An interface device includes an elongated sensor strap having a secured end and an unsecured end opposite to the secured end. The unsecured end of the sensor strap represents a first sensor half, and a second sensor half is adapted to receive the first sensor half/unsecured end to form a sensor link between the two sensor halves. A deployment sensor switch provides an input to a monitoring device for an alarm system. The deployment sensor switch is adapted to reside in an armed state when the first and second sensor halves form a sensor link, but change to an alarm state when the first sensor half and second sensor half are separated to break the sensor link. The sensor strap is sufficiently long to produce a closed loop around a firearm or other object to in a monitored position when the first and second sensor halves are placed together to form the sensor link.
