Smoke Alarm Locator
Model EI 159
The Locator is recommended for all installations having three
or more smoke alarms interconnected. The Smoke Alarm Loca
tor stops all the units alarming except those smoke alarms actu
ally sensing smoke, by disabling the interconnect feature for
about 10 minutes. Thesource of the alarm can quicklybelocated
and appropriate action taken (e.g. evacuate the premises, clear
cooking fumes etc). It significantly reduces the annoyance to
other occupants while an alarm is being investigated, this is par
ticularly useful when an alarm occurs at night. (Disconnecting
the AC mains will not silence smoke alarms with battery backup). The Locator switch automatically restores the interconnect
feature after about 10 minutes. (If the original Smoke Alarm con
tinues to soundafter smoke has cleared, pressthe locator button
again to cancel)
It is easily installed as shown in the circuit diagrams. It must
not be used with smoke alarms from any other manufacturer.
Near the distributionboard is often a goodpositionfor the Smoke
Alarm Locator. Mains poweredsystemsmust be wired according
to IEE regulations. The interconnect wire (terminal 1) and the
neutral wire (terminal 2) are connected to the two terminals on
the loose terminal block. (Note no connections are to be made to
the other terminals on this switch). Pushing the switch starts the
timer circuit and holds the interconnect line close to zero volts
and so none of the smoke alarms can signal to each other. However each individual smoke alarm will still operate and alarm if it
senses smoke itself. Ensure wiring in switch housing is double
insulated from the face plate screws.
