Choose fused outputs when you want individually protected circuits with a fuse-based protection method and straightforward fault isolation for locks and accessories. Choose PTC-protected outputs when Class 2, power-limited circuits with auto-resettable protection can help reduce service steps after an overload, while also considering the access control system’s voltage, current, and fire alarm interface requirements.

Select a module that matches the access control devices’ required voltage, with options in this assortment supporting 12 VDC, 24 VDC, or 12 to 24 VAC or VDC. Size the power capacity for the combined load of locks and accessories, using the module’s rated output current, such as 6 A or 10 A, and account for individually protected outputs when distributing power across multiple devices.

An access control system power module needs one independently controlled output for each lock, door accessory, or other device that requires separate activation or fail-safe and fail-secure operation. The assortment includes four- and eight-output modules, so choose the output count based on the number of controlled circuits and any planned expansion.

Look for access control system power modules with multiple independently controlled, fuse-protected or power-limited PTC outputs that support the voltage and devices in your installation, such as maglocks, electric strikes, and magnetic door holders. Integration features can include normally open or open-collector trigger inputs, selectable fail-safe or fail-secure operation, fire alarm control panel disconnect inputs, form C relay contacts, removable terminal blocks, and options for shared or separate power sources.
