About
Lay out every door, check the power, hand over the bid.
Access Design Pro lets an access-control technician walk a building and lay out every opening — reader, lock, request-to-exit, controller and power — then hand the customer a bid-ready proposal before leaving.
Review power-supply load, standby battery and reader-distance calculations as you design each opening. Verify voltage drop, controller limits and egress requirements separately.
WHAT IT DOES
• Every opening laid out on the floor plan
• Reader, lock, request-to-exit, controller and power per door
• Review power-supply load and standby-battery sizing
• Review Wiegand and OSDP reader-distance findings
• Surface egress items for technician review; confirm applicable code and AHJ requirements
• Good / Better / Best options and a full bill of materials
• Field photos and notes attached to the openings
• Branded PDF proposal, generated on device
BUILT FOR THE FIELD
Works entirely offline. Nothing leaves the device unless you send it.
WHO IT IS FOR
Access-control and security integrators who quote openings for a living.
From Low Volt Labs LLC — tools built by a technician with forty years in the trade.
