Altronix TEMPOA2XV 2-Door Occupancy Alert Control System with Enclosure
Overview
The Altronix TEMPOA2XV is a self-contained occupancy alert control system designed for two-door monitoring applications that require integrated strobe signaling, panic response, and local power distribution — all in a single pre-wired enclosure. Running on 220VAC/60Hz at just 0.25A draw, it is suited for international installations and facilities where 220V branch circuits are the standard. If you are managing occupancy compliance in retail environments, controlled-access corridors, or secure rooms where you need door-state awareness plus immediate visual alerting, the TEMPOA2XV packages the control logic and power supply into one enclosure rather than requiring you to piece together separate components.
The unit monitors two doors via dedicated sensor inputs and pairs each door with its own strobe trigger input and switched strobe power output — so each entrance gets its own independent alert loop. Four additional auxiliary DC power outputs extend capacity for supplemental devices such as magnetic locks, card readers, or door controllers without requiring a separate power supply in the same cabinet.
Key Features
- 220VAC Input at 0.25A Draw: At 220VAC/60Hz input, the TEMPOA2XV fits directly onto the 220V branch circuits common in international facilities and many industrial buildings in North America — no step-down transformer required, and the 0.25A draw keeps your panel load minimal even when running continuously.
- Two Independent Door Sensor Inputs: Each door sensor input operates independently, so a held-open condition or breach on Door 1 does not suppress or interfere with Door 2 monitoring. This matters in vestibule configurations where simultaneous door events need to be tracked separately.
- Two Strobe Trigger Inputs + Two Switched Strobe Power Outputs: Each door loop includes a dedicated strobe trigger input and a corresponding switched power output. This paired architecture means your strobes activate per-door rather than globally — useful when you need to direct occupants to a specific exit or signal staff at a particular entry point.
- 30W Dual-Voltage DC Output (12VDC/2.5A or 24VDC/1.25A): The onboard power supply delivers up to 30W, selectable between 12VDC at 2.5A and 24VDC at 1.25A. This range covers the majority of access control peripherals — 12V electric strikes and most readers pull well under 2.5A, while 24V magnetic locks drawing under 1.25A can be powered directly from the enclosure without a separate brick supply.
- Four Auxiliary Power Outputs: Beyond the strobe outputs, four auxiliary DC outputs distribute power to downstream devices. Running card readers, REX sensors, or a small door controller from these outputs keeps wiring consolidated inside a single enclosure and reduces the number of power supplies an installer needs to manage.
- Two Panic Trigger Inputs: Dedicated panic inputs let you wire panic hardware — duress buttons, emergency pull stations — into the alert loop directly. When triggered, the system can activate the strobe outputs as a visual distress signal without requiring a separate relay module.
- Compact Pre-Wired Enclosure (8.5" x 7.5" x 3.5"): The 8.5 by 7.5 by 3.5 inch enclosure is small enough to mount inside a server room, electrical closet, or above a drop ceiling. Having the transformer, control board, and power distribution pre-assembled in one box cuts commissioning time compared to rack-mounting individual components.
- Operating Range 0°C to 49°C: The specified 0 to 49°C operating range covers typical conditioned interior environments. This is an indoor unit — it is not rated for unheated mechanical rooms in cold climates or outdoor enclosures, so plan accordingly when selecting mounting location.
Integration and Compatibility
The TEMPOA2XV is designed to integrate with standard door contact sensors (magnetic contacts, door position switches) wired to its sensor inputs, and with conventional strobe/visual alert devices wired to its switched power outputs. The dual-voltage DC output accommodates the broadest range of access control peripherals. Panic inputs accept dry-contact signals from standard duress buttons or pull stations. Because the system operates at 220VAC, verify that your building's branch circuit and any conduit runs are correctly rated before installation — the 0.25A draw is light, but the voltage class determines conduit and wire gauge requirements under NEC or applicable local code. Consult your Altronix product line documentation for terminal wiring diagrams and input/output specifications before roughing in.
For deployments where occupancy control integrates with broader access control systems, the TEMPOA2XV's panic and door sensor inputs can be driven by controller dry-contact outputs, effectively making it a local alert and power distribution satellite for a larger system architecture. Pair this unit with appropriate access control power supplies when additional current capacity is needed beyond the onboard 30W output, or with door controllers to manage the access decision layer above this unit's signaling function. For planning the power distribution side of a multi-door deployment, review a power planning guide to size auxiliary loads accurately.
Frequently Asked Questions
Q: What is the input voltage requirement for the TEMPOA2XV?
A: The TEMPOA2XV requires 220VAC at 60Hz, drawing 0.25A. It is not designed for 120VAC input — verify your branch circuit voltage before installation.
Q: Can the TEMPOA2XV power 24V magnetic locks directly?
A: Yes. The onboard power supply is selectable between 12VDC at 2.5A and 24VDC at 1.25A (30W total). A 24V magnetic lock drawing under 1.25A can be powered directly from the enclosure. For locks with higher inrush or holding current, size a separate supply accordingly.
Q: How many doors can the TEMPOA2XV monitor?
A: The TEMPOA2XV supports two door sensor inputs, two strobe trigger inputs, and two switched strobe power outputs — one complete alert loop per door. It is a two-door system by design.
Q: Does the TEMPOA2XV include panic input capability?
A: Yes. The unit includes two panic trigger inputs that accept dry-contact signals from duress buttons or emergency pull stations, enabling strobe activation as a visual distress signal without a separate relay module.
Q: Is the TEMPOA2XV suitable for outdoor or unheated enclosure installation?
A: No. The specified operating temperature range is 0°C to 49°C, which covers conditioned interior environments. It is not rated for outdoor installation or unheated spaces where temperatures fall below freezing.
Q: What are the physical dimensions of the enclosure?
A: The enclosure measures 8.5 inches wide by 7.5 inches tall by 3.5 inches deep — compact enough for electrical closets, server rooms, or above-ceiling mounting locations.
The TEMPOA2XV is one of those units that earns its place on a job when the alternative is mounting four separate components — a transformer, a control board, a power supply, and a relay module — in a closet with limited real estate. At 220VAC input and 30W DC output, it is specifically sized for international builds and 220V-standard facilities where sourcing a 120V-native Altronix variant would mean adding a step-down transformer anyway.
Technical Highlights:
- Dual-Voltage Output (12VDC/2.5A or 24VDC/1.25A): The 30W output budget covers a magnetic lock and a reader on a single door without an external supply — the 24VDC/1.25A mode handles most 24V strikes cleanly, and 12VDC/2.5A covers the majority of 12V reader/REX combinations.
- Per-Door Strobe Architecture: With two independent strobe trigger inputs and two switched strobe outputs, each door gets its own alert loop. This is the right design for vestibule and mantrap configurations where a global strobe would be ambiguous to responding staff.
- Four Auxiliary Outputs: Beyond the two strobe outputs, four additional DC outputs consolidate peripheral power inside a single enclosure — reducing the number of power supply locations an installer needs to service or troubleshoot after commissioning.
Deployment Considerations:
- Confirm branch circuit voltage at the installation location before ordering — the TEMPOA2XV is 220VAC only. Substituting it into a 120VAC circuit will damage the unit.
- The 0°C lower operating limit means this unit is not appropriate for unheated mechanical rooms in cold climates. If your closet drops below freezing seasonally, specify a unit with a lower temperature floor or add environmental controls.
This unit is the right call for a two-door occupancy alerting deployment in a conditioned interior space — retail backroom entries, pharmacy dispensary doors, or controlled-access server room vestibules — where the installer needs consolidated power distribution and per-door strobe signaling without building a custom panel from discrete components.
