3.7 Modbus Address
The detector can communicate with the “communicator” software using a Modbus RTU compatible
protocol on RS-485. This protocol allows for a network of detectors to be connected, each with a
unique Modbus address. The address of the detector can be set to any value in the range 1–247.
3.8 Manual BIT – Alarm Output Test
When enabled, the alarm outputs are activated when a Manual BIT is initiated. See section 5.2 –
“Testing” for details.
WARNING
Make sure to disable all fire extinguishing actions or alarms connected to the detector when the
manual BIT is initiated and the “Manual BIT – Alarm Output Test” is enabled as the Manual BIT will
set the 0-20mA terminal to 20mA and close the alarm relay.
