1600A-N1P 1.0 Introduction The Detcon Models 1600A-N1P is a “user-configurable” multi-channel alarm controller. The 1600A is configurable for up to 16 channels. Through the use of I/O modules the 1600A can receive analog inputs consisting of 4-20mA, and can alternatively poll serial sensors via RS-485 Modbus™ RTU. The 1600A-N1P controller uses a modular design approach that allows the user to customize the selection of stand-alone input and output modules.
1600A-N1P 2.0 System Configuration 2.1 Hardware Configurations The Model 1600A-N1P is a “user configurable” alarm controller platform. The basic 1600A-N1P Controller includes the NEMA 1 panel enclosure with Controller Module (including display), Power Supply, two AC and one DC breakers, and DC over-voltage protection module. NOTE: The I/O modules are factory installed unless specifically instructed otherwise. A maximum of two (2) I/O modules will fit on the standard N1P enclosure.

Modifications to the set-up configuration are expected to take place at the customer’s site due to requirement changes and/or system expansions. 2.
1600A-N1P 3.0 Installation Securely mount the Model 1600A-N1P enclosure on a suitable panel opening. The recommended opening cutsize is 9”W X 7.25”H and the required depth is 16”. 0.375" R0.109" 0.218" 10.5" Slot Detail 9.75" Model 1600A-N1P Multi-Channel Gas Detection Control System 2A 3.
1600A-N1P A B + RESET A B C NO NC Where applicable, connect the RS-485 wiring from remotely located I/O devices to the terminals located on the Back Panel. These terminals are labeled RS-485 “A” (+), “B” (–), and “Shld” (shield) for primary RS-485 communication (Figure 5). RS-485 wiring should consist of a two conductor, shielded twisted pair (Belden cable P/N 9841 is recommended). Also available are two output terminal blocks to provide 24VDC to external RS-485 devices.
1600A-N1P 3.1 1600A Interface Board The 1600A Interface PCA is connected to a set of Terminal Blocks on the DIN Rail (Figure 6 1600A Interface PCA and Figure 7 Interconnect Wiring Diagram.) The Terminal Blocks are labeled “NO COMM” “C”, “NO” and “NC”. The 1600A Interface PCA, mounted on the inside of the top panel of the enclosure, will de-energize the on-board relay in the event there is a ‘No Communication Fault’ condition with any activated device.

Note: the controller power supply is only capable of handling 3 Amps accumulative.
1600A-N1P Relay Output Contact Modules There are four ‘Form C’ 5 Amp relay contacts in each Model RL4 module. These can be used to fire annunciating devices or as signal inputs to other control devices. Connect to the relay contacts of the Model RL4 module as shown Figure 11. Note that the Amp rating of the relay contact should not be exceeded. Figure 11 Model RL-4 Relay Module 4-20mA Output Modules There are four 4-20mA outputs in each Model AO-4 module.
00A-N1P • Belden 9841 cable is recommended for a single cable providing serial communications only. Ground the cable shielding at the Model 1600A-N1P Controller only. Other points of grounding may cause a ground loop, and induce unwanted noise on the RS-485 line, which in turn may disrupt communications.

1600A-N1P 3.6 Setting Device Identification on the I/O Modules NOTE: If your Model 1600A controller has been configured at Detcon, you may elect to skip to the Operator Interface (Section 4.0) for further review of system operation. For a unit that has not been properly configured, the I/O modules must be serially addressed to establish correct communications. The I/O module’s identification is established by setting the two rotary switches to the correspondingly correct position.

1600A-N1P 7.0 Warranty Detcon, Inc., as manufacturer, warrants under intended normal use each new Model 1600A-N1P controller to be free from defects in material and workmanship for a period of one year from the date of shipment to the original purchaser. Should the controller fail to perform in accordance with published specifications within the warranty period, return to Detcon, Inc., for necessary repairs or replacement.
1600A-N1P Appendix A RS-485 System Integration Wiring RS-485 is a generic electrical specification only. It does not specify connector types, protocols, or cable type. It is the responsibility of the installer to provide a correct physical installation for the RS-485 network to function properly. RS-485 is very inexpensive and inherently rugged, allowing multiple devices to communicate over a single twisted pair of wires.
1600A-N1P in industrial environments, shielded twisted pair is required. Wiring of 24 AWG is highly recommended, but 18 to 28AWG can be used. The characteristic impedance of the cable must be between 100 to 120 ohms. Twisted pair is used because if the cable does run near a noise source both conductors will pick up the same amount of noise; therefore, effectively canceling it out.
1600A-N1P Figure 34 Recommended RS-485 communications set-up Grounding Another problem that can occur with RS-485 is incorrect grounding. Neither one of the two conductors in the cable is ground. Both of the conductors are supplying a current to maintain a voltage level relative to an external reference. A third conductor must be supplied to establish a reference through earth ground. RS-485 is specified be able to work normally with a ±7V ground potential difference and survive ±25V surges.
1600A-N1P Figure 35 Unbalanced Data Bus The addition of 2 repeaters (Figure 36) can solve this problem. The repeaters look like short stubs to the main bus, and at the same time they create 2 new buses that have all the same characteristics as the main bus. Each leg must have termination resistors to balance the new data bus. Figure 36 Data Bus using two repeaters Be sure to check the equipment being installed.
1600A-N1P Device Hook-Up Installation should begin by deciding where devices will be located and how the connections between devices and the master will be established. The ideal scenario would look like Figure 38. The example shows the 880 Controller connected to 11 slave devices using a daisy-chain wiring scheme. This would require 2 different twisted pair cables, one pair for power, and the other for the RS-485 data bus.
1600A-N1P In this case it is impossible to balance the data bus because there is no distinct beginning or end to the cable run. The best way to make this type of installation successful is to install repeaters in a few key areas as shown in Figure 40. Repeaters are used to eliminate the t-taps or stubs, which can cause communication problems. The location and number of stubs will dictate where repeaters need to be installed. Four repeaters are installed to eliminate the stubs.
