4015B/M Sensor Bus

Magnetic micro contact with 2 expansions inputs (NC / Pulse Count)

This device was built to protect fxtures against opening: It features a magnet that detects a breach when it is moved away from the body of the contact. Sensor Bus is also ftted with a 2-input terminal board which allows:
- one or more contacts to be connected to each other in series;
- a wire detector for window blinds operating with NC/NO switching counts to be connected.

The product is fxed at the fxture jamb, positioning the magnet on the mobile part of the fxture, so that the alarm is set off when it moves away from the main body of the sensor. The three types of alarm are managed individually by the control panel.

It signals the opening of the door + 2 inputs for other passive sensors. Specifc use in the protection of fxtures, both their indoor and outdoor perimeter.
