Panel Inputs 1 and 2 Cable 0
The 635/650/750 hub cards are fitted with two multi-function which can be configured either as digital or
analogue input function. The digital inputs are for use when interfacing to volt free contacts. These can
be used for example with slam switches or a relay output from another system such as a fire alarm
panel.
The analogue inputs can be used with 4-20mA loop powered detectors (current sourcing).
The inputs can be configured using the WiFi interface. If using the mA inputs these will need correct
scaling and a one time calibration.
Note that these two inputs are shipped linked with resistors and as digital inputs. This is to prevent
damage should the port be set to mA input. The resistor prevents port damage should the port be
configured to a mA input and the links left in place.
They appear during a FIND command on cable 0 (internal to the hub card) and will have input
addresses 1 and 2 assigned by default. Alarms can be set against these two channels in the same
manner as any other detector. Note these channels are supplied linked out and will always be the first
two channels on the control panel.
