Flexible Voltage and Low Energy Usage

The Alpro DB25 electric deadlocking bolt supports a wide range of voltage inputs (12V to 24V DC). Its intelligent microprocessor controls power consumption, substantially reducing heat generation and allowing the solenoid bolt to remain safely engaged. This low current consumption means minimal running costs, reduced environmental impact, and reliable operation.

This electric lock requires a PSU with a minimum of 2 amps, and its low power consumption means that an energy efficient power supply unit is ideal. RGL’s Enerflex range is up to 92% efficient.

The DB25 Alpro Electric Deadlocking Bolt Lock with Smart Access Control Built In

The Alpro DB25 electric bolt features a built in access control module, designed to work efficiently with modern security systems. 

• Adjustable Unlock Period: Choose from 0, 3, 6, or 9 seconds to control how long the bolt remains unlocked after access is granted. This helps manage the flow of people through the door.
• Auto-relock Function: If the bolt doesn't engage immediately, it will attempt to lock up to nine times over 18 seconds. The monitoring system confirms when the bolt successfully secures. This function is available for the fail safe model only.
• Anti-tailgating Protection: Once the door is opened and closed within the unlock time, the bolt instantly relocks. This prevents others from slipping through behind an authorised user.

A fails secure model of the DB25 solenoid lock is available as a special order. Instead of the auto-relock function, it features a multiple unlock function. The lock will make 5 attempts to unlock the door at 2 second intervals. If you require the fail secure model, please contact our team to enquire. 

Flexible Installation Across Door Types

The Alpro DB25 electric bolt offers flexible installation options, making it suitable for a wide range of door types and settings. It can be fitted horizontally or vertically into timber or metal frames, and is compatible with single or double action swing doors, as well as sliding doors.

However, it must not be installed with the bolt firing upwards from the floor, as this configuration is not supported.

Consider the Alpro DB25L if your door has alignment issues. It features an additional magnet to help pull the door into position. The DB25L is available as a special order, so please contact us for more information. Alternatively, the Trimec ES8100 V-lock is a stocked option designed to resolve similar misalignment problems effectively.
