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 alarm does not detect gas, heat or flame,
and should not be covered with a guard or similar obstructing item.
This smoke alarm may not alert people who are hearing impaired. It is strongly recommended
that the special-purpose smoke alarms using visual or vibrating alerting devices, should be
installed for these occupants.
This smoke alarm may not be effective in fires where smoke 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 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.
Features
ZT-MS AC/DC smoke alarms provide smoke detection and alarm functions
within a single unit. Advanced electronics in conjunction with a photoelectric
smoke sensing chamber provide early detection of smoke and high immunity
against unwanted alarms.
ZT-MS AC/DC smoke alarms are mains powered, with battery backup, suitable
for general residential applications. ZT-MS AC/DC smoke alarms provide home
owners and installers with an easy-to-install, premium solution for life safety and
property protection applications.
Audible and Visual Alarm Indicators
When operating normally, a green LED in the Test button illuminate. When
smoke is detected, an internal sounder will activate to alert occupants, and a
red LED will flash rapidly. The sounder is a loud, pulsating alarm.
Test Button
Pressing and holding the Test button for 3 s will activate the smoke alarm to
check its operation. The alarm will sound and the red LED will flash rapidly.
Releasing the test button will return the unit to normal operation.
Low Battery
When the battery is depleted, the smoke alarm will emit a short audible 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.
Smoke chamber fault
When the smoke chamber is degraded or contaminated over a limit, the smoke
alarm will emit two short audible signals every 48 s, while the red LED not
flashes simultaneously. When the smoke chamber 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 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 to clear. During the hush time, the red LED will flash once
every 6 s. After the Hush time has expired, the smoke alarm will return to
normal sensitivity. If smoke 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 alarms will activate sounders on all units if any smoke
alarm detects smoke. In this case, only the smoke alarm(s) that detected smoke
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.

approved single- and multiple-station smoke alarms shall be installed as follows:
(1) *In all sleeping rooms and guest rooms
(2) *Outside of each separate dwelling unit sleeping area, within 6.4 m (21 ft.) of any door
to a sleeping room, the distance measured along a path of travel
(3) On every level of a dwelling unit, including basements
(4) On every level of a residential board and care occupancy (small facility), including
basements and excluding crawl spaces and unfinished attics
(5) *In the living area(s) of a guest suite
(6) In the living area(s) of a residential board and care occupancy
For complete coverage, smoke alarms should be installed in all rooms, halls,
storage areas, basements, and attics in the dwelling. The minimum coverage
is one smoke alarm on each floor and one outside each sleeping area. Please
use the following location guide.
Single Storey Dwellings
Install a smoke alarm in the hallway outside every separate bedroom area, as
shown in Fig. 1 a). Two smoke alarms should be installed in dwellings with two
bedroom areas, as shown in Fig. 1 b).
