Reliable Power Supplies and Accessories for Secure Access Control
Your access control system is only as strong as its power source. When a locking mechanism drops offline, your building becomes vulnerable. We provide a comprehensive range of professional power supplies and accessories designed to keep your doors secure and your systems running smoothly.
Door Entry Online is founded by experienced installers with over 16 years of hands-on trade experience. We supply the exact robust, trade-quality power units we trust on our own sites. Whether you are a commercial property manager, a landlord, or a trade installer, we have the right hardware to support your security network.
The Backbone of Your Security System
A stable power feed prevents frustrating lock failures and false alarms. We stock a variety of units to match the specific voltage and load requirements of your access control hardware.
12V DC Power Units and 24V Systems
Different locking mechanisms require different power loads. We supply reliable 12V DC power units for standard magnetic locks, keypads, and electric strikes. For heavier industrial setups, our 24V options deliver the extra push needed to keep large gates and heavy-duty locks functioning perfectly.
Boxed Power Supplies with Battery Backup
Power cuts pose a massive threat to building security. If the mains power fails, fail-safe locks will drop open. To prevent this, we highly recommend our boxed power supplies. These metal-cased units house the main circuitry and provide enough space to fit a lead-acid backup battery. When the mains power drops, the battery instantly takes over, keeping your doors locked and your property secure until the electricity returns.
Essential Access Control Accessories
Building a complete access control network requires a few vital extras. We stock all the essential accessories you need to finish the job to a professional standard.
- Backup Batteries: Our sealed lead-acid batteries fit perfectly into your boxed power supplies. They provide hours of standby power to keep your system alive during an outage.
- Time Relays and Timers: Sometimes you need a door to stay unlocked during busy office hours and lock automatically at night. Our programmable timers wire directly into your power supply, giving you complete control over your daily lock schedules.
