Such a small unit to guard such a wide opening!!
The unobtrusive INFRA RED watchdog that is simplest to install, doesn't rely on batteries and gives an added feeling of security knowing it can't be fooled by reflectors...and with the buzzer able to be installed some distance away, any unwanted intruder may be unaware of being announced!
The system is set to give one short buzz and lock out for approximately three seconds before re-setting itself. The lens lights up during this time. The power pack & timer senses when the circuit opens and operates the buzzer, resetting after the circuit closes. This means the buzzer does not sound continuously if a person or persons remain stationary in the beam.
