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.
The MP-C controller and IP-IO module, which are based on the same hardware platform, are installed using either of two methods: they can be snapped onto a DIN rail or screwed onto a flat surface inside a cabinet.
The Central IO modules all use the same model TB-IO-W1 terminal base model. You install the Central IO modules on the terminal base as follows:
Other than responding to the initial fire alarm in an attempt to localize and minimize smoke migration, the other primary function of a smoke control system is to provide the firefighters with a means of overriding and controlling selected portions of the HVAC system (dedicated and non-dedicated equipment). The conditions in a facility can change significantly subsequent to the initial alarm signal. When firefighters arrive at the scene, it is desirable to provide them with the necessary controls to revise the smoke control system operation. This must be presented to the firefighters in a form that can be easily interpreted and operated to permit them to direct the smoke control response after that initial alarm. Within a listed smoke control system, the override capability for firefighters is accommodated with the provision of a Firefighter's Smoke Control Station (FSCS).
Each controller managing smoke control equipment that is of sufficient size/importance to be displayed on the FSCS panel must also validate the operation of the equipment. When the equipment is non-dedicated, the normal HVAC applications will allow detection of equipment faults. The controller must use proofing sensors to confirm the fan is moving air, or the position of dampers has reached the intended position.
These restrictions are associated with the application of BACnet/IP controllers to UL 864 smoke control systems. They take precedence over existing product literature and are required for compliance with the UL 864 Listing.
The tables that follow provide a summary of all the equipment models you can interconnect to form the smoke control system.
EcoStruxure Building Management for smoke control includes a wide variety of hardware controllers, Central IO modules, and a family of software products. EcoStruxure Building Operation refers to the software running in the Smoke Control Servers, Enterprise Servers, Report Servers and Workstations. The EcoStruxure BMS is an integrated solution for building management that combines environmental control, energy management, energy monitoring/metering, alarm management, security and reporting. The system can be customized for building management applications extending from small office buildings to skyscrapers and office, school, or industrial campus environments.
The HVAC system manages the operation of the Heating, Ventilation and Air Conditioning (HVAC) equipment serving the controlled spaces within a facility.
Terminal connections for the following Central IO modules are described here:
