This is the Aico EI603RF 10 Year Lithium Battery powered heat alarm suitable for kitches and areas where smoke alarms may be subjected to false alarms.

Please note: this item is non-returnable; due to the nature of this item, it has an electronic component and sensor, and we cannot take this item back for a refund as "unwanted".

It comes RadioLINK enabled so that one alarm would sound all alarms in the system. It has an aesthetically pleasing design, very compact, and the battery capacity is sufficient to outlast the useful lifespan of the alarm. The Test button is large right in the middle, easy to use, and the base is easy to fit - "twist-on" base. 

Aico Ei603RF Battery Heat Alarm - Features and Benefits

  • This alarm is activated by heat from fire, not smoke; it makes it ideal for kitchen installations where smoke detectors are prone to nuisance alarms.
  • The Aico Ei603RF is interconnected to other smoke / heat Alarms in the dwelling or escape routes to ensure that all occupants are alerted to the danger.
  • Battery powered alarm: 10-year Lithium battery included, non-replaceable.
  • Aico Ei603RF heat Alarms and other RadioLINK smoke Alarms must be house coded. This will avoid interference and interconnection with other RadioLINK systems. You can link up to 12 battery powered smoke and heat alarms using either hardwire or RF connection. The RadioLINK enabled smoke and / or heat alarms can be house coded as a system to prevent communication with other nearby RadioLINK systems.
  • The twist-on base powers the alarm; when alarm is not powered, the battery power is not consumed (when stored, etc). 

Please note that the 10-year guarantee period is from the year of the manufacture and not from the year of purchase. Therefore, if the alarm is purchased 5 years after the manufacture (for example), the guarantee is only for 5 years.
