2.0 DESCRIPTION

Alarm set points — Alarm 1 and Alarm 2 are preset to activate
when the input signal exceeds 18 mA. Both Alarm 1 and
Alarm 2 share the same alarm front panel LED indicator.

The fault alarm, depending on the switch programmable
configuration, will activate on loss of power, internal power
supply fault, or 0 mA fault signal from flame detector.

The alarm reset switch resets alarms that have been pro­grammed latching. It also acts as an alarm relay test function.

Power - LED indicator

Detcon Model FL10 single Flame detector digital control modules are designed to supervise and display the status of a
single remote Flame detector assembly with 4-20 mA input. Model FL10 Series control modules are designed to operate
on an input voltage of 24 VDC and are compatible with a complete line of Detcon enclosures and mainframe hardware
assemblies. The available enclosures include designs for rack or panel mounting in non-hazardous areas (NEMA 1), for
weather proof outdoor location in non-hazardous areas (NEMA 4), and for location in areas electrically classified haz­ardous or explosion proof (NEMA 7).

Any combination of Model FL10
installed in a common mainframe assembly thereby providing monitoring for fire and gases. Model FL10 control modules
are compatible with a linear 4-20 mA DC input signal. The module features RS-485 Modbus™ serial output, 4-20 mA analog
signal output, and 3 alarm relays that are status displayed via light emitting diodes located on the front panel. Alarm func­tions are alarm 1 and alarm 2, and fault (alarms 1 and 2 share the same alarm LED indicator). All alarms are switch program­mable for latching or non-latching operation with a common front panel reset switch. The reset is part of a common bus
when installed in a mainframe, allowing for the use of an external reset switch common to all modules in the mainframe.
