Installation and Specification
1. General:
The SI-16 sub-controller provides sensor interface and output controls for system integrators in
security/access control and other application. The controller has 16 input channels for supervised contact
monitoring and 2 form-C contacts for load switching. In addition, 2 digital inputs may be used for tamper
and UPS status monitoring. The sub-controller requires either 12Vdc or 12Vac for power.

2. Supply Power to the Interface:
The sub-controller accepts either 12Vdc or 12Vac for power. Locate power source as closed to the unit
as possible. Connect power with minimum of 18AWG wires.
Observe POLARITY for 12Vdc application!
3. Communication Wiring:
The SI-16 communicates to host via a RS-485 interface, which may be configured for either 2-wire or 4-
wire operation. The interface allows multi-drop communication on a single bus of up to 4,000 feet (1,200
m). Use twisted pair(s) (minimum 24 AWG) with shield for the communication.
Install the following jumpers for the RS-485 interface according to the selected configuration:

4. Alarm Inputs Wiring:
Inputs 1 to 16 may be configured to use or not to use End of Line (EOL) resistors and to use normally
open or normally closed contacts. Input CT and input BA are typically used for monitoring cabinet tamper
and power failure respectively. These two inputs are for contact closure monitoring only, and do not use
EOL resistor(s).
5. Relay Outputs:
The following show typical use of the relay outputs. DC source is recommended whenever it is possible.
Transient clamping must be provided to protect the contact and to reduce EMI emission. Use sufficiently
large wires for the load current to avoid voltage loss.

6. DIP Switch Usage:
Switches 1 to 5 select the devices communication address. Switches 6 to 7 select the communication
baud rate. Communication on the RS-485 serial port is asynchronous, half-duplex with 1 start bit, 8 data
bits and 1 stop bit.
