Security Door Controls

Access control system power requirements are uniquely different from other systems. Unlike camera system power requirements, access control systems draw more current for locking hardware and during access control-related events. 75 – 85% of access control operating problems and technical support calls are due to power issues. Access control systems require steady and clean (filtered) low-voltage DC current with surge suppression to protect printed circuit boards and connected devices from damage due to dirty power (transients and voltage spikes). SDC power supplies have been developed specifically to help reduce power system issues and to support electric locks and access control requirements. Our hybrid design combines the efficiency of switching power supplies with the inductive load handling capability of linear power supplies in various 12/24 VDC current output capabilities and enclosure sizes. Filtering and output voltage regulation provide protection and ensure the longevity of all system components. The high performance, heavy-duty circuitry is ideal for inductive loads and multi-door applications. 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.

• 632RFA: 2 Amp DC power controller with large cabinet
• 632RFL: 2 Amp DC power controller less cabinet

Applications:

• Fire/Emergency Release Input: A fire alarm input provides simultaneous release of all fail safe locks and door holders in case of an emergency. An optional manual reset switch following a fire/emergency release or power loss is available to meet code compliance. When the optional manual reset feature is required, should an AC power loss occur or the emergency release input be actuated, personnel must restore secondary output power manually at the power supply after the emergency release signal is reset and/or AC power is restored.
• Isolated Battery Charging Circuit: A separate charging output provides 13.5 or 27 volts to fully charge the batteries. The secondary output is always precisely maintained at 12 or 24VDC to protect locking devices and components from over voltage while the batteries are charging. The specified secondary output current is also maintained while batteries are charging. Derating of the secondary output current is not required when charging batteries.
• Low Battery Disconnect: Batteries are disconnected from the output circuit prior to deep discharge preventing battery destruction. Batteries are not included and should be ordered separately.
• Door Control Modules: Door control relay modules are available to meet virtually any application need. All wiring for lock hardware, access controls,remote controls and monitoring is terminated at one central location. Installation and troubleshooting is simplified. Modules may be factory installed or ordered separately for field installation as needed. Cabinet enclosures are preconfigured with mounting holes to accommodate door control modules. All modules are individually fused for protection of multiple station systems.
• Input and Output Surge Protection: Input and output surge protection is built-in. The AC input voltage is circuit breaker protected and the outputs are PTC protected.
• Visual Status Indicator (LED): LED tri-color status indicators provide information regarding the AC input, DC output and battery backup status.
• System On/Off Switches: Optional System On/Off switches are available both inside the cabinet enclosure or on the cabinet enclosure cover.
• 6' Power Cord: An optional 6’ power cord simplifies installations that do not require conduit where permitted by code.
• Key Lock Cover: Optional key lock cover available where tamper-resistance is required.
• International Standard Input: Additionally an alternative 230VAC international standard input is an available option.
