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 households 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 Article 760 of the National Electrical Code. Refer
to NFPA, Chapter 2 and/or your local building code for further connection requirements.

LOCKING FEATURES
The locking features are designed to discourage unauthorized removal of the battery or alarm. It is
not necessary to activate the locks in single-family households where unauthorized battery or alarm
removal is not a concern.
These Heat Alarms have two separate locking features: one to lock the battery
compartment, and the other to lock the Heat Alarm to the mounting bracket.
You can choose to use either feature independently, or use them both.
Tools you will need: • Needle-nose pliers or utility knife
• Standard/Flathead screwdriver.
Both locking features use locking pins, which are molded into the mounting
bracket. Using needle nose pliers or a utility knife, remove one or both pins from
the mounting bracket, depending on how many locking features you want to use.
To permanently remove either lock insert a flathead screwdriver between the locking pin and the lock,
and pry the pin out of the lock.
Locking Pin
TO LOCK THE BATTERY COMPARTMENT
Do not lock the battery compartment until you have activated the battery and tested the battery
back-up.
1. Activate the battery back-up by removing the “Pull to Activate Battery Back-Up”
tab.
DO NOT remove the battery activation until AC power is turned on to conserve
battery power.
2. Press the Test/Silence button until you hear a brief acknowledge (or feedback) chirp.
The alarm will sound: 3 beeps, pause, 3 beeps, pause.
If the unit does not alarm during testing, DO NOT lock the battery
compartment! Install a new battery and test again. If the Heat Alarm
still does not alarm, replace it immediately.
3. Using needle-nose pliers or a utility knife, detach one locking pin
from the mounting bracket.
4. Push the locking pin through the black dot on the label on the
back of the Heat Alarm.
TO UNLOCK THE BATTERY COMPARTMENT
Once the Heat Alarm is installed, you must disconnect it from the AC power before unlocking the battery
compartment.
ELECTRICAL SHOCK HAZARD. Turn off the power to the area where the Heat 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.
Turn off the AC power at the circuit breaker or fuse box.
1. Remove the Heat Alarm from the mounting bracket. If the unit is locked to the bracket, see the section
“To Unlock the Mounting Bracket.”
2. Disconnect the power connector by gently prying it away from the
back of the Heat Alarm.
3. Insert a flathead screwdriver under the head of the locking pin,
and gently pry it out of the battery compartment lock. (If you plan
to relock the battery compartment, save the locking pin.)
4. To relock the battery compartment, close the battery door and
reinsert locking pin in lock.
5. Reconnect the power connector to the back of the Alarm, reattach
the Heat Alarm to the mounting bracket, and restore the power.
When replacing the battery, always test the Heat Alarm before relocking the battery compartment.
