EOL Connections (9851 only)

Each EOL zone is a two-wire closed loop that uses a single 2K2 resistor fitted

in series with the alarm contacts to differentiate between "Circuit" and

"Tamper" signals. Figure 22 shows how to connect two EOL detectors to

adjacent zones. Each detector is wired in series with a common anti-tamper

circuit, which is connected to the terminals marked "3" and "4". You must

connect a single 2K2 resistor in series with the anti-tamper circuit.

Figure 23. Connecting a 9954 Expander

When fitting a 9954 hardwired expander, make sure that you place the jumper

link on the expander in the correct position to select either four-wire CCL, or

two-wire FSL or EOL.
