1.0 INTRODUCTION
Detcon Model 1610A Rack consists of 3 major assemblies:
1. The NEMA 1 rack mount control enclosure.
2. The single channel digital control modules.
3. The remote mount gas sensor assemblies.
The NEMA 1 control enclosure is detailed in section 1.0 of the manual, the control modules in
section, 2.0 and applicable sensor assemblies in section 3.0.
1.1 DESCRIPTION
Detcon Model 1610A along with Model 10A digital control modules is designed to serve as a
host assembly for up to sixteen 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 application flexibility wherein multiple function gas detection systems can be configured in any combination up to sixteen channels. All control modules are plugin front panel accessible for easy maintenance and repair.
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),
4-20 ma outputs for remote recording devices, alarm reset, and 24 VDC input.
Form C relay outputs may be discreet, zoned or common by gold plated jumper tabs located
on the controller mother board.

1.3 REMOTE RESET
The reset function is effective when the Model 10A's respective alarms have been programmed in the latching position and alarm conditions have passed. The alarm reset function is
common to all controllers and is activated by closing the circuit between the two reset contacts.
A normally open momentary switch is suitable.
1.4 INSTALLATION
01. Securely mount the 1610A rack enclosure in accordance with the drawing in figure 1.
02. Connect 24 VDC input wiring to the lugless terminal strip (labeled DC IN) on the back of the
controller mother board (see fig 2).
Caution: Observe correct polarity when terminating all input/output field wiring. Failure
to do so may result in circuit damage on power up.
04. If applicable, connect a normally open momentary remote mounted switch to the lugless
terminal strip (labeled RESET) located on the controller mother board (see fig 2).
05. Refer to installation and wiring detail of remote mount sensor assemblies as detailed in
section 3.0. Terminate field wiring from sensors to Model 1610A rack lugless terminal strips
located on the controller mother board (see fig 2).
Note: Based on the application and use of relay contact outputs, complete all wiring
terminations prior to application of power. Shut-in controls may be omitted until system
test is complete.
1.5 START-UP
Upon completion of all field wiring apply 24VDC power to the 1610A rack. Note that each
Model 10A controller digital display illuminates. Varying readings may occur during sensor
warm-up. A 10 second alarm delay will occur on power up. Refer to sections 2.0 and 3.0 for
additional start-up detail.
