Product Description
The Ei176 is a complete smoke alarm system designed
for the deaf and hard of hearing. The system includes
the Ei173 control panel, Ei174 vibrating pad and
Ei105CD optical smoke alarm.
The Ei173 control panel includes a high intensity Xenon
strobe, a sealed lead-acid rechargeable battery for
standby use in the event of mains failure and all the
required circuitry to connect to the Ei105CD smoke
alarm and Ei174 vibrating pad
The Ei173 control panel also incorporates a Test button
and circuitry to continuously monitor the system wiring
The Ei174 vibrating pad is designed to be placed under
the mattress or pillow to waken people who fail to
respond to the strobe alarm
Up to 11 other smoke/heat alarms (Ei100C/105C/103C)
can be interconnected to the master smoke alarm
Ei100CD. The smoke alarms are all powered from the
control panel and in the event of mains failure the
rechargeable battery in the panel will power the entire
system, including the smoke alarms, for one week.
Operation
The green indicator will illuminate to show mains power
is present
The red indicator will flash once every second to show
that the mains supply is off and the system is running
on battery backup power
The red indicator will go off as the battery becomes
depleted (with mains off)
The slide switch on the control panel disconnects mains
and battery power from the control panel and
extinguishes both LED indicators
The “Test” button will check the strobe, vibration pad
and panel
When the Ei105CD optical smoke alarm is activated,
the Ei173 control panel will flash the strobe at 1Hz and
activate the vibrating pad
The interconnect wiring from the smoke alarm to the
control panel is monitored so that if the smoke alarm is
not connected or if it is open/short circuit, then the
strobe will flash and the vibrating pad will turn on
An auxiliary socket allows the connection of an extra
strobe or vibrating pad
MAINS POWERED 230V~

Placement Information
Alarms should be placed in accordance with the general guidelines shown in
the diagram above. These recommendations are based on the problem of
areas of “dead air” close to corners of rooms and apexes of ceilings, which
could result in the prevention of smoke reaching the smoke detector
Important Precaution:
Do not install the actual smoke/heat
alarm itself in new or renovated
buildings until all work is completed
(including floor coverings) and the
building has been fully cleaned.
The wiring can be installed when
appropriate. (Excessive dust and
debris from building work can
contaminate the smoke chamber
and cause problems, and it will also
invalidate the guarantee). If it must
be installed, cover it completely,
particularly around the edges, with
a dust cover (eg. a plastic bag),
until all cleaning is finished..
Connect wires to the unit as in
wiring diagram. All wiring must
comply with local codes.
