Cat. 4120SB Only—
Using The Silence Feature
The silence feature on this unit can temporarily quiet
an unwanted alarm for several minutes.
CAUTION !
The silence feature does not disable the unit—it
makes it temporarily less sensitive to smoke. For
your safety, if smoke around the unit is dense
enough to suggest a potentially dangerous
situation, the unit will stay in alarm or may re-alarm
quickly. If you do not know the source of the
smoke, do not assume it is an unwanted alarm.
Not responding to a fire can result in property loss,
injury, or death.
IMPORTANT!
While the unit is in the “silence mode,” the test
button will not operate. The alarm cannot be tested
while in the silence mode.
To silence smoke alarms
in an interconnected series:
1. To silence multiple alarms in an interconnected
series, you must press the silence button on the
unit(s) that triggered the alarm.
NOTE:
The red light under the silence button on the initiating
alarm will flash rapidly. The red light will be off on all
other smoke alarms.
2. Once you activate the silence feature, you will
hear a reminder “chirp” on the initiating alarm
about once a minute (for up to 15 minutes).
3. While the units are in the “silence mode,” the test
buttons will not operate. The alarms cannot be
tested while in the silence mode.
4. The “chirping” on the initiating alarm will stop
once the unit returns to normal operation.
IMPORTANT!
The silence feature on these units can temporarily
quiet an unwanted alarm fo several minutes. To use
this feature, press the “Push to Silence” button on
the cover. Once you activate it, you will hear a
reminder “chirp” about once a minute (for up to 15
minutes) and the Test feature is temporarily

returns to normal operation. If the unit will not
silence and no heavy smoke is present, or if it
stays in silence mode continuously, it should be
replaced immediately.
