7.4.6.2 Using Diode EOL Devices
The procedure described below is based on the following
assumptions:
a. All sounder circuit cables are in situ with all sounders
b. The sounders are of the electronic type, polarized and
c. Ensure that no jumper link is fitted to JP11.
d. The supplied EOL diode is fitted to each sounder
Note: Before the sounder circuits are connected it is
Procedure:
1 Link out the end-of-line diode. Use a low-voltage

The markings for the Fault Relay connector TB8 on the

Note: The cable resistance must be measured to
check that all sounders receive sufficient
voltage (15V min) for correct operation. The
cable resistance not only determines its
maximum length but also the maximum
number of sounder devices that can be
connected to ensure correct sounder operation.

limit of available power. The panel monitors the sounder
circuits and will report a fault if the impedance of any
sounder cable exceeds 13 Ohms (approx.).
for lower load current - the impedance limit is fixed!
sounders may be tested as described on previous page.
