Choosing the Right Power Supply

Securing facilities is a top priority for any business or organisation. Access control plays a key role in achieving this goal. It's essential to choose the right power supply unit with the correct amperage to support all the components of your door entry system effectively. 

Each door equipped with access control devices, such as electronic locks and proximity readers, requires a reliable power source to operate smoothly. By selecting the correct power supply for your needs you can ensure optimal performance. This minimises the risk of system failure.

12V power supply units as well as 24V DC transformer rectifier power supplies for door closers are also available. Our Guide to Power Supply Units in Access Control Systems provides further information.

Benefits of Battery Backup

Ensuring an uninterrupted power supply is crucial for the security of a facility. It is especially important during power failures when the safety of the premises is at risk. Using battery backup becomes vital in these situations. It acts as a reliable backup plan to maintain the effectiveness of security measures such as electronic locking solutions. 

With battery backup, facilities can keep their doors secure and limit access to authorised personnel, even when the main power source is disrupted. Having the facility for battery backup in place gives facility managers confidence that their premises' security remains solid. It ensures peace of mind regardless of external power issues.
