Smoke damper control interface improves energy efficiency
Protec has developed a smoke damper interface that utilises the integrity of its Fire Detection & Alarm (FD&A) systems to allow the wiring loop to also provide the management for all the smoke dampers in an installation, as part of it’s ‘integrated smoke damper’ system.
With the recent introduction of revised standards for healthcare premises (HTM-05) requiring the installation of many more smoke dampers located in fire compartment boundaries, this development should be of interest to many M&E installers.
By utilising the FD&A system to link the control and activation of the dampers, the need for an independent is removed. Even the power supply to the dampers that are typically supplied by individual 240V spurs - one for each damper - is eliminated, being replaced by Protec 24V battery chargers, each of which provides power to around 20 dampers. This offers cost savings in associated hardware such as cabling, distribution boards, and separate management control panels, which are not required
Protec has also developed a logic switching interface as part of the smoke damper control system. This detects the switched state of the associated critical dampers, closing them when necessary to prevent dangerous pressure build up within the air handling unit plant. It also incorporates several maintenance functions including a self-test function that allows each smoke damper actuator to be automatically tested. The results are recorded within a searchable log.
The system employs a simple user-friendly graphics interface, with protocols that allow the building’s BMS system to accept all fire alarm and smoke damper status information and permit override control of smoke dampers, if required.
