Power centres

by Mark Rowe

Dantech Electronic Engineering, the UK manufacturer of power supplies and ancillary equipment for security applications, report that it’s promoting faster, neater and lower-cost Paxton Net2 installations with its DA481 and DA482 integrated Access Control Power Centres.

Supporting installers’ profitability by reducing equipment and mains cabling costs, Dantech Power Centres provide 12v DC switch-mode power for either two (DA481) or four (DA482) Paxton Net2 PCBs. The power supply module provides two sets of outputs for each controller position: 500mA for the controller and 2A for lock power. All outputs are protected by self-resetting fuses and equipped with status LEDs. With only a single fire alarm input required to the Power Centre, lock power outputs are individually selectable as either continuously powered or fire-switched.

Two (continuously charged) VRLA battery packs up to 12Ah can be mounted in the Power Centre, for continuity of security in the event of a mains power failure. Mains and battery status can be monitored via volt-free contacts, and batteries are protected by automatic deep-discharge disconnection. As for physical security of the Power Centre, it has key-lockable and tamper-protected steel enclosure.

As for installation, with just one fused spur required for each Power Centre instead of one per door controller, electrical installation costs are the makers say reduced, and mains cabling can be completed more quickly. Equipment mounting, connection and commissioning also require less engineering time, and ongoing maintenance will be both simpler and more economical for the life of the system, according to the firm.

Available from distributors, Dantech Power Centres can be fitted for two or four Net2 access control units, whether centrally or at convenient locations around a protected site.
