ABLE ERMINAL CONNECTIONS
Connected to a screw on the housing exterior.
Power supply (18-32 VDC)
Power supply return (0V)
This output is used for analog 0-20 mA current output
A normally open SPST contact relay, that is energized (closed) when the
detector is in normal operation, and opens in case of fault.
A normally open SPST contact relay, that is open in normal operation,
and closed when fire is detected. This relay can be configured to latch
as described in section (3.4).
Composite (analog) video output
Power supply (18-32 VDC)
Power supply return (0V)
The manual BIT (built-in test) can be initiated by momentarily short
circuiting this terminal and one of the "24 VDC (-)" terminals (2 or 12)".
See 3.8 Manual BIT – Alarm Output Test for more details.
RS-485 Modbus communication (used by the "FGD Communicator"
software)
Ethernet communication, used for digital video (with ONVIF profile S
protocol)
This terminal should be left connected to the housing internal ground
screw.
