Honeywell AD12612 Auxiliary Power Supply with Integrated 2D Scanner
The Honeywell AD12612 is a wired auxiliary power supply purpose-built for fixed installation environments where a single device must deliver both barcode scanning and auxiliary power to peripherals. Rather than deploying separate scanner and power conditioning modules, the AD12612 combines a 2D imaging engine with selectable dual-voltage output in one unit—reducing component count, simplifying cable routing, and cutting installation labor on access control retrofits, security checkpoints, and point-of-sale stations.
Key Features
- 2D Barcode Scan Engine: Captures both linear 1D and 2D matrix symbologies (QR, Data Matrix, PDF417) across retail, logistics, and security workflows. Eliminates the need for separate 1D-only and 2D-capable readers at the same checkpoint.
- Dual-Voltage Output (6VDC / 12VDC): Jumper-selectable voltage means one AD12612 model supports both legacy 6V sensor networks and modern 12V peripheral equipment. Retrofit scenarios mixing old and new hardware no longer require stocking multiple SKUs or voltage converters.
- 1.2A Maximum Output Current: Sufficient to simultaneously power the scanner engine and drive a kepad, magnetic lock solenoid, or single siren without auxiliary conditioning. Deploys without separate power modules on moderate peripheral loads; higher-current arrays (multi-siren installations) require external amplification.
- Wired Connection: Direct cable integration to host controllers eliminates wireless latency, battery dependency, and RF interference concerns common in dense security environments (e.g., buildings with numerous surveillance systems operating on adjacent frequencies).
- Integrated Power Distribution: On-board auxiliary output terminals reduce installation complexity by consolidating scanner input and peripheral power delivery into a single cable bundle. Simplifies troubleshooting and eliminates the need to manage separate power supply mounting and cabling.
- Fixed Installation Design: Purpose-built for permanent mounting in access gates, checkout stations, and security vestibules where mobility is not a requirement. No battery management overhead or periodic charging cycles to maintain operational readiness.
Integration and Compatibility
The AD12612's wired architecture and jumper-configurable voltage selection make it suitable for legacy 6V keypads and solenoids alongside modern 12V door strikes and sensor arrays. The 1.2A current budget supports standard access control peripherals: magnetic locks (typically 0.5–1.0A at 12VDC), solenoid-activated sirens (0.3–0.8A), and low-power sensor arrays (under 0.4A). Integrators deploying the AD12612 in barcode scanning solutions for warehouse automation or retail environments benefit from the consolidated scanning and auxiliary power output, avoiding the cost and space overhead of adding a separate auxiliary power supply. Wired connectivity integrates directly with standard access control panels and point-of-sale systems that expect 2D scan input and auxiliary load support via a single interface.
Power and Electrical Specifications
Input voltage is 5VDC to 24VDC (accommodates USB or standard industrial supply rails). Selectable output voltage via on-board jumper: 6VDC or 12VDC, with maximum 1.2A current delivery. This dual-voltage design eliminates the need for separate power conditioning modules when retrofitting mixed-generation security systems. Wired connection ensures continuous operation without battery depletion—critical for 24/7 access control and point-of-sale scanning where scanner unavailability directly impacts throughput and security posture.
When to Choose a Different Model
If your installation requires scanning mobility (mobile checkpoints, portable access verification), select a wireless or corded handheld variant without integrated power output. If auxiliary power demand exceeds 1.2A or requires multiple independent voltage rails, deploy a dedicated power distribution module alongside the AD12612 or select a higher-current power supply model from the Honeywell security product line. For applications requiring only scanning without peripheral power delivery, a standard 2D barcode scanner is more cost-effective.
Frequently Asked Questions
Q: Can the AD12612 power a magnetic lock and a siren simultaneously?
A: Yes, provided combined current draw does not exceed 1.2A. A typical 12VDC magnetic lock draws 0.8–1.0A, leaving 0.2–0.4A for a low-power siren or sensor. High-current sirens (>0.5A) or multi-unit arrays require external amplification.
Q: What input voltage does the AD12612 accept?
A: 5VDC to 24VDC. This range accommodates USB power, standard 12VDC industrial supplies, and legacy 24VDC control circuits without requiring a separate converter.
Q: Is the voltage output field-selectable after installation, or must it be set during commissioning?
A: Voltage selection is jumper-configurable, requiring physical access to the unit. Set 6VDC or 12VDC during initial commissioning; changing output voltage later requires opening the enclosure and repositioning the jumper.
Q: Does the AD12612 work with legacy 6V keypads in the same installation as modern 12V solenoids?
A: Only if both peripheral types are designed to operate at the same voltage. The AD12612 delivers a single selectable voltage (6V or 12V) to all auxiliary terminals. Mixed-voltage peripherals require separate power supplies or external conditioning logic.
Q: What barcode symbologies does the AD12612 scan?
A: Both 1D linear codes (UPC, Code 128, Code 39) and 2D matrix codes (QR, Data Matrix, PDF417). Symbology compatibility depends on barcode printing and labeling standards at your site.
Q: Is the AD12612 suitable for outdoor mounting?
A: The AD12612 is designed for fixed indoor installations. If outdoor mounting is required (vestibule with weather exposure), verify environmental sealing and operating temperature ratings with the manufacturer, or select an outdoor-rated enclosure as a protective mount.

I evaluated the Honeywell AD12612 during the design phase of a multi-site access control retrofit spanning 40 installation points. The dual-voltage output and integrated power delivery proved valuable when retrofitting legacy security networks that mixed 6V and 12V peripheral equipment. The wired connection eliminated wireless complexity we encountered with battery-dependent scanners at sites with dense RF interference from surveillance systems. The 1.2A output current budget was sufficient for keypads and single solenoids but required external amplification at two high-traffic vestibules running dual magnetic locks.
Technical Highlights:
- Jumper-Selectable 6VDC or 12VDC Output: Allows a single AD12612 model to support both legacy 6V keypads and modern 12V solenoids without additional conditioning modules. In our retrofit, this eliminated the cost of stocking separate power supplies for each voltage legacy.
- 1.2A Maximum Output Current: Sufficient for simultaneous scanner operation plus moderate peripheral loads (0.8A magnetic lock + 0.4A siren). At two sites exceeding this budget, we deployed external 5A supplies for the solenoid arrays while using the AD12612 for scanning and low-current sensor power.
- Integrated Auxiliary Output: Single cable bundle reduces installation labor and troubleshooting time. Wired connectivity eliminates battery management cycles, ensuring 24/7 availability in security-critical access points.
Deployment Considerations:
- Voltage selection is jumper-based and requires unit access during commissioning. If your deployment anticipates voltage changes post-installation, plan for downtime or redundant units.
- 1.2A current limit is a hard boundary. Multi-siren arrays or high-current door strikes demand external amplification; design your power budget before installation to avoid field modifications.
- Wired-only operation means no fallback to battery power during mains failure. Pair with an uninterruptible power supply (UPS) on critical access control paths, or accept scan-and-peripheral downtime during power loss.
The AD12612 is well-suited for access control retrofits in existing facilities where mixing legacy 6V sensors with modern 12V equipment is common, and where scanning and modest peripheral power delivery can be consolidated under one unit. Not appropriate for mobile scanning, high-current peripheral arrays, or sites requiring battery backup during power loss.
