drill a hole through the centers of the marked locations. Push
the plastic Screw Anchors provided into the drilled holes. Screw
in firmly.
(b) Connecting the built-in Lithium battery
Push the power-on button (8), (see figure 6) until it clicks to
connect the battery permanently. Note: You may hear a loud
chirp when pressing the button. This is normal.
To close the cover match up the snap-in hinges (5) and gently
press together until they are attached. Press the test button (3)
- the horn should sound to show the Smoke Alarm is now
working. If the horn does not sound try pushing the power-on
button (8) again. Note: The power-on button cannot be used to
disconnect the battery.
5. Interconnecting your Smoke Alarm
A maximum of twelve Ei100TYC Smoke Alarms may be wired
together such that when one unit senses smoke all other units
sound a warning. This helps ensure smoke alarms will be
heard. (Model Ei100TY & Ei100TYK can not be
interconnected).
The Ei100TYC Ionisation Smoke Alarm may also be
interconnected to the Ei Optical Smoke Alarm, model number
Ei3105TYC.
Warning: Do not interconnect to any other Smoke Alarms
A maximum of 250 metres (820 feet) of wire can be used,
(maximum resistance between detectors 50 ohm). The units
are interconnected by wiring all the terminals marked 1
together, and all the terminals marked 2 together, as shown in
Figure 7. An opening should be made in the label covering the
wiring hole in the base, and the wires routed into the unit as
shown. Note that the wiring inside the unit must be kept clear of
the test button contacts, but must not impede the air flow.
Draughts from wiring openings, conduit, or mounting
boxes/holes, may blow smoke away from the sensing chamber,
making it insensitive. It is essential that all such openings are
sealed by silicone sealant or similar.
After wiring together the Interconnect Smoke Alarms, test the
first unit by pressing the button. All the detectors should alarm
within about 5 seconds. Check all the other units similarly.
