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 inputs connected to the module, and confirm
that the module is in active condition and the input LED (red)
illuminates. Confirm that an active signal is transmitted to the
control panel.
Note: If the test cannot be carried out through the external inputs, test the
area between terminal A+ and A-
（
or B+ and B-
）
to check the module. (In
accordance with the subtype setting, set the status either 0
Ω
short (for
subtype 1-4), 2.2k
Ω
short (for subtype 7-9), or open (for subtype 5-6).)
4)
After the external inputs have brought the module into the active
condition, reset the external inputs. Confirm that the module goes
back to the initial status after the external inputs are reset.
5)
If subtype is set as 1-4, or 7-10, open between terminal A+ and A-
（
or
B+ and B-
）
and confirm that the control panel detects the open
circuit. If subtype is set as 5-10, short between terminal A+ and A-
（
or
B+ and B-
）
and confirm that the control panel detects the short
circuit.
6)
Short between terminal Lin+ (Lout+) and Lin- (Lout-), and the SCI
LED (yellow) illuminates. The short circuit isolator isolates the
devices connected after the short-circuited area, which makes these
devices have no response. Upon removal of the short condition, the
area is automatically connected to go back to the normal standby
status, and the SCI LED (yellow) turns off.
