  • Patent number: 11900788
    Abstract: An electronic control module associated with a fire alarm control panel (FACP) and a wander detection system in communication with security system input detection equipment is disclosed herein. The control module disconnects each of the initiating detection circuits (IDC) in each of the one or more zones of the FACP, preventing manual activation of any of the security system equipment affiliated with the respective IDCs to prevent a wandering patient from otherwise activating and engaging the system. By electronically maintaining at least one leg of the normally open (N.O.) circuit in the open position, in effect utilizing the protective loop of the N.O. circuit in a strategic “open circuit” condition, the module prevents any electronic signal from being sent back to the FACP as is typically the case when a manual pull station is activated.
