Ei Electronics Carbon Monoxide Alarm Ei 205ENA - Manual (Page 18)

1. Slide off the battery cover as shown in
Figure 5a.
2. On the first unit connect twin core
cable to the terminals marked 1 and 2 as
shown in Figure 8 and bring the cable out
through the hole above the terminal
block.
3. If they are being surface wired, break
one of the three knockouts on the rear
side wall. (We do not recommend
bringing the wires out the top as cable
conduit can prevent the battery box
opening).
4. Screw the unit to the wall using the mounting holes.
5. Wire all the rest of the alarms similarly ensuring the terminals marked 1 are all
connected together and that the terminals marked 2 are all connected together.
6. After installation press each test button (for at least 15 seconds) in turn and ensure
each interconnected unit sounds within 10 seconds. The light (either green or red) will
only flash rapidly on the unit with the test button pressed.
These Carbon Monoxide Alarms should only be interconnected within the confines of a
single family living unit. If they are connected between different units there may be
excessive nuisance alarms - everybody may not be aware when they are being tested.
