<b>Product Description</b>
The Ei420 is a RadioLINK alarm interface module that is designed to be hard-wired to an Ei260 Series CO alarm to allow it to be integrated into a RadioLINK system. It also has the ability to be used as a standalone RadioLINK repeater module. It is designed to be remotely sited and comes complete with its own cover.
It runs on 230V AC mains power and has built in tamperproof rechargeable Lithium cells that act as a battery backup in the event of mains failure. These rechargeable Lithium cells are designed to have a minimum ten-year life and outlast the life of the module itself.
The Ei420 can be used to interface a hard-wired Ei260 Series CO alarm with a RadioLINK system. The Ei420 has inputs for interconnect wiring and will send out a RadioLINK signal if it receives a hard-wired signal input. Additionally, if the Ei420 receives a RadioLINK signal it will output a hard-wired signal on the interconnect line. This function is designed for use with ‘RC’ Series alarms.
The Ei420 can also be used as a stand-alone RadioLINK repeater module in installations that require additional signal coverage but where the installation of an additional alarm may not be suitable.
The Ei420 uses advanced transceiver and signal coding technology to ensure robust and reliable RF signaling.
<b>Operation</b>
- On receiving a hard-wired signal, the unit will transmit an equivalent RadioLINK signal.
- On receiving a RadioLINK signal, the unit will send out an equivalent hard-wired signal on the interconnect line.
- Received RadioLINK signals will be re-transmitted - increasing the possible number of barriers penetrated by the signal and contributing to multiple signal paths throughout the system.
- The unit can be House-Coded by activating the HouseCode switch. The indicator will flash red to indicate the number of units ‘learned’.
- The indicator will illuminate green to show that mains power is present (this is overridden by any red flashes).
- If the rechargeable back-up is depleted, the indicator will flash red every 10 seconds.
