This section provides recommendations on minimum wire sizes (cross-sectional areas) and maximum wire lengths for the wires connected to the screw terminals of Central IO modules, AS-B servers, RP and MP controllers, and IP-IO modules. Recommendations on minimum wire size and maximum cable length for the digital inputs of the RP controller expansion modules, the DALI bus of the DALI light modules, the SMI Interface of the SMI blind modules, the Zigbee DALI and 0-10V modules, and the KNX Modbus gateway are also provided. The recommendations are for guidance only. Other wire sizes and lengths may be used, depending on wiring rules and when appropriate.
A backplane board is mounted in the terminal base for the W1 width devices. The backplane board is equipped with two 2x5-pin bus connectors, a 2x6-pin electronics module connector, address logic circuitry, and a device label.
The terminal bases are used for SpaceLogic devices that are based on the patented two-piece design. The terminal base provides the I/O bus to the electronics module installed on the terminal base as well as to the SpaceLogic device installed to the right (next terminal base in the chain).
You must install most of the controls products listed here in an enclosure that meets the following minimum criteria. After the criteria, several specific enclosure models are listed as examples of enclosures that meet the minimum criteria you can use for the smoke control system.
Using the power rating for each of the modules (listed in the following table), accumulate the power consumed by the Smoke Control Server and Central IO modules. The PS-24V can supply up to 30W (~1.25A at 24 VDC). The 24 VDC from the PS-24V is delivered to all modules connecting on the bus on the right side of the PS-24V up to the next power supply module. You must add another PS-24V on the I/O bus to keep the load on the previous power supply at 30W or below.
Use the power budget to calculate the maximum number of devices that the power supply can supply. If more devices are used, additional power supplies must be added to the I/O bus.
The Status LED on the front of the automation devices changes color and flashes to indicate the status of the device.
The UI-8/DO-FC-4 and UI-8/DO-FC-4-H Central IO modules combine 8 universal inputs and 4 digital Form C relay outputs.
The DO-FC-8 and DO-FC-8-H Central IO modules are digital output, Form C relay, 8-channel I/O modules.
