Detcon Model 610A-FB control enclosure is a NEMA 4X molded fiberglass case with hinged, gasketed door
and is designed for surface mounting in both indoor and outdoor locations. An unbreakable glass view window is gasket mounted in the door. The NEMA 4X rating is by definition raintight and therefore suitable
for outdoor location in electrically non-hazardous environments.
The control enclosure houses the mainframe hardware compatible with Detcon Model Series 10A digital
electronic controls. Model 610A-FB system capacity is up to 6 channels consisting of remote mounted area
sensors and single channel electronic controls (Detcon Model 10A). The system is powered by AC line
power and/or 24 VDC unless otherwise specified at time of order.
The control enclosure includes, as standard operating controls (see figure 1); a power on/off switch, an
alarm disable switch and a line power fuse. Discreet output terminal strips located on the controller mother
board are provided for sensor terminations, Form C dry contact alarm outputs, 4-20ma outputs for remote

recording devices, AC power in, DC power in, remote reset as well as relay logic and power terminations for
the multiple alarm relay circuit. Form C relay outputs may be discreet, zoned or common by gold plated
jumper tabs located on the controller mother board. Form C dry contacts; common, normally open and normally closed, are provided for 3 alarms; High, Low and Fault. Contacts are rated at .6 amp @125 VAC / 2
amp @ 30 VDC. When used in conjunction with the multiple alarm relay circuit (part #5026), contacts are
rated 8 amp @ 117 VAC / 5 amp @ 30 VDC.
