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 condition is 
transmitted.

2) Notify facility personnel of a test so that alarm sounding devices are ignored during the test 
period.

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 negative 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 negative 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.
