Product Description  
Operation  
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 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 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 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 Ei173 control panel also incorporates a Test button  
and circuitry to continuously monitor the system wiring  
The “Test” button will check the strobe, vibration pad  
and panel  
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  
When the Ei105CD optical smoke alarm is activated,  
the Ei173 control panel will flash the strobe at 1Hz and  
activate the vibrating pad  
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.  
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
