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) Turn on the external input connected to the module, and the module
will be in an active condition. Confirm that an active signal is
transmitted to the control panel.
Note: If the test cannot be carried out through the external input,
remove the wire connected to the external input, and test the area
between A+ and A- to check the module. (In accordance with subtype
setting, set the status either 0Ω short (for subtype 1-2), 2.2kΩ short
(for subtype 5-6), or open (for subtype 3-4).)
4) After the external input has brought the module into the active
condition, reset the external input. Confirm that the module goes
back to the initial status after the external input is reset on the
control panel.
5) If subtype is set as 1 and 2, or 5 and 6, open between terminal A+
and A-, and confirm that the control panel detects the open circuit.
If subtype is set as 3-6, short between terminal A+ and A-, and
confirm that the control panel detects the short circuit.
