End Of Line Circuitry
The following describes the EOL tamper alarms circuitry needed when EOL has been configured. There
should be two resistive values within the tamper alarm circuitry. These must be located inside the alarm
device (furthest point from the unit).
The alarm state could be Normally Open or Normally closed however the tamper states are the same for
both settings.
Open, the resistive value is 6.8K ohms (1K + 5.6K).
Closed, the resistive value is 1K ohms, as the circuit does not see the 5.6K ohm resistor.
Open Circuit Tamper, the resistive value is infinity as the circuit has been cut and
therefore is 'open'.
Short Circuit Tamper, the resistive value is 0 Ohms.
