dormakaba Cobalt Electric Lock Range: SL30SGL and SL30DBL Side Load Locks NZ

Side Load Electric Lock Technology for Modern Access Control

The dormakaba Cobalt electric lock range represents a professional-grade solution for access control installers and security specifiers across New Zealand. Built around a side-load bolt mechanism rated to 100kg, the Cobalt SL30SGL and SL30DBL are engineered for demanding door applications where reliability, door misalignment tolerance, and seamless integration with access control systems are non-negotiable. Whether you are specifying for a single-acting door or a double-acting application, the Cobalt range offers a purpose-built answer backed by dormakaba's global engineering pedigree.

The Cobalt SL30 Range: SL30SGL and SL30DBL

The Cobalt range centres on two core lock bodies - the SL30SGL for single-action doors and the SL30DBL for double-action door applications. Both models operate on 12-24VDC and include integrated bolt and door position monitoring as standard. The side-load release mechanism is rated to 100kg, and an automatic deadbolting feature ensures the lock re-engages securely after each access event.

A key differentiator across the entire Cobalt SL30 range is the built-in door misalignment correction of up to 8mm. This tolerance is critical in real-world installations where door frames shift over time or manufacturing tolerances introduce small gaps - situations where rigid bolt locks fail but the Cobalt continues to operate reliably.

Both models also support Fail Safe and Fail Secure operation, switchable by repositioning a single internal jumper. This flexibility allows the same lock body to be configured to the site's egress and safety requirements without ordering a separate SKU.

SL30SGL - Single Action Side Load Lock

The SL30SGL is designed for single-acting doors and can be mortice-mounted horizontally or vertically. For surface mount applications - including glass door installations - the SLA30SGL accessory kit provides the housing and dress plate components required for a clean, professional finish.

Key features of the SL30SGL include:

• Side load release rated to 100kg
• Door misalignment correction up to 8mm
• Automatic deadbolting with 10mm stainless steel bolt pin
• Integrated door and bolt position monitors
• Fail Safe / Fail Secure configurable via internal jumper
• Reverse polarity and transient protection
• Multiple re-lock attempts on failed engagement
• 12-24VDC operation

SL30DBL - Double Action Side Load Lock

The SL30DBL shares the same core architecture as the SL30SGL but is engineered for double-action door applications. The SLA30DBL accessory kit - including the SLA204J housing and SLA206J dress plate - provides surface mount capability for double-action and glass door installations. The same 100kg side-load rating, misalignment tolerance, and monitored outputs apply across both models, ensuring consistent system integration regardless of door type.

Cobalt SL30 Accessories

The Cobalt range is supported by a dedicated accessory suite designed to extend installation flexibility. These components are specified separately to allow installers to select only what is required for their particular door configuration:

• View our product - SLA206J Cobalt Dress Plate for SL30DBL

Long square hole strikes (SLA203H for SL30DBL and SLA213H for SL30SGL) are also available to complete the hardware package for rebated or square-edge door frames.

Fail Safe vs Fail Secure: Configuring the Cobalt for Your Application

One of the most practical engineering decisions when specifying an electric lock is the Fail Safe / Fail Secure configuration. Fail Safe locks release on power loss - appropriate for egress paths required by building codes to remain freely accessible in an emergency. Fail Secure locks remain locked on power loss - suited to server rooms, cash handling areas, and secure storage where unauthorised access during a power event is the greater risk.

The Cobalt SL30 range handles this at the hardware level via a single internal jumper, meaning the same lock can be reconfigured on-site if a specification changes post-installation. The New Zealand Security Association (NZSA) provides guidance on security hardware standards and best practice for commercial installations in NZ.

Typical Applications for the dormakaba Cobalt Electric Lock

The Cobalt SL30 range is well suited to a broad range of commercial and institutional access control applications, including:

• Office entrance and internal secure zone doors
• Glass door access points in retail and corporate environments
• Double-action swing doors in hospitality and healthcare
• Controlled areas requiring monitored door and bolt position feedback
• Retrofit installations where door frame misalignment is a known issue
