CM900 is a small device; it has 2 completely separable and partitionable configurable inputs: an internal REED and a clamped input for an external generic contact.

It communicates with the control panel by a bidirectional digital radio transmission channel to avoid signal collisions or band saturation and ensure high stability and precision. The 128 bit AES encryption code guarantee an high security.

It’s provided with anti-opening protection. It’s also supervised (automatic life test). The standard lithium-ions battery allows a very long duration.

Dimensions:  37 (W) x 78 (H) x 21 mm (D).
