Maintenance
Routine inspection: Ensure the module is secure and undamaged.
Operation Test
The purpose of the Operational Test is to confirm the product’s correct
operation.
1)
When carrying out site testing of the product, the control panel
shall be set to “one-man-walk test mode” prior to the test.
2)
Take any necessary precautions to limit the sounding of the alarm
sounders/bells and any fire service summoning device.
3)
Operate a control signal from the control panel to activate NAC
devices, and confirm that the Output LED (red) illuminates.
Note: If the test cannot be carried out as terminal wiring is connected,
remove the wire connected to NAC, and test between terminal S+ and
S-
（
or R+ and R-
）
to check the module. (In the active status, 24V is
output between S+ and S- (or between R+ and R-).
