Product Description

Flush-mount electric bolt lock, model 150A-NO, designed for access control systems on wooden, metal, or PVC doors. The NO (Normally Open) version is fail-secure: it remains locked when not powered and unlocks only when voltage is applied (POWER ON).

The electromagnetic design uses low-remanence materials for stable operation, while the compact body allows a discreet installation in the frame. It is compatible with access controllers, intercoms, exit buttons, and can provide status feedback through the signal wires.
