This system creates an invisible alarm barrier with a 20mtr (75ft) range between the two units -
3 mode sounder - chime, chime/c continuous and alarm sound!

Extremely simple to set up: switch on the transmitter, line up the receiver to face the transmitter(up to 20mtr away) and switch both on. The receiver will sound whenever the invisible infra-red beam is broken. It can be set to chime once or chime continuously (with volume adjustable to low, medium or high) or set to a continuous high level alarm. Each pair features a coded infrared transmission and a switch for high or low power output. Both of the units require three AA batteries or a 6V plug-in mains adaptor each (not included). This is not a portable alarm system, it is meant for a door way or room controlled entry
