Abstract
According to systems and methods for testing alarm initiating devices of a fire alarm system, a control panel of the fire alarm system is placed into test mode. Then, during a walkthrough test, an inspector activates an inspector-activated mechanism of a device. This sends a test mode signal to the control panel, which places the device into a test mode. The inspector or inspector then manually activates the device. The control panel initiates a fire alarm condition in response to a received device signals while the control panel not initiating a fire alarm condition when the device signals are indicative of a fire if the device signals were from alarm initiating devices in the test mode. Alternatively, the control panel places a group of alarm initiating devices into test mode on a rolling basis. As the inspector tests the devices, additional devices are added to the group and previously tested devices are returned to normal operation mode.
