Hardware Configurations
The Model 1600/6400-N1P is a “user configurable” alarm controller platform. The basic 1600/6400-N1P
Controller includes the NEMA 1 panel enclosure with Controller Module (including display), Power Supply,
AC and DC breakers, AC and DC over-voltage protection modules, and an RS-485 Isolated Repeater. NOTE:
The I/O modules are factory installed unless specifically instructed otherwise. A maximum of two I/O
modules will fit on the standard N1P enclosure. I/O Modules are purchased separately.
The available Detcon I/O modules include:
Model DA-4 – Four channel analog 4-20mA input module
Model RL-4 – Four channel relay output module
Model AO-4 – Four channel analog 4-20mA output module
Model DI-4 – Four channel contact input module
Detcon I/O modules are individually addressable and operate on 11.5-30 VDC. Each module communicates
with the controller via the RS-485 Modbus™ RTU protocol. Up to eight I/O modules can be mounted in the
main NEMA 4X enclosure; other modules should be mounted in separate enclosures. In many cases,
customers find it more convenient to mount the Model RL4 relay modules in the 1600/6400-N1P enclosure,
with the Model DA4 input modules mounted remotely, in a separate enclosure, near the gas sensors. This
simplifies the wiring between the gas sensors and the Controller. The following figure shows the typical
configurations of the 1600/6400-N1P controllers.

Programming Configuration
The 1600/6400 controllers are normally configured at Detcon based on application specific information
provided by the customer on the Configuration Form (See Section 13.0). It must be verified that the correct
quantity and type of I/O modules have been purchased to support the customer’s configuration requirements.
On the Configuration Form, the customer should supply all site-specific information pertaining to:
