10.2.1 Periodic Testing And Maintenance
To ensure proper and reliable operation, it is recommended that system inspection
and testing be scheduled monthly or as required by national and/or local fire codes.
Testing should be done by a qualified services representative if a malfunction is
encountered.
Before testing:
1) Notify the fire department and/or central alarm receiving station if an alarm
SLC devices are not being recognized
(trouble message "Missing" displays
on the annunciator). Check that SLC loop impedance is within the required range.
To measure impedance, use the following procedure.
1. Disconnect both wires from the terminal block at the panel (SLC
devices can remain connected).
2. Measure the impedance from positive to negative and from nega-
tive to positive. Both measurements should be greater than 500 K
ohms. If the installation uses T-taps, test each T-tap individually.
3. Temporarily connect the positive wire to the negative wire of the
SLC loop at the point farthest from the panel (SLC devices can
remain connected).
4. Measure the impedance from positive to negative and from nega-
tive to positive. Both measurements must be less than 50 ohms.
The panel indicates a ground fault
trouble condition (trouble message
"GROUND FAULT" displays). An earth ground fault occurs when the panel senses an unexpected
flow of current from one or more of its terminals to the earth connection
(Terminal 2).
Isolate the wiring that is causing the fault by removing wiring
connections one at a time until the earth fault is no longer present.
Pause at least five seconds after removing a wire before removing the
next one.
The panel will also go into ground fault if a computer is connected to
the panel via a serial cable attached to the panel’s 9-pin connector.
This is a correct method for on-site communication between a panel
and a computer. Ignore the ground fault message in this case. The
trouble will clear automatically when you disconnect the computer from
the cable
5815XL module that has been
physically connected to the panel but
is not being recognized. Check the status of the 5815XL green LED. If it flashes in the pattern
.5 sec. on / .5 sec. off, it is likely that the 5815XL has not been added
to the system through programming. JumpStart will add any 5815XLs
connected to the panel. If you have already run JumpStart, 5815XLs
can be added manually (see Section 7.3.2).
Check that the correct ID for the 5815XL module has been set through
the DIP switches. Assign ID#1 to the first 5815XL and ID#2 to the
second 5815XL. See Section 4.10.1 for complete details.
If the wiring between the 5815XL and the panel is correct, measure the
voltage from 5815XL Terminal (+) to Terminal (-). Voltage should be in
the range 27.2-27.4V when AC power is present.
If the green LED is not flashing, the likely cause is incorrect wiring from
between the 5815XL and the panel. See Section 4.6.1 for wiring
details.
