● Monitoring the input line for open line and short-circuit with terminating resistors
● The input for status or alarm messages can be configured using the fire control
panel.
● Output which can be configured via jumper:
– Not monitorable: Potential-free relay contact (AC 22 V, 2 A or DC 30 V,
2 A)
– Monitorable: Relay contact (DC 30 V, 2 A)
● Status indicator by means of LED
● Fields of application:
– To activate a potential-free normally open or normally closed contact in
order to report technical statuses (e.g., fan control) or to activate an alarm
(e.g., sprinkler alarm)
– For decentralized activation of alarming devices, fans, air conditioning
systems, lift controls, etc.
