Caravan Alarm System Controlled by LPRS Wireless Keyfob and Receiver Module

Manufactured in the UK by Keen Electronics the PROTECTOR TWO caravan alarm and light controller is an updated version of the original PROTECTOR alarm now fitted to thousands of Lunar Caravans. The LPRS keyfob offers users the ability to turn the alarm system on and off and also an external awning light for additional security. The keyfob also features a panic alarm function in response to requests from caravan owners who travel abroad.

The alarm system is very simple to use as the keyfob buttons are clearly marked for their specific functions; ALARM and LIGHT, removing the need for ambiguous pictograms. Simplicity of use is a key feature of both Keen Electronics and LPRS products.

The keyfob has a plastic case and buttons, measures just 50x38x13mm and has LED light signalling when operated.
