The Context Plus XP95 Switch Monitor is designed to monitor the state of one or more single pole, volt-free
contacts connected on a single pair of cables and to report the status to Context Plus compatible control equipment.
FEATURESThe Switch Monitor provides four input states to the control equipment: ‘Normal’, ‘Fault’, ‘Pre-alarm’ and ‘Alarm’. The Switch Monitor has a red LED to indicate an alarm and two yellow LEDs to indicate a switch input wiring fault or a loop short-circuit wiring fault. The Switch Monitor is fitted with a bi-directional short-circuit isolator and will be unaffected by a single short-circuit on either loop input or output
