ASSA ABLOY 835C50 Handle Controlled Motor Lock

The Assa Abloy 835C-50 is a high-performance electromechanical lock case designed for modern security applications. Featuring both a deadlatch and an auto hook bolt, it delivers superior holding force by engaging automatically when the door closes—ensuring robust security while still permitting manual disengagement via handle operation. Engineered for adaptability, this model supports both split and fixed spindles, and can be reconfigured easily, making it versatile for various door setups. Constructed with durability and safety in mind, the 835C-50 is stainless steel finished and certified to meet key standards like EN 179 for escape routes, EN 14846, SSF 3522 class 3, and BS EN 14846 for mechanical lock performance. It supports both fail-safe and fail-secure operations, making it suitable for fire doors and emergency exits. It's construction includes features like drill protection and low power consumption, contributing to longevity and reliability in frequent-use environments. Installation and operation are streamlined with built-in intelligence and connectivity. The 835C-50 integrates with the Hi-O bus system via the I/O Box 350, enabling functions such as status monitoring, re-entry through alarm signals, and simplified setup via DIP switches for programming and configuring behaviours like auto hook control and override opening. Power-efficient, it operates on 12–24 V DC, with modest current draw even during latch or hookbolt operation. Altogether, the 835C-50 presents a secure, flexible, and intelligent locking solution for contemporary access control systems.
