brown: live
blue:
neutral
The wire which is coloured blue must be connected to the
terminal/wire which is marked with the letter N or coloured
black.
The wire which is coloured brown must be connected to the
terminal/wire which is marked with the letter L or coloured red.
The apparatus is not to be earthed, so no connection is to be
made to terminals or wires marked with the letter E, the sym-
bol
or coloured green or green and yellow.
Bring the low voltage wiring from the control panel to where
the smoke alarm is to be located. Route all wires neatly and
securely along the walls and ceilings.
Note: Turning off the power switch on the Control Panel
does not switch off the apparatus from the supply mains. The
switch removes the AC and battery power from the Control
Panel, but the mains transformer remains connected to the
supply mains.
Vibration Pad
Plug the vibration pad into its locking socket on the control
panel. Place the vibration pad under the pillow or mattress. It
is important that the person in the bed can feel the vibration -
check it is sufficient to wake a person by lying on the bed and
pressing the test button on the control panel - see also “Test-
ing your system”. Some mattresses may not transmit suffi-
cient vibration, and in these cases it should be fitted under the
pillow. Note: During testing, or in an actual alarm situation,
the pad pulses on and off for greater effect on sleepers.
Mains Smoke Alarm Interface Pattress Ei 172/160
The pattress is used to mount the smoke alarm in its location,
to connect it to the mains and interconnect wires, and to con-
nect it to the wires from the Ei 173 control panel.
(The connec-
tions from the non-isolated mains powered smoke alarms, to the low
voltage control panel wires are through an opto-isolator in the Ei
172/160 for electrical safety).
1. Choose the mounting position following the siting instruc-
tions in the Smoke Alarm leaflet. Remove the power from the
circuit you plan to use.
2. Where the incoming mains and interconnect wires are on
the surface of the ceiling or wall the appropriately sized duct-
ing/conduit must be chosen to mate with the unit.
3. The low voltage wiring from the control panel must not be
run in the same conduit as the mains/interconnect wires.
4. Using a sharp knife remove material from the appropriate
knockouts making sure that there is no gap, either where
mated with the ducting/conduit or with the low voltage wires.
There are three knockouts and one on the rear.
5. Screw the pattress to the surface using the two screws
and plastic plugs supplied.
6. Figure 1 shows the connections. Connect the incoming
live, neutral, and interconnect (from other smoke alarms if
present) to the pre-wired connector block. The Pattress does
not require an Earth. The three wires for connecting to the
smoke alarm mounting plate are already wired to the pattress.
Connect the red wire (remove the small piece of insulating
tape first) from the control panel to the terminal marked “R”
and the yellow wire to the terminal marked “Y”. The black and
blue wires from the control panel are not used. They should
both be connected to the spare terminal for extra strain relief.
7. Bring the mounting plate wires out through the hole in the
mounting plate as shown in figure 2. Connect the three wires
to the mounting plate terminals following the wiring colours
specified in figure 2. Note: The white interconnect wire must
be connected to the smoke alarm (even if there is only one
smoke alarm on the system).
8. Replace the wiring cover on the mounting plate. Slide the
Smoke Alarm on to the mountig plate.
Interconnecting Smoke Alarms
A maximum of 12 Ei 140,141,144,145,146,161,164,166
Smoke/Heat Alarms may be interconnected to one Ei 172/160
unit. When one alarm senses fire all interconnected units will
sound and the control panel will turn on the strobe light and vi-
bration pad (See Smoke/Heat Alarm instruction leaflet for fur-
ther details on
interconnection wiring).
Warning : Do not connect to any other type of Smoke/Heat
Alarm. Doing this may damage the alarms and could result in a
shock or fire damage.
N o t e 1 : A n a l a r m w i t h b a t t e r y b a c k - u p ( i . e . E i
141,144,146,161,164,166) will continue to operate during
mains failure and will be able to signal the control panel if they
sense fire.
The control panel also has battery back-up, so that it too will
operate during mains failure.
