Detex 81-800 Logic and Power Supply Controllers

Deliver consistent, secure power to your access control and security doors with the Detex 81-800 logic and power supply controllers. Designed for building security integrators and facility managers, this Detex access power controller converts standard 120VAC input into a regulated, filtered 24VDC output to protect sensitive electronics, support surveillance and monitoring systems, and ensure reliable latch retraction on exit devices. The 81-800 provides 1 AMP continuous output—ideal for one Detex latch retraction (ER) device—while the integrated battery charging circuit keeps emergency backup batteries ready (batteries sold separately). Filtered power and built-in surge protection minimize downtime and reduce maintenance on electrified door hardware and access control components. Packaged in a compact steel enclosure (12.3" x 12.3" x 3.5") and backed by a 3-year limited warranty, the 81-800 is a durable choice for commercial and institutional installations. Optimize your door security, fire egress, and monitored entry systems—order the Detex 81-800 today or contact us for a specification quote.
