Alpro EB250 Electric Bolt: Monitored and Fail Safe

The Alpro EB250 solenoid bolt provides dependable, high security for doors in busy or high risk areas. With a 1000kg holding force, it offers robust protection where controlled access is critical.

Dual monitoring of the door and bolt positions gives real time status updates for networked systems, helping you stay informed and in control. The automatic relocking function can be set to 0, 3, 6, or 9 seconds, giving you flexibility over how quickly the door secures after closing.

This unit includes built-in transient and reverse polarity protection, reducing the risk of electrical damage and extending its service life.

The EB250 operates as fail safe (power to lock), meaning it unlocks automatically if power is lost to allow safe exit.

Slim Design for Flexible Mounting Options

The Alpro EB250 slimline solenoid bolt is designed for installation across a wide range of door types and configurations. It’s suitable for both hinged and sliding timber and metal doors, including single and double action. 

This electric lock can be mounted vertically or horizontally and installed either in the door leaf or the frame, depending on site requirements. Please note that the Alpro EB250 electric door bolt is not suitable for floor mounted installations.

Its concealed mortice design and compact profile make it ideal for narrow profiles and applications where a discreet locking solution is needed.

Durable and Low Maintenance 

The Alpro EB250 solenoid bolt is a continuously rated solenoid that withstands repeated activations, ideal for environments with frequent door usage. 

The bolt mechanism is factory lubricated for lifetime use; no additional lubrication is necessary, making maintenance simpler. Periodic checks every six months are recommended by Alpro to inspect the power supply, wiring, and cleanliness around the bolt to aid continued reliability.

EB250 Solenoid Bolt: Power Supply and Setup Guidance

To make sure the Alpro EB250 electric bolt performs reliably, allow for at least a dedicated 2 amp DC power supply per bolt. Position the PSU as close to the bolt as possible to reduce voltage drop. This Alpro solenoid bolt is not suitable for use with AC transformers or rectifiers, as these can compromise performance.

Correct alignment during installation is essential. Make sure the circular magnet on the strike plate lines up precisely with the ‘S’ marked on the bolt face plate. The hole behind the strike plate must be clear of debris and deep enough to accommodate the full 14mm bolt throw. If the bolt rubs or catches during movement, it may not lock or unlock correctly.

We also supply a wide range of compatible access control products, including power supplies, relays, and keypads. For guidance on building a complete system, speak to our technical team for expert support.
