3. Connect the house wires (L - Live, N - Neutral and IC -
Interconnect, (if it is being used)) to the terminal block on the
Relay Base. If an Ei161R, Ei164R or Ei166R Smoke Alarm is
being used with an Ei152 Control Switch or an
MCP400/MCP401 Manual Call Point, attach the “R” wire from
the Ei152 or the MCP400/MCP401 to the terminal marked “R”
in the Relay Base (see figure 1a & 1b).
If an Ei152 Control Switch and an MCP400/MCP401 Manual
Call Point are being used on the same circuit (see figure 2),
attach both “R” wires to the terminal marked “R” in the Relay
Base. Otherwise do not connect anything to the ”R” terminal.
4. Connect the three wires (“L”, “N” and “IC”) from the Relay
Base to the connectors on the Smoke/Heat Alarms mounting
plate. This “IC” wire must be connected even if it is a single
alarm installation. Connect the earth wire (if present) from the
house wiring directly to the terminal on the mounting plate
(see relevant Smoke Alarm Instructions). Replace the cover
over the terminal wires.
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).
5. Connect the rechargeable cells (Ei128RBU only) by
carefully and gently sliding the switch to the “on” position (see
figure 1b). This switch must be in the ‘on’ position to ensure
correct operation.
6. Screw the mounting plate to the Relay Base pillars using
the two screws supplied.
7. Slide the alarm on to the mounting plate.
8. Re-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.
(Note - with ionisation alarms the relay normally switches 4
seconds after the horn sounds. With optical alarms the relay
normally switches within 2 seconds of the horn sounding).
Note: A maximum of 12 Smoke/Heat Alarm of the types
specified may be interconnected to one Relay Base. When
one alarm senses fire all interconnected units will alarm and
the relay will switch.
3. Checking & Maintaining Your Smoke Alarm System
We recommend a weekly check is made of your alarm system.
When checking the system also check the Relay Base as follows:
