Wiring a Door Sensing Device / AutoCall Wiring a Door Sensing Device The units can monitor the position of up to four doors/gates and may react to a change in their status with one of the relays (not set as a control relay). For example, if a door is pried open or is held open after its relay deactivates, the unit will record the breach in its transactions and can perform the following actions: • Energize a relay to activate an alarm device such as a siren, light or CCTV camera. • Main use is to terminate strike time early.

NOTE: Door sensing device should provide contact closure when door is closed. Wiring the AutoCall Feature Using the AutoCall feature, the unit will automatically call the main residence phone when a driveway sensor is activated (any device that provides a contact closure). For example, when a visitor drives over a loop sensor that is connected to the AutoCall feature, the unit will call the main residence phone automatically so the visitor can speak to the resident without pressing the call button on the unit.
