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.
