Detcon FL-10 - Manual (Page 3)

2.0 D ESCRIPTION
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 haz-
ardous or explosion proof (NEMA 7).
Any combination of Model FL10 Flame detector control modules and Detcon gas sensor Model 10 control modules may be
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 func-
tions are alarm 1 and alarm 2, and fault (alarms 1 and 2 share the same alarm LED indicator). All alarms are switch program-
mable 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.

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 pro-
grammed latching. It also acts as an alarm relay test function.
