Viking Electronics CTGF-BKD Clock Controlled Relay Output Converter
Overview
The Viking Electronics CTGF-BKD is a conversion module that changes CTG (call-triggered gate) operations into a clock-controlled relay output device — giving integrators a path to time-based relay switching without replacing existing Viking CTG infrastructure. If your deployment requires scheduled relay events rather than call-triggered ones, the CTGF-BKD (often searched as CTGF BKD) inserts into that workflow cleanly. Viking Electronics designs and manufactures access control and communication systems for commercial and institutional environments; browse the full Viking Electronics catalog for compatible door entry and control hardware.
Key Features
- CTG-to-Clock Conversion: Repurposes existing CTG-based relay infrastructure for scheduled, clock-driven output — avoiding a full hardware swap when operational requirements shift from event-triggered to time-triggered control.
- Relay Output: Provides a dedicated relay output suitable for controlling door strikes, gates, or auxiliary loads on a time-based schedule rather than a call event, expanding deployment flexibility on existing access control systems.
- Two-Year Limited Warranty: Backed by Viking's standard two-year limited warranty — consistent with the manufacturer warranty coverage across the Viking product line.
Integration and Compatibility
The CTGF-BKD is designed to integrate with Viking CTG-series equipment. Before specifying this module, confirm compatibility with your installed Viking CTG model — consult the Viking door entry and control line or contact pre-sales engineering for application-specific guidance. For broader relay and control planning, review the access control planning resources available for this product family.
Frequently Asked Questions
Q: What does the CTGF-BKD actually do?
A: The CTGF-BKD converts CTG (call-triggered gate) operations on compatible Viking equipment to function as a clock-controlled relay output device, enabling time-scheduled relay switching instead of call-event-triggered switching.
Q: What is the warranty on the CTGF-BKD?
A: The CTGF-BKD carries Viking Electronics' standard two-year limited warranty.
Q: Is the CTGF-BKD compatible with all Viking CTG products?
A: The CTGF-BKD is designed for use with Viking CTG-series equipment. Confirm compatibility with your specific installed CTG model before ordering — not all CTG variants may be supported.
Q: Is this a standalone device or does it require a host Viking unit?
A: Based on its function as a conversion module, the CTGF-BKD operates in conjunction with a compatible Viking CTG host unit — it is not a standalone relay controller.
The CTGF-BKD comes up when a site is running Viking CTG door-entry hardware and the customer decides they want relay outputs on a clock schedule rather than tied to an incoming call event. That is the specific problem this module solves — not a general-purpose relay timer, but a purpose-built conversion that keeps existing Viking CTG infrastructure in place while changing the trigger logic.
Technical Highlights:
- Relay Output Mode: Shifts the CTG's relay from call-triggered to clock-driven, which is the key behavioral difference — you get scheduled gate or door-strike control without rewiring the panel.
- Two-Year Limited Warranty: Viking's standard two-year limited warranty applies to the CTGF-BKD, consistent with their broader access control and communication product line.
- Viking CTG Ecosystem: Designed to work within Viking's existing CTG product family — the conversion is hardware-specific, not a generic add-on compatible with third-party systems.
Deployment Considerations:
- Verify your installed CTG model is on Viking's confirmed compatibility list before ordering — the CTGF-BKD is purpose-matched to specific CTG variants, and assuming broad compatibility is a common spec mistake on these modifier modules.
- The evidence base for the CTGF-BKD is limited; request the current Viking install sheet directly from Viking's product support portal before commissioning to confirm wiring terminations and clock input requirements for your specific panel revision.
Best fit for facilities running Viking CTG-based entry systems that are transitioning to scheduled-access relay control — school bell systems, after-hours gate automation, or time-locked door strike applications where the CTG hardware is already in place.
