Product Description
The Ei405 is an Optical Smoke Alarm that runs on 9V alkaline battery and is part of the RadioLINK range of RF alarms. The RF signal will wirelessly interconnect the Ei405 to other RadioLINK products
The Ei405 uses advanced radio transciever technology with unique software coding to transmit and receive the radio signals. The transmissions are frequency modulated (FM) and use Manchester coding to ensure robust signal integrity and avoid signal noise interference
The RF range can be extensively improved by converting the alarm into a “repeater” i.e. re-transmission of the RF signals. The Ei405 series alarms can be used as a stand alone wireless interconnect system or be incorporated into existing home security systems
The Ei405 has other advanced features such as high performance optical chambers fitted with integral insect screens to reduce the chances of false alarms, as well as the ability to wireless interconnect up to twelve alarms to allow all alarms to sound if just one of the interconnected alarms should be triggered.
The Ei405 has built in circuitry to aid suppression of voltage transients and RF interference to further reduce the chances of false alarms under such conditions
Applications
The new Ei 405 series of RF Smoke Alarms using 9Volt Alkaline battery is designed to facilitate easy installation and to provide maintenance free operation. Proven and trusted Ei Smoke Alarm technology is incorporated in a new profile alarm that is quick and easy to install and interconnects without wiring.
The 405 series RF Smoke Alarms can be used as a stand alone wireless interconnected system or be incorporated into existing Home Security Systems to provide Fire as well as Security Safety
