ESCRIPTION
Detcon Model 410-N1 along with Model 10B digital control modules is designed to serve as a host assem-
bly for up to four remote mount gas detection sensor assemblies. The control enclosure is rated NEMA 1
suitable for installation in non-hazardous locations. The single channel modular design supports applica-
tion flexibility wherein multiple function gas detection systems can be configured in any combination up
to four channels. All control modules are plug-in front panel accessible for easy maintenance and repair.
The control enclosure houses a modular power supply (Model PS100-10B) which includes, as standard
operating controls, a power on/off switch and a line power fuse.
Discreet output terminal strips located on the controller motherboard are provided for sensor terminations,
Form C dry contact alarm outputs (normally open, normally closed and common) for two alarms plus

are provided for VAC power in, VDC power in, and remote alarm reset.
Form C relay outputs may be discreet, zoned or common by gold plated jumper tabs located on the con-
troller mother board.
