Install smoke alarms as close to the centre of the ceiling as possible. If this is not practical,
put the alarm on the ceiling, no closer than 300 mm from any wall and 600 mm from any
corner, as shown in Figure 4.
When mounting a smoke alarm on a wall, use an inside wall with the top edge of the
alarm a minimum of 300 mm and a maximum of 500 mm below the ceiling and at least
600 mm from any corner, as shown in Figure 4.
If your rooms have sloped, peaked, or gabled ceilings, smoke alarms must be installed
500 mm – 1500 mm, measured horizontally, from the highest point (apex) of the
ceiling as shown in Figure 5.
3. INSTALLATION LOCATIONS - CARAVANS AND MOBILE
HOMES
Many caravans and mobile homes may not be well insulated, enabling extreme heat or
cold to be transferred from outside through the walls and roof. This may create a thermal
barrier which can prevent smoke from reaching a smoke alarm mounted on the ceiling.
If this situation exists, install your smoke alarm on an inside partition between 300 mm
and 500 mm from the ceiling. If you are not sure but you notice the walls and ceilings are either hot or cold, install the alarm on an inside wall. For
minimum protection, install one alarm close to the bedrooms. For additional protection refer to the single residence plan (Figure 1).
In caravans and mobile homes, it is particularly important to install smoke alarms as far away as possible form cooking areas to reduce the potential
for nuisance alarms.
4. WHERE NOT TO INSTALL YOUR SMOKE ALARM
Installing a smoke alarm in an unsuitable location can create many problems. Obstructions may prevent the alarm from giving early warning in the
event of fire. Its location may also lead to nuisance (false) alarms. To avoid these potential problems, Exelgard PE series smoke alarms should not
be installed in any of the following locations:
The garage. Engine exhaust fumes may cause nuisance alarms.•
In front of forced air movement from air-conditioners, fans and heaters.•
In dead air spaces where smoke may not enter. Avoid installing alarms in the peak or upper sections of a sloping or ‘A’ framed ceiling, and•
between exposed ceiling beams, where the air does not circulate, see figure 5.
Dusty areas. Dust may cause a smoke alarm to false alarm or even fail.•
In spray painting areas.•
Where the temperature may fall below 4°C or rise above 38°C.•
In or near very humid areas such as bathrooms. Moisture can cause false alarms.•
Near hot water heaters, space heaters or fireplaces.•
In any area that attracts insects. Some lights attract insects, particularly fluorescent and mercury vapour lamps.•
Near fluorescent lights. Electrical “noise” from fluorescent lights may cause nuisance alarms. Install smoke alarms at least 1500 mm from•
such lights.
WARNING: Never remove the battery to stop a nuisance alarm. Open a window or fan the air around the alarm to get rid of the smoke. The alarm
will turn itself off when the smoke is gone.
WARNING: Do not stand close to the smoke alarm when the alarm is sounding. The alarm is loud in order to wake you in an emergency. Too much
exposure to the sounder at close range may be harmful to your hearing.
5. INSTALLING YOUR SMOKE ALARM
After reading the “INSTALLATION LOCATIONS” and “WHERE NOT TO INSTALL YOUR SMOKE ALARMS” section in these user instructions,
decide where to install your alarm.
Use the following steps to install your smoke alarm:
At the place where you are going to install the alarm, draw a line 150 mm long.1.
Remove the mounting bracket from your smoke alarm by rotating it counter-clockwise.2.
Place the bracket so that the two longest hole slots are aligned on the line. In each of the keyhole slots, draw a mark to locate a mounting plug3.
and screw.
Remove the bracket.4.
Using a 5 mm drill bit, drill two holes at the marks and insert a plastic wall plug in each hole. Note:5.
Move the smoke alarm away prior to drilling the holes to avoid contaminating the alarm with plaster
dust.
Attach the mounting bracket to the surface by inserting the screws supplied into the plastic wall6.
plugs.
Insert the battery supplied with the smoke alarm as follows:7.
WARNING: Do not connect the Exelgard PE series smoke alarms to any other alarm or auxiliary
device. Connecting anything else to this alarm will prevent it from working properly, and may void
the warranty.
Locate, on the reverse side of the smoke alarm, the recess provided to house the battery.a)
Match terminals on the end of the battery with opposite terminal connections, located in the recess on the alarm. Be sure to insert theb)
battery in the position shown on the alarm.
With the terminals correctly matched, push the battery firmly into the connectors until it snaps into place.c)
NOTE: When the battery first makes contact with the alarm connections, the alarm sounder may sound for one second. This is normal and indicates
that the battery is positioned properly.
NOTE: The battery is not fitted in the factory to keep it fresh until installation. It must be positioned correctly
to provide DC power.
Line up the slots/lugs of the mounting bracket and the alarm. Push the smoke alarm onto the8.
mounting bracket and turn it clockwise to fix it into place. Pull outwards on the alarm to make sure it
is securely attached to the mounting bracket.
CAUTION: This smoke alarm comes with cover latches that will prevent the smoke alarm from being
connected onto the mounting bracket if a battery is not fitted. This prevents an alarm without a battery
fitted from being installed.
Confirm that the smoke alarm is working correctly by pressing, and holding down for about 5 seconds, the test button on the front of the9.
smoke alarm until the alarm sounds. The alarm is a loud pulsating sound.
6. HUSH FEATURE
Where fitted, the hush feature is designed to temporarily silence the alarm from nuisance sources such as kitchen cooking fumes. Before using this
feature, fully identify the source of the smoke, make certain that the area is safe and that there is no fire.
The hush feature is to be used only when a known condition activates the alarm e.g. smoke from cooking.•
To operate, push the hush button once. The alarm will silence immediately and will hold in this mode for up to 15 minutes.•
When the 15 minutes has elapsed, the smoke alarm will automatically reset to the fully alert mode. If smoke is still present, the alarm will•
sound again.
The hush feature can be used repeatedly to silence the alarm until the air is cleared.•
Very dense smoke will override the hush feature and sound the alarm.•
7. LED INDICATOR
The small red light (or LED), is the alarm indicator. It can be seen through the test button on the cover. When the red LED flashes once every 32
seconds, it indicates the alarm is operating normally. When the smoke alarm senses smoke, and simultaneously sounds an audible alarm, the red
LED will flash rapidly, once every second.
8. TESTING YOUR SMOKE ALARM
Test the alarm weekly by pushing firmly on the test button with your finger until the alarm sounds. Testing method may take a few seconds to
sound the alarm. If the alarm fails to activate, replace the battery and repeat the test. If the alarm still fails to activate, have it replaced immediately.
WARNING: Never use an open flame to test your alarm. You may set fire to or damage the alarm, as well as your home. The built-in test switch
accurately tests all alarm functions.
WARNING: When you are not testing the unit and the alarm emits a loud continuous sound, the smoke alarm has sensed smoke or combustion
particles in the air. This indicates a possible serious situation, which requires your immediate attention.
