OPERATION, TESTING & MAINTENANCE
OPERATION: The smoke alarm is operating once the AC power is connected and turned on (the
battery must also be installed). When products of combustion are sensed, the alarm sounds a loud
alarm which continues until the air is cleared.
This alarm incorporates the NFPA recognized horn signal for evacuation. During alarm mode, the
horn produces three beeps followed by a two second pause and then continually repeats.
READY/ACTIVE CONDITION: The red LED blinks on once approx. every 40-45 seconds to indicate
the alarm is properly functioning.
LOCAL ORIGINATING ALARM CONDITION: The red LED blinks on approx. every 2 seconds and
the alarm emits a loud, pulsating alarm sound.
NON-ORIGINATING ALARM CONDITION: The red LED is off and the alarm emits a loud, pulsating
alarm.
GREEN LED: The green LED is on whenever AC power is turned on.
Interconnected smoke alarms, heat alarms and relays will only respond if a smoke alarm
event or heat alarm event initiates the alarm. All CO and natural gas alarms remain silent.
NOTE: Alarms without battery backup will not respond during an AC power failure.
NOTE: The relay, model USI-960, will not respond if a CO or natural gas alarm event initiates
the alarm.
The yellow wire is used only for interconnect (multiple station operations) USI Electric or
Universal model alarms. Connecting this yellow wire to any other circuits may result in
damage and alarm malfunction. All interconnect alarms must be powered from a single circuit.
If local codes do not specify, be sure the neutral wire is common to all alarms. The maximum
wire run distance between the rst and last alarm/device 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. This wire is commonly available at most electrical supply and
hardware stores. The resistance of the interconnect wiring shall be a maximum of 10 Ohms.
The alarm wiring shall be in accordance with the provisions of Articles 210 and 300.3(B) of
the National Electrical Code, ANSI/NFPA 70. According to the NFPA 72 / Ed. 2013; paragraph
29.6.3 Household Fire Alarm Systems /AC Primary Power Source: “AC primary (main)
power shall be supplied either from a dedicated branch circuit or the un-switched portion
of a branch circuit also used for power and lighting.”.
2. Attach the mounting bracket to the electrical junction box.
3. To activate 9 volt battery and alarm, hold the Quick Draw
(R)
battery drawer closed, pull and
remove the pull-tab. Conrm that the entire pull-tab has been completely removed. Discard
pull-tab.
4. Plug the AC quick connector into the alarm base. Push and twist the alarm clockwise onto the
mounting bracket.
5. See "Optional Tamper Resistant Features" and "To Activate the Locking Features" instructions
on Page 4.
6. Turn on AC power and check the LED's for proper operation. The green LED should be on to
indicate AC power. The red LED blinks on once approx. every 40 seconds to indicate proper
operation.
