HUSH BUTTON
Models KF10, KF10LL, KF10R, KF20, KF20LL and KF20R feature Hush Button
that, when activated, quiets unwanted alarms for up to 9 minutes.
To use the Hush Button:
Press and release the test button during an unwanted alarm. The alarm
should stop within ten seconds. This means the smoke alarm is in Hush
Button. If the smoke alarm does not go into Hush and continues to sound
its loud alarm horn, or if it initially goes into Hush then resounds the alarm,
the smoke is too heavy and could be a dangerous situation – take
emergency action.
TESTING THE SMOKE ALARM
W A R N I N G
•
Test each smoke alarm to be sure it is installed correctly and operating
properly.
•
Test all smoke alarms in an interconnected system after installation.
•
The Push-to-Test button accurately tests all functions. DO NOT use an
open flame to test this smoke alarm. You may ignite and damage the
smoke alarm or your home.
•
Test smoke alarms weekly and upon returning from holiday or when no
one has been in the household for several days.
•
Stand at arm’s length from the smoke alarm when testing. The alarm
horn is loud to alert you to an emergency and can be harmful to hearing.
Test all smoke alarms weekly by doing the following:
1. Check Push-to-Test button. A constant green light indicates the smoke
alarm is receiving 230V AC, 50Hz power. A red flashing LED about once
every 5 minutes verifies operation. For models KF10, KF10LL, KF10R,
KF20, KF20LL and KF20R the red flashing LED also verifies that a
working battery is present.
2. Firmly depress and hold the Push-to-Test button for at least five (5) sec-
onds. The smoke alarm will sound a loud beep about three (3) times a
second. The alarm may sound for up to 10 seconds after releasing the
Push-to-Test button.
NOTE:
If smoke alarms are interconnected, all smoke alarms should
sound an alarm within three seconds after any test button is
pushed and the tested smoke alarm sounds.
3. If smoke alarm does not sound, turn off power at main fuse box or
circuit breaker and check wiring. Retest smoke alarm.
DANGER: If alarm horn sounds, and smoke alarm is
not being tested, the smoke alarm is sensing
smoke. THE SOUND OF THE ALARM HORN
REQUIRES YOUR IMMEDIATE ATTENTION
AND ACTION.
MAINTENANCE AND CLEANING
In addition to weekly testing, Models KF10 and KF20 also require periodic bat-
tery replacement. Regularly clean smoke alarm to remove dust, dirt, and
debris.
WARNING: Alarm comes equipped with a dust cover,
which prevents dust and debris from
damaging the unit during construction or
remodeling. Remove dust cover before oper-
ation. Alarm will not operate properly while
covered.
DANGER:
ELECTRICAL SHOCK HAZARD. Turn off main
power at fuse box or consumer unit by
removing fuse or switching appropriate circuit
breaker to OFF position before replacing
battery or cleaning smoke alarm.
