« BX-OI3 »


BX-OI3

Contains a relay output with a programmable fail-safe position, two inputs for monitored querying of potential-free contacts and an optocoupler input for monitoring external voltages. In addition, the voltage on the loop circuit is internally monitored for low voltage. The BX-OI3 is particularly well-suited for connecting special detectors (flame and line detectors, smoke aspirating systems etc.). Both the addressing of the module and the setting of parameters for connected special detectors (e.g. how they behave when there is an alarm or a fault) is carried out via the fire alarm control panel using PC software. An IP 66 protection class plastic case is used for fitting the module, which can be fitted with various different cable in lets as required. Shipped including 4 180 Ohm resistors for the monitored inputs.
