maximum recommended cable resistance is 20 ohms. All
wiring must comply with local codes. Screw unit to ceiling
using screws provided. Put cover back on the Smoke Alarm
by matching up hinges and gently snapping it on to the base.
Caution:
(a) The Smoke/Heat Alarm must be wired to a 12V supply
that is permanently on.
(b) Positive air pressure at wiring openings, conduit or
mounting boxes/holes can cause draughts through and away
from the Smoke/Heat Alarm which may prevent correct
operation. Any such openings must be sealed (with silicone
rubber or similar) to prevent unwanted air movement.
Interconnecting Smoke Alarms and Heat Alarms
When a fire is sensed the alarm must be given throughout the
house. Up to twelve (12) Smoke Alarms (models Ei100R3,
Ei105R3 & Ei105R4 only) and Heat Alarms (model Ei103R
only) can be interconnected so that when one senses fire all
alarm. Do not interconnect to any other type of alarm. The unit
initiating the alarm can be identified by its LED flashing every
second. Figure 6 shows the interconnect wiring.
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.
