TAMPER RESIST LOCKING PIN: To make your smoke alarm tamper resistant, a
locking pin has been provided with your alarm. Using this pin will help deter
children and others from removing the alarm from trim ring. To use the pin,
insert it into the hole in the side of the alarm after the alarm has been installed
on the trim ring (see figure 8). NOTE: The tamper resist pin will have to be
removed in order to change the batteries. Use long nose pliers to pull the pin
out of the hole. It is now possible to remove the alarm from the trim ring.
After installation, TEST your alarm by pressing and holding the test/hush button
for several seconds. This should sound the alarm and activate the Safety Light.
4. OPERATION AND TESTING
OPERATION: The smoke alarm is operating once AC power is applied, fresh bat-
teries are installed and testing is complete. When the smoke alarm ionization
chamber senses products of combustion, the horn will sound a loud (85db) tem-
poral alarm until the sensing chamber is cleared of smoke particles.
HUSH
TM
CONTROL: The “HUSH” feature has the capability of temporarily desen-
sitizing the alarm circuit for up to 8 minutes. This feature is to be used only
when a known alarm condition, such as smoke from cooking, activates the
alarm. The smoke alarm is desensitized by pushing the “TEST / HUSH” button
on the smoke alarm cover. If the smoke is not too dense, the alarm will silence
immediately. The red LED will illuminate for 1.5 seconds every 8-10 seconds
while in hush. This indicates that the alarm is in a temporarily desensitized con-
dition. The smoke alarm will automatically reset after approximately 8 minutes
and sound the alarm if particles of combustion are still present. The “HUSH”
feature can be used repeatedly until the air has been cleared of the condition
causing the alarm. Pushing the Test / Hush button on the alarm will end the
hush period.
