Pulse counter card for the connection of 2 independent inertial sensors for monitoring window panes, doors or walls. Equipped with a trimmer for individual adjustment of the sensitivity threshold of each sensor connected. Designed to detect very fast pulses (inertial sensors), it is also suitable for pulses with a duration of 3 to 30ms. Complete with a LED for visually indicating reception of the pulse from the connected sensors, and with a relay with free contact for relaying the pulse to the control panel, thereby alarming the control panel concerned.
