Sdc 1581SNDV Delayed Egress Electromagnetic Lock

Product Description

The SDC Security Door Controls 1581SNDV is a delayed egress electromagnetic lock designed for controlled exit applications in commercial and institutional facilities. The unit holds a door magnetically and introduces a timed delay before releasing, giving personnel or monitoring systems time to respond before egress is permitted. An integrated audible tone alerts occupants and staff during the delay period. This type of device is typically installed by licensed electricians or low-voltage access control technicians working to applicable fire and life safety codes.

The 1581SNDV is suited for interior egress doors in commercial buildings, healthcare facilities, schools, and similar occupancies where delayed egress is permitted under the local adopted building and fire code. It is installed at single doors requiring controlled exit management without full access control hardware. The audible tone feature supports code-required notification during the delay sequence before the lock releases and allows egress.
