NOTE: DENSE SMOKE WILL OVERRIDE THE “HUSH®” CON-
TROL FEATURE AND SOUND A CONTINUOUS ALARM.
CAUTION: BEFORE USING THE ALARM “HUSH®” FEATURE,
IDENTIFY THE SOURCE OF THE SMOKE AND BE CERTAIN A
SAFE CONDITION EXISTS.
FLASHING LED LIGHT: This smoke alarm is equipped with a flash-
ing Red indicator light with three modes of operation:
Normal Operation
The LED flashing every 40 - 45 seconds indicates that the smoke
alarm battery is properly installed and the alarm is operating.
Alarm Mode / Originating Unit Indicator
The LED will Flash about every second when the alarm is sounding
(constant pulsating sound) as a result of the test button being acti-
vated or the smoke sensing chamber senses particles of combustion.
WHEN UNITS ARE INTERCONNECTED, Model 29HIJ only, the red
LED of the alarm that senses the smoke or is being tested (the
originating unit) will flash rapidly. All other units in the intercon-
nect system will sound an alarm but their red LED's will NOT flash
rapidly.
Hush® Mode.
The LED will Flash approximately every 1.5 seconds indicating the
alarm is in the "Hush®" mode.
SMOKE SENSING CHAMBER OPERATION: This alarm will "chirp" if
any of the components in the smoke-sensing chamber fail. This
chirp will occur between the normal standby flashes of the red
LED indicator light. (If the chirp occurs at the same time as the red
LED flash, this indicates a low battery, see section 6 for low battery
information.
ALARM MEMORY
This unit features an alarm memory to inform you that the alarm
has sounded since the test button was last pressed. If the alarm
memory is set the red LED will flash rapidly when the test button is
pressed. The alarm memory is reset when the test button is
released.
TESTING:
NOTE: WEEKLY TESTING IS REQUIRED!
CAUTION: Due to the loudness (85 decibels) of the alarm, always
stand an arms length away from the unit when testing.
