NTRODUCTION
The Detcon Model 1010SS-N4X consists of 3 major assemblies:
• The NEMA 4X (304 stainless steel) control enclosure.
• The Model 10 single channel digital control modules.
• The remote mount gas sensor assemblies.
The NEMA 4X control enclosure is detailed in Section 1.0 of this manual, control modules in Section 2.0 of the
Detcon Model 10 “Single Channel Digital Control Module” manual, and applicable sensor assemblies in Section
3.0 of the Detcon Microsafe “TP-524C Hydrogen Sulfide Sensor” manual.

ESCRIPTION
This Detcon Model 1010SS-N4X control enclosure, along with Model 10 digital control modules, is designed to
serve as a host assembly for up to ten remote mount gas detection sensor assemblies. The controllers provide out-
puts to drive din-rail mounted relays that trigger strobes, horns, and provide dry contact outputs to a remote DCS.
The control enclosure is rated NEMA 4X, which is by definition rain tight, and therefore suitable for outdoor loca-
tion in electrically non-hazardous environments. The enclosure can be used for many different applications. It pro-
tects internal equipment against splashing water, seepage of water, falling or hose directed water and severe external
condensation.
Construction features include:
‹ continuously welded seams, finished smooth
‹ robotically applied urethane gasket
‹ continuous stainless steel hinge with removable pin
‹ stainless steel captive clamps
‹ hasp and staple for padlocking
‹ door and body stiffeners
‹ external mounting brackets
‹ front door viewing window
‹ stainless steel hub entries
The single channel modular design supports application flexibility wherein multiple function gas detection systems
can be configured in any combination up to ten channels. All control modules are plug-in front panel accessible
for easy maintenance and repair. The system is powered by VAC line power and/or 24VDC unless otherwise speci-
fied at time of order.
The control enclosure includes a panel mount circuit breaker that also acts as a power switch. Discrete output ter-
minal strips located on din rails, provide connections for sensor terminations, power input, and dry contact relay
outputs. The 115VAC input is protected with a 20A circuit breaker. The sensor terminations utilize a blade type
terminal on the power connection to allow disconnection of power to individual sensors. All relay outputs have
fuse terminals to protect the equipment connected to them.
