We Are Thankful

SDC would like to share our gratitude for an incredible 50+ years in the industry. We are particularly thankful for all of our hardworking employees, customers, partners, and SDC family over the years. As we move into this holiday season, we want to wish everyone a healthy and Happy Thanksgiving.

We recognize this day to honor and thank our nation's brave veterans who have served our country to fight for our freedoms. Thank you for your service. 

SDC Proudly Supports

1 – 6 Amp Access Control Power Supplies

In 1994 SDC introduced the 602 power controller – the first hybrid supply to combine the efficiency (low heat generation) of switching power supplies and the rugged inductive load handling capability of linear power supplies to meet the unique needs of access control locking devices. 

Unlike camera system power requirements, access control systems draw more current for locking hardware and during access control-related events. As the industry transitions from solenoid-based electric locking devices to motorized devices, demand for specific power supply requirements has also increased. 

SDC’s 12/24VDC class 2 hybrid power supplies have been designed specifically to meet these needs and reduce power system issues with extra filtering, heavy-duty circuitry for inductive loads and multi-door applications, and an isolated battery charging circuit to protect locking devices and components from over voltage while the batteries are charging. With the addition of SDC programmable controllers or relay modules, the user-friendly modular designs ensure versatility, interface capability and easy installation of virtually any electric locking devices, access controls and related fire life safety equipment.

Proven Delayed Egress Innovation...

See why our proven Delayed Egress solutions have led the industry since 1995 with the most choices and customization available. Also, learn why SDC has been the premier manufacturer of popular electrified access control hardware like bolt locks, strikes, EMLocks® and egress devices - all Designed, Engineered and Built in America since 1972, while most of our larger competitors manufacture overseas.

Back to Basics: Electric Strikes

In 1982, SDC’s first electric strike design initiated the adoption of strikes by the door hardware industry. Then, we engineered the UniFLEX™ 45 and 55 series – the first electric strikes with interchangeable faceplates and field reversibility for failsafe or failsecure operation. The interchangeable design of these strikes allows SDC to also provide multiapplication strike kits that include one electric strike and three faceplates to meet common applications, making them easy to stock and maintain in inventory.

Today, our strikes integrate with a broad range of mechanical locksets, devices, door and frame styles and budgets. Since 1972 SDC products have been designed, engineered and built in America to provide quality products that are readily available.

SES Generates the Most DoorSnap^TM Customer Submissions

Southeast Security Products (https://sesproducts.com), located in Deerfield Beach, Florida, earned year-long bragging rights among SDC’s Door Hardware and Alarm/Electronic Security outside sales rep agencies. From June 1^st thru August 31^st SES promoted and received the most customer submissions – 18 - for DoorSnap^TM, our award-winning solution for recommending access control locking hardware for door retrofits.

DoorSnap^TM is included in our Free SDC App and allows customers to send a picture of their retrofit door installation and receive a complimentary access and egress electrified solution recommendation from SDC with product information links and more.

Concerning DoorSnap^TM, SES President, Roy Nilsen says: “We simply show DoorSnap^TM to every dealer we can. There is simply no easier way to give a dealer the confidence of specifying a door opening knowing you have the right hardware to get the job done right the first time. It saves dealers time and money and is the easiest value proposition we have in our tool bag…”

Rumor has it that Roy has already reserved a special spot in his display case for the electrified DoorSnap^TM trophy being shipped to him this week. When plugged in, the trophy is lit with a rotating palette of colors designed to subliminally encourage more sales on our behalf. Way to go Roy!

On this day we remember the victims lost in one of our nation's most horrendous tragedies. We honor them, their families, first responders, civilian heroes, and all impacted by the events of 9/11. As Americans, we will never forget. 

Electric Latch Retraction (ELR)

Since 2012, when SDC launched QuietDuo™ – the first Motorized ELR Kits to convert mechanical exit devices – we’ve been “quietly” leading in electric latch retraction (ELR) upgrades for access control. This includes retrofit solutions for most brands of exit devices, as well as innovative SDC exit devices & mortise lock-sets with factory-installed ELR and automatic door operators with a built-in 1 Amp+ power supply to power them.

With advancements in electric motor technology, the use of a motor for electric latch retraction provides lower current draw, quieter operation, and greater durability over time vs. solenoids.
