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 alarms in living rooms,
dining rooms, kitchens, hallways, attics, furnace rooms, closets, utility
storage rooms, basements and attached garages. Test the heat or smoke
alarm weekly to assure proper operation.
3. Attach the mounting ring to the electrical junction box.
4. To activate 9 volt battery and heat alarm, pull and remove the thin colored plastic
tab at battery door hinge. Discard plastic tab.
5. Plug the AC QUICK CONNECTORS together. Push and turn the heat alarm clockwise
onto the mounting ring.
6. See "TAMPER LOCKING PIN."
7. Turn on AC power and check the LED's for proper operation. The green LED lights to
indicate AC power. The red LED will flash every 40-60 seconds to indicate proper
operation.

Interconnected combination Natural Gas Alarms will only respond if a
natural gas event initiated the alarm. All other alarms remain silent.
Interconnected smoke alarms, heat alarms and relay modules will only
respond if a smoke alarm / event or heat alarm / event initiates the alarm.
All CO and Natural Gas alarms remain silent.
Note that alarms without battery backup will not respond during an AC power
failure.
NOTE: Relay Modules/USI-960 will not respond if a CO or Natural Gas
alarm / event initiates the alarm.
The yellow wire is used only for multiple station operation with USI Models
only. Connecting this yellow wire to any other circuits may result in damage.
When heat alarms are interconnected, all units must be powered from a
single AC branch circuit. If local codes do not permit be sure the neutral
wire is common to both phases. The maximum wire run distance between
the first and last heat alarm in an interconnected system is 1,000 feet.
NOTE: Use standard household wire (18 gauge or larger, rated at least 300V,
as required by local codes) available at all electrical supply/hardware
stores.
The wiring to be used shall be in accordance with the provisions of Articles
210 and 300.3(B) of the National Electrical Code, ANSI/NFPA 70. In addition,
the resistance of the interconnecting wiring shall be a maximum of 10
Ohms.
