In the event of a smoke alarm activation, do not use the Silence feature until the 

source of the alarm has been identified and safe conditions exist. 

The Silence feature is intended to temporarily silence the horn while identifying and correct-

ing the problem. To use the Silence feature, press and release the test/silence button until the 

horn is silent if it was the initiating alarm. If the test/silence button is pressed while the alarm 

is in the silence mode, the alarm will start sounding again.

The CO alarm Silence feature 

can be activated by a press and release of the test/silence 

button on the initiating alarm while in alarm condition. The alarm will remain silent for ap-

proximately 5 minutes, depending on the level of CO detected.   The red CO LED will blink 

on approximately every 10 seconds.  If CO levels drop below the alarm levels, the alarm will 

remain silent and return to normal operation. If CO levels remain constant or increase, the 

alarm will sound again.  This indicates a potentially dangerous situation. Ventilate the area. 

The smoke alarm Silence feature

 can be activated by press and release of the test/silence 

button on the initiating alarm while in alarm condition. The alarm will remain silent for approx-

imately 8-12 minutes, depending on the level of smoke detected. The red smoke LED will 

blink on approximately every 10 seconds. If smoke levels have not cleared during the silence 

period, the alarm will sound again. This indicates a potentially dangerous situation. Ventilate 

the area. If the alarm remains silent, the smoke levels have dropped and the alarm will return 

to normal operation. If smoke levels remain constant or increase, the alarm will sound again. 

 

TESTING INSTRUCTIONS

  NEVER use an open flame of any kind to test this alarm.

 You may 

accidentally damage or set fire to the alarm or to your home. 

NEVER use vehicle exhaust to test the alarm! 

Exhaust may cause permanent damage 

and voids the warranty.

NEVER use a gas range or an open flame of any kind to test this alarm.

 You might  

accidentally damage or set fire to the alarm or to your home.

CAUTION:

 Continuous exposure to the high sound level of this alarm over an extended 

period of time may cause hearing loss. Due to the loudness, we suggest that you place your 
fingers over the sounder opening, or step back from the alarm while testing.    

NOTE: 

 The alarm horn loudness meets or exceeds current UL standards of 85 dB at 10 feet 

(3 meters).

WEEKLY TESTING:

 This alarm is designed to act as a monitor, not for use as a short-term 

testing device, or to perform a quick check for the presence of CO or smoke. The built-in test 

switch accurately tests the alarm operation as required by ANSI/UL 2034/UL 217 Standards 

for Safety. If at any time the alarm does not perform as described when tested, replace it 

immediately.  Weekly testing is required to ensure proper operation. Irregular or low volume 

sound may indicate a defective alarm and it should be returned for service. Follow deactiva-

tion instructions to prepare alarm for shipment or disposal.

USING THE TEST FEATURE:

Press and release the Test button on the alarm cover. During 

testing, the alarm will sound a loud horn pattern consisting of 3 beeps, followed by a 6 

second pause, then 4 beeps.  The green LED will be on and the red smoke LED will blink in 

sync with the 3 beeps and the red CO LED will blink in sync with the 4 beeps.  The alarm will 
sound if all the electronic circuitry, horn and battery are working properly.
In an interconnected installation, all interconnected alarms should sound when the test button 
is pressed on any one of the alarms.
If the alarm does not sound properly:
1. Disconnect the power and recheck your wiring and connections. Restore power and re-test.
2. Check the fuse or circuit breaker supplying power to the alarm circuit.
3. Hold the test button down longer. Try holding the test button down for up to 10 seconds.
4. Make sure the battery activation pull tab has been completely removed.
5. If there is still a problem, call customer service.  Do not attempt to fix the alarm.
