POSITIONING SMOKE/HEAT ALARMS
The locations must comply with applicable building
regulations.
Hot smoke rises and spreads out, so a central ceiling
position is the preferred location. The air is "dead" and does
not move in corners, therefore Smoke & Heat Alarms must
be mounted away from corners. Place the unit at least
300mm (12 inches) from any light fitting or decorative object
which might obstruct smoke / heat entering the Alarm.
Keep at least 300mm (12") away from walls. See figure 4.
(Smoke Alarms should be located directly on the ceiling or
up to 570mm below it. Heat Alarms should be located
directly on the ceiling or up to 90mm below it).
Wall mounting is not recommended for these Alarms.
Sloping Ceiling
In areas with sloping or peaked ceilings install your Smoke/
Heat Alarm 90mm (3 feet) from the highest point measured
horizontally (see figure 5), because "dead air" at the apex
may prevent smoke from reaching the unit.
INTERCONNECTING SMOKE/HEAT
ALARMS
When a fire is sensed the alarm must be given throughout
the house. Up to twenty (20) Smoke Alarms (models Ei181,
& Ei186 only) and Heat Alarms (model Ei184) can be
interconnected so that when one senses fire all alarm.
Caution: Do not interconnect to any other type of alarm.
The unit initiating the alarm can be identified by the red LED
on the cover flashing every second. Figure 6 shows the
interconnect wiring.
Note: It is only necessary to wire one relay to the control
panel. If any alarm senses fire this relay will change state
due to the signal on the interconnect line.
These Alarms should be interconnected only within the
confines of a single family living unit. If they are
interconnected between different units there
may be
excessive nuisance alarms. Everybody may not be aware
that they are being tested or that it is a nuisance alarm
caused by cooking etc. When one unit alarms all relays will
switch.
