Ei Electronics Ei407 Wireless 868.5MHz Interconnectable Red

Lithium 9V, RF, 150m, +5dBM, 868.5 MHz, 85mm x 85mm x 58mm, 191g <b>Product Description</b>
The Ei407 Manual Call Point is an emergency device that when activated transmits a radio frequency (RF) alarm signal. This alarm signal will cause all RadioLINK alarms (in the system) to sound and thereby warn occupants of the immediate danger.

The Ei407 Manual Call Point is powered by tamperproof lithium cells designed to last the life of the product. The cell power is monitored and an end of life signal is given when the batteries are depleted.

The Ei407 Manual Call Point uses advanced radio transceiver technology with unique software coding to transmit the radio signals. The transmissions are frequency modulated (FM) and use Manchester coding to ensure robust signal integrity and avoid signal noise interference

The Ei407 has built in circuitry to aid suppression of voltage transients and RF interference.
