Features
 

The base unit has built in circuitry to aid suppression of voltage transients and radio interference.

The system has built in circuitry to aid suppression of voltage transients and radio interference to reduce the chances of false alarms.

The RadioLINK Base transmits a radio frequency alarm signal when the unit attached to it senses fire. When it receives a radio signal from another RadioLINK Base, the attached alarm will sound. It therefore eliminates the need to install long interconnect wires between all the alarms on different floors or in different rooms.

The base unit itself is also mains powered and has rechargeable lithium battery for back-up in the event of mains failure (SKU TL SD168).

The base will normally be wired to the nearest mains circuit in the ceiling (usually the lighting circuit). The alarm is then slid onto the base - as twelve units can be interconnected in this way

The radio range can be extensively improved by either adjusting the wire antenna or by converting the base into a repeater - which then extends the range.

The alarm is triggered when the optimum temperature is reached. This is ideal for use in kitchens and garages, where the use of optical or ionisation alarms could lead to potential false alarms.  

Advanced features include the ability to interconnect up to twelve alarms to allow all alarms to sound if just one of the interconnected alarms should be triggered.

Mains RadioLINK Heat Alarm (Alkaline battery backup)

This is a Heat Alarm that runs on 230V AC mains power, and has a 9V alkaline battery back up in the event of mains failure. The 9V battery will last for up to 4 years in standby mode, and capable of powering the smoke detector for up to 2 years in the event of mains failure.
