The Ei660i Alarm is a Multi-Sensor Alarm containing 2 separate sensing elements, intelligently monitored, in order to detect the presence of fire. In addition, the chamber design, integrated insect screen and unique dust compensation algorithm reduce the risk of false alarms.

The Ei660i has a sealed built in 10 Year Lithium battery giving you peace of mind as no battery replacement is required. The Ei660i can operate as a standalone Alarm or can be interconnected
wirelessly using the Ei600MRF RadioLINK+ module (sold separately) enabling it to communicate with compatible Ei Alarms and accessories. Up to 12 devices can be interconnected. Alarms interconnected wirelessly must be house coded as a system to prevent communication with other nearby RF systems.

The AudioLINK feature facilitates acoustic download of the Alarm parameters and status using the Ei Electronics AudioLINK app. For better hearing comfort, the sound level of the alarm increases progressively in Test mode. The Test button can also be used to silence nuisance alarms for a 10 minute period and fault beeps for 12 hours (low battery and sensor fault).

The Ei660i self-checks its sensor, battery voltage and internal circuitry every 40 seconds. Any fault condition found will be indicated by a combination of Yellow LED flashes and sound beeps.

The Alarm has a twist on mounting base which has multiple fixing points so it can be easily installed. The Alarm is not powered until it is twisted onto the mounting base, thus avoiding battery power consumption during storage and prior to installation.
