Cautions

ELECTRICAL HAZARD: Disconnect power from equipment prior to making any
internal adjustments. Installation and service should only be performed by qualified
personnel.
PRODUCT LIMITATIONS: This smoke & heat alarm does not detect gas, or flame,
and should not be covered with a guard or similar obstructing item.
This smoke & heat alarm may not alert people who are hearing impaired. It is strongly
recommended that the special-purpose smoke & heat alarms using visual or vibrating alerting
devices, should be installed for these occupants.
This smoke & heat alarm may not be effective in fires where smoke and heat is prevented
from reaching the device (eg where intermediate doors are closed), where the fire grows so
rapidly that the egress path is blocked (even when correctly located), and where the fire is
intimate to a person (eg where a victim's clothes catch fire).
SLEEPING OCCUPANTS: Studies have shown that smoke & heat alarms may not
awaken all sleeping occupants, and it is the responsibility of individuals in the
household that are capable of assisting other to provide assistance to those who may be
awakened by the alarm sound, or to those who may be incapable of safely evacuating the
area unassisted.
INSTALLATION LIMITATIONS This product is designed for use in a single
residential unit, such as a family home or apartment. It should only be used in
lobbies, hallways, basements etc. if interconnected with other compatible smoke or heat
alarms. Smoke alarms, located outside the dwelling may not provide early warning to
occupants.
This product is not designed for use in non-residential buildings. Non-residential buildings
require special fire detection and alarm systems. This product alone is not a suitable
substitute for a fire detection system installed in places of work or where people sleep on a
temporary basis, such as hotels or motels, dormitories, hospitals, nursing homes or group
homes of any kind, even if they were once dwellings. Please refer to local regulations for fire
detection and alarm system requirements.

signal every 48 s for at least 30 days, while the red LED flashes simultaneously.
When the Low Battery signal is given, change the battery without delay.
Suitable for

Fault

Leisure
Accommodation
When the smoke chamber is degraded or contaminated over a limit or the
Vehicles (LAV)
thermistor is damaged, the smoke & heat alarm will emit two short audible
Yes signals every 48 s, while the red LED not flashes simultaneously. When the fault
is given, try vacuum the product on the outer surface, especially the smoke inlet,
to remove dirt. If the condition persists, return the product for service.
Hush Button
Pressing the Hush button will reduce the sensitivity of the smoke & heat alarm
for approximately 10 min. The Hush button should only be used after the cause
of the alarm is known (such as normal cooking fumes). The Hush feature
allows time for the smoke/heat to clear. During the hush time, the red LED will
flash once every 6 s. After the Hush time has expired, the smoke & heat alarm
will return to normal sensitivity. If smoke/heat is still present in the unit, the
alarm will re-activate. The Hush feature can be used repeatedly.
Under hush mode, press the hush button again will return the unit to normal
operation.

Alarm Memory

Alarm Memory feature allows easy identification of any unit that has previously
been in the Alarm condition. If a unit enters the Alarm condition and
subsequently returns to the Normal condition, the Alarm Memory is set. Initially,
the red LED will flash three times every 48 s. In order to preserve battery
power, this visual indication will stop after 24 hours and the unit will return to
Normal Operation.
If the Alarm Memory is active, pressing and releasing the Test/Hush button
resets the Alarm Memory with 3 short beeps.

Interconnection Terminals

Interconnected smoke & heat alarms will activate sounders on all units if any
smoke & heat alarm detects smoke/heat. In this case, only the smoke & heat
alarm(s) that detected smoke/heat will flash the red LED indicator. This allows
the home owner to quickly locate the cause of the alarm. Up to 24 units can be
interconnected as long as the cabling is less than 250 m in length.
