Abstract

Example aspects include techniques for managing alarm initiating devices. These techniques may include receiving, at a control panel, a first signal indicating that an alarm initiating device has entered a test mode in response to activation of a test switch of the alarm initiating device. In addition, the techniques may include updating, at the control panel, device information to indicate that the alarm initiating device has entered a test mode and receiving, at the control panel, a second signal indicating detection of a hazard indication at the alarm initiating device. Further, the techniques may include preventing an alarm alert process of the control panel associated with the hazard indication based upon on the device information indicating that the alarm initiating device has entered the test mode.
