The Ei407 is a manual call point used in case of emergency to sound all the Alarms in a RF system, warning all the occupants of the immediate danger.

It is powered by a 10 year lithium battery.

When the front plate is pressed, a yellow band appears at the top of the plate to indicate that the Ei407 has been activated and the LED will flash red. It will remain that way until it is reset. Using the resetting key, the plate can be pushed back to its original position which will cause the yellow indicator to disappear, the LED to stop flashing red and the Alarms to stop sounding.

The Ei407 uses advanced radio transceiver technology with unique software coding to transmit the proprietary RadioLINK protocol. This ensures a robust “mesh” of RF signals and reliable paths of communication. The house coding feature confines the RF communication to designated devices only, thereby avoiding the inadvertent activation of neighbouring alarm RF systems.

A RF system consists of Ei Electronics Smoke, Heat, CO Alarms and accessory devices that are linked using a proprietary RF protocol. The Ei407 must be House coded to the other RF devices in the system.

It is supplied with the necessary fixings for a quick and simple installation and a resetting key.
