3. Installation
The wiring resistance of the cable to the detector (including joints) should be
restricted to a maximum of 100 ohms. The recommended maximum cable
distance per zone is 200 - 300 metres.

EOL Connections
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
short circuit "Tamper" signals. Figure 13 shows how to connect two EOL
detectors to adjacent zones. Note that each detector is wired in series to a
common anti tamper circuit connected to terminals marked "3". You must
connect a single 2K2 resistor in series with the anti tamper circuit.
