Table 48: EOL Resistor Value
The control panel has the ability to be programmed for different values of EOL resistors. This
is a global parameter and will effect all four zones simultaneously. It gives the ability to fit the
Solution 4+4
control panel into an existing installation without having to change the EOL
resistors. This feature also increases the security of the system as there are eleven possible
EOL resistor values that can be used. This makes it extremely difficult for anyone to tamper
with the system.
If split EOL resistors have been selected, the control panel will look for four burglary zones (1-
4) consisting of 3K3 EOL resistors and four 24 hour tamper zones (1–4) consisting of 6K8
resistors connected in parallel. The zone 1 termination on the PCB becomes the termination
for zone 1 and tamper zone 1.
Caution should be exercised when using split EOL resistors to create four burglary
zones and four 24 hour tamper zones. This configuration is only suitable for normally
closed contacts. If normally open contacts are used, as is the case with most types of
smoke detectors, a short circuit on one zone will trigger both zones connected in
parallel.
