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.
This manual is intended for use by qualified, authorized engineers and technicians who are responsible for meeting a UL 864 project specification. The specification, created by the smoke control system designer, should have already considered the selected mechanical equipment design. Proper duct sizing and layout, motor/blower selection, and damper selection must be completed by the smoke control system designer to provide the planned smoke control pressurization under all possible expected environmental (for example, wind and weather) and building (such as door, elevator hoistway, leakage, system response, stairwell, and occupied mode) conditions.
