whether you want to
install one Heat Alarm, or interconnect more than one Heat Alarm. If you
are interconnecting more than one Heat Alarm, you MUST read “Special
Requirements for Interconnected Heat Alarms” below before you begin
installation.
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.
1. Remove the mounting bracket from the base. Position the screw slots
on the mounting bracket over the screws in the junction box. Tighten
the screws.
2. Using wire nuts, connect the power connector to the household wiring.
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.
3. Plug the power connector into the back of the Heat Alarm.
4. Position the base of the Alarm over the mounting bracket and turn. The
Alarm can be positioned over the bracket every 60°. Turn the Alarm
clockwise (right) until the unit is in place.
5. Check all connections.
ELECTRICAL SHOCK HAZARD. Do not restore power until all Heat
Alarms are completely installed. Restoring power before installation is
complete may result in serious electrical shock, injury or death.
6. Make sure the Heat Alarm is receiving AC power. Under normal
operation, the green light (LED) will shine continuously.
7. If the green power indicator light does not light, TURN OFF POWER TO
THE JUNCTION BOX and recheck all connections. If all connections are
correct and the power indicator still does not light when you restore the
power, the unit should be replaced immediately.
8. Test each Heat Alarm. Press the Test/Silence button until you hear a brief
acknowledge (or feedback) chirp. The alarm will sound: 3 beeps, pause,
3 beeps, pause.
When testing a series of interconnected units you must test each
unit individually. Make sure all units alarm when each one is tested.
If any unit in the series does not alarm, TURN OFF POWER and recheck
connections. If it does not alarm during testing when you restore power,
replace it immediately.
SPECIAL REQUIREMENTS FOR INTERCONNECTED HEAT ALARMS
• Failure to meet any of these requirements could damage the units
and cause them to malfunction, removing your protection.
Interconnected units can provide earlier warning of fire than stand-alone
units, especially if a fire starts in a remote area of the dwelling. If any unit
in the series senses heat, all units will alarm.
Interconnect units within a single family residence only. Otherwise all house-
holds will experience unwanted alarms when you test any unit in the series.
Interconnected units will only work if they are wired to compatible units and
all requirements are met. This unit is designed to be compatible with:
First Alert
® Smoke Alarm Models SA4120, SA4121B, SA4919B, SA100B
and BRK Electronics ® Smoke Alarm Models 100S, 2002RAC, 4120, 4120B,
4120SB, 4919, 5919, 5919TH; BRK Electronics ® Smoke/CO Alarm Model
SC6120B.
Interconnected units must meet ALL of the following requirements:
• A maximum of 18 compatible Smoke, Heat or CO Alarms may be
interconnected. To comply with NFPA limits, no more than 12 of the
18 alarms may be Smoke Alarms.
• The same fuse or circuit breaker must power all interconnected units.
• All wiring must conform to all local electrical codes and NFPA 70 (NEC).
Refer to NFPA, Chapter 2 and/or your local building code for further
connection requirements.
FOLLOW THESE INSTALLATION STEPS
STAND-ALONE ALARM ONLY:
• Connect the white wire on the power connector to the neutral wire in
the junction box.
• Connect the black wire on the power connector to the hot wire in the
junction box.
• Tuck the orange wire inside the junction box. It is used for
interconnect only.
INTERCONNECTED UNITS ONLY:
Strip off about 1/2” (12 mm) of the plastic coating on the orange
wire on the power connector.
• Connect the white wire on the power connector to the neutral wire in
the junction box.
• Connect the black wire on the power connector to the hot wire in the
junction box.
• Connect the orange wire on the power connector to the interconnect
wire in the junction box. Repeat for each unit you are interconnecting.
Never connect the hot or neutral wires in the junction box to the orange
interconnect wire. Damage may result.
• Never cross-connect hot and neutral wires between interconnected
Alarms. Damage will result.
STAND-ALONE ALARM ONLY:
• If you are only installing one Heat Alarm, restore power to the
junction box.
INTERCONNECTED UNITS ONLY:
• If you are interconnecting multiple Heat Alarms, repeat steps 1-5
for each Heat Alarm in the series. When you are finished, restore
power to the junction box.
