Alert Units are separate boards that contain 2 wet relay outputs that can be used to attach a "strobe" or a horn "siren" to trigger in the event of an alarm condition.
This article will describe how to add an Alert Unit to the Security Escort software.
In the context of Bosch AMS (Access Management System), a "man-trap" refers to a security feature used to control access to a restricted area. This setup helps prevent unauthorized individuals from entering a secure area by trapping them between the doors until their identity and authorization can be verified.
This guide would be useful if a relay needs to be triggered from an access event to a external system.
Ex: to sound a siren, turn on an LED, trigger another external relay, etc.
