from the knockout, making sure that there is no gap when
mated with ducting/conduit. There is one suitable knockout
(the other two surface entries are not recommended as the
wiring will reduce the antenna signal). See figure 1b.
4. Screw the Ei428 module to the wall after first removing the
required knockout and bringing the house wires through it
(see figure 1b).
5. Connect the house wires (L-Live, N-Neutral) to the terminal
block as shown in figure 1b (Note the interconnect can be
hard wired to a non radio link Ei mains powered smoke alarm
(Ei141, 144, 146, 151TL, 154TL, 156TLH, 161, 161R, 164,
166, 166R) to switch the relay, if required). NB: The unit must
not be earthed so do not connect a green / yellow or copper
earth wire to any terminal.
6. Connect the wires to the required relay contacts for con-
trolling the auxiliary device. (The contacts are isolated and are
rated at 250VAC, 5 amps resistive).
