Interconnected CO alarms or CO alarm circuit of combination smoke and CO and Natural Gas alarms will only respond if a CO alarm / event initiates the alarm. All other alarms remain silent. 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 smoke alarms without battery backup will not respond during an AC power failure. NOTE: Relay Modules/USI-960 will not respond if a CO alarm / event initiates the alarm. Page 8 The yellow wire is used only for multiple station operations with USI ELECTRIC or UNIVERSAL Model alarms only. Connecting this yellow wire to any other circuits may result in damage and alarm malfunction. When alarms are interconnected, all alarms 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 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) 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/NFPA70. In addition, the resistance of the interconnecting wiring shall be a maximum of 10 Ohms. 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. Confirm 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 7. 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. IMPORTANT! The battery backup is designed to provide short-term emergency power to the CO and Gas Alarm. Actual backup time depends on the strength (freshness) of the battery. The battery backup will not work unless a good battery is properly installed. When the alarm utilizes battery backup power, the natural gas sensor will operate the alarm and will sample less frequently to extend battery life. Natural gas could be present during this period between samples without the alarm sounding, especially if there is a rapid buildup of natural gas. OPERATION, TESTING & MAINTENANCE OPERATION: The 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. LOW BATTERY ALARM: If the alarm chirps once approx. every 40 seconds, please verify that the battery activation pull tab has been completely removed, the battery polarity is correct and the battery terminals are making contact with the alarm contacts in the battery compartment. If the battery continues to chirp, replace the 9 volt battery. 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 SMOKE ALARM CONDITION: The red LED blinks on approx. every 2 seconds and the alarm emits a loud, pulsating alarm sound. NON-ORIGINATING SMOKEALARM 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. CO ALARM: The alarm signal is 4 beeps, 2 second pause, repeat. The green LED turns off when the 4 beeps start. The red LED blinks in sync with the cycle of 4 beeps. GAS ALARM: The alarm signal is 1 beep, 1 second pause, repeat. The green LED blinks off. The blue LED blinks in sync with the horn beep every second. NUISANCE ALARM: If the horn signals for no apparent reason and no obvious hazard is present, please verify that the alarm is mounted in the correct location. Reset the alarm as instructed in the Operational Summary. Page 9 SMOKE ALARM LATCHING LED INDICATOR: The alarm had prevously detected smoke and had alarmed. The red LED is off and blinks on every 5 seconds until reset. Follow the reset instructions to remove the latching LED. CO ALARM LATCHING LED INDICATOR: The alarm had previously detected CO and had alarmed. The red LED is off and blinks on every 5 seconds until reset. Follow the reset instructions to remove the latching LED. GAS ALARM LATCHING LED I...
