Table 77: EOL Resistor Value
The control panel has the ability to be programmed for different values of EOL (End Of Line)
resistors. This is a global parameter and will effect all four zones simultaneously. It gives the ability
to fit the
Solution Ultima 844/862/880 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 zones (5–8) consisting of 6K8 resistors connected in
parallel. The zone 1 terminal on the PCB becomes the terminal for zones 1 and 5.
Caution should be exercised when using split EOL resistors to create eight burglary zones and
four 24-hour zones. This configuration is normally only suitable for N/C contacts. If N/O
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.
If you require N/O contacts when using split EOL resistors, refer to Connections Of Split EOL
Resistors Using N/O Contacts on page 168 for more information.
