2.4.11 GPIO-Interface
The GPIO interface (HD-SUB 25, female) provides for the connection of alarm detectors. For this use
the GPIO connector set which can be obtained as an accessory from your system integrator or
DResearch. Up to 6 sensors (digital inputs, optocoupler inputs) and 4 digital switch outputs (relays)
can be connected.
