Walk Test Operation
A walk test allows an installer to verify the Initiating Circuit wiring in a system. To enter walk test, press and hold both the Buzzer
Silence and Lamp Test momentary switches for at least one second. You can identify circuits to be tested using the Circuit
Disconnect slide switches. Confi guration SW9 #3 Zone Disconnect Enable/Disable must be set to “ON” to allow Walk Test
Operation. Activation of any initiating circuit that has been selected for the walk test will cause the audible NAC circuits to
activate briefl y for a number of short bursts corresponding to the circuit number. Any subsequent activations on the same initiating
circuit will activate the audible NAC circuit only once. If another initiating circuit is activated then the audible NAC circuits will
activate for a number of short bursts corresponding to the circuit number of the new zone being walk-tested, and so on.
For example, if Initiating Circuit #3 is fi rst activated, the indication circuits will sound for three bursts. Any subsequent
activations of Initiating Circuit #3 will sound for one burst. The initial burst interval denoting the count of the circuit number is
one second on followed by 1/2 second off. The subsequent burst interval denoting additional activations on the same initiating
circuit is 1/2 second on then off. After the sounding pattern has been sent on the NAC circuits, the initiating circuit is reset and
tested again. If it is still active (in alarm) the pattern will be re-sent. Trouble on any initiating circuit when in walk test mode
causes all NAC circuits to be activated continuously for fi ve seconds.
Alarm verifi cation and water-fl ow alarm retard operations are disabled on circuits being walk tested. All circuits not selected for
walk-test continue to function normally. The walk test operation is disabled if the fi re alarm control panel is in alarm or goes into
alarm while walk-test is active. It will also time out after 60 minutes of no activity.
