Description Full Description

Ei603CRF RadioLINK Battery Heat Alarm is powered by a 9V Alkaline battery and is activated by heat from a fire, not smoke. This makes it ideal for kitchen installations where smoke alarms are prone to nuisance alarms. The thermistor will trigger the alarm when the activation temperature of 58ºC is reached.

RadioLINK wireless interconnection technology is built in to link this alarm in with the rest of the system. This will automatically activate once the alarm is powered up.

As this alarm contains a 9V Alkaline battery, we recommend you replace the battery every 12 months to ensure contained protection. We also have an RadioLINK+ Battery Heat Alarm with a 10 year life, sealed in lithium cell providing the same level of protection, but without the need to replace the battery.
