1. Install the Carbon Monoxide / Smoke / Heat Alarm as
described in the leaflet supplied with the unit. The Relay
Module can be located near the fuse box or in some other
location convenient to the Carbon Monoxide / Smoke / Heat
Alarm wiring. Where the incoming wiring is on the surface of
the ceiling, the appropriately sized ducting/conduit must be
chosen to mate with the unit. Use a sharp knife to remove to
material from the selected knockout, making sure that there is
no gap when mated with ducting / conduit. There are three
knockouts – two on the sidewall and one on the rear.
2. Screw the Relay Base to the ceiling after first removing the
required knockout and bringing the house wires through it
(see figures 1a & 1b).
3. Connect the three wires (L - Live, N - Neutral and IC -
Interconnect) from the Carbon Monoxide / Smoke / Heat
Alarm to the alarm relay module as shown in figures 1a & 1b.
The IC - Interconnect wire must be connected even if it is a
single alarm installation.
As an Easi-fit Alarm is not being mounted on top of the Relay
Base, remove the three cables (for the Easi-fit Alarm connection)
from the terminal block and discard (see figures 1a & 1b).
Connect the wires to the required relay contacts for controlling
the auxiliary device (the contacts are isolated and are rated at
250VAC, 5 Amps resistive). If momentary (pulse) relay
operation is required, carefully and gently slide the yellow
switch to the ‘off’ (Ei128R) or ‘P’ (Ei128RBU) position with a
small screwdriver (see figures 1a & 1b).
4. Screw the cover plate to the Relay Module using the two
screws supplied.
5. Connect the mains power – the green LED light on the
alarm should be on. When the test button is pressed the horn
should sound and the relay will switch within 10 seconds.
With some alarms it may take up to 5 seconds for the relay to
switch after the horn has sounded.
Note 1: A maximum of 12 Carbon Monoxide Alarms or 12
Smoke Alarm of the types specified may be interconnected to
one Relay Base. When one unit alarms all interconnected
units will alarm and the relay will switch.
