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.
