Ei Electronics Ei127 User manual

Pattress Models Ei127 & Ei127R

For use only with Ei140, 141, 144, 145, 146, 161, 161R,

164, 164R, 166, 166R Easi-Fit Smoke/Heat Alarms

The Smoke/Heat Alarm is mounted on the Ei127 & Ei127R.

The Ei127 pattress facilitates installation of bulky wiring and con-

duits.

The Ei127R has an additional socket for connecting to the R

spade terminal on the Ei161R, Ei164R or Ei166R. This can be

used for remote test & hush or manual call points.

WARNING: This pattress must only be used with one of the

above smoke alarms as per these instructions - otherwise the unit

will not comply with the mandatory safety regulations.

Installation

WARNING: First disconnect the mains from the circuit to be used.

1. Choose a mounting position following the siting instructions in

the Smoke/Heat Alarm leaflet. 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 material from the selected knockout, making sure that

there is no gap when mated with ducting / conduit. There are four

knockouts – three on the sidewall and one on the rear.

2. Screw the pattress to the ceiling after first removing the

required knockout and bringing the house wires through it (see

figure 1). Use the longer screws and plasterboard anchors from

the Smoke Alarm pack for this task. If the central knockout is

being used, seal around the wires (and the openings at the rear

of the pattress) with silicone or similar to prevent air draughts

affecting the smoke entering the alarm.

3. Connect the house wires (L - Live, N - Neutral and IC -

Interconnect, if it is being used) to the terminal block on the pat-

tress. If an Ei161R, Ei164R or Ei166R (with remote TEST/HUSH)

is being installed, attach the “R” wire from the Ei152 (see the

Ei152 instructions) to the terminal marked “R” in the pattress (see

figure 1). If the Ei161R, Ei164R or Ei166R is being used with a

manual call point then connect the R terminal to the call point (see

figures 1& 2). Otherwise do not connect anything to the ”R” termi-

nal.

4. Connect the three wires (L, N and IC) from the pattress con-

nector block to the connectors on the Smoke/Heat Alarms mount-

ing plate. Connect the earth wire (if present) from the house wir-

ing directly to the terminal on the mounting plate. Replace the

cover over the terminal wires.

Note: that the house wiring can be connected directly to the

mounting plate if the pattress terminals are not being used for

looping.

5. Screw the mounting plate to the pattress pillars using the two

screws supplied with this kit.

6. Slide the alarm on to the mounting plate.

7. Connect the mains power – the green LED light on the alarm

should be on. When the test button is pressed the horn should

sound.

If an Ei128R or Ei128RBU pattress with relay is being used,

replace the Ei127R with the Ei128R or Ei128RBU and follow the

instructions supplied with it.
