Altronix TEMPOA2X 2-Door Occupancy Alert and Power Management System
Overview
The Altronix TEMPOA2X is a self-contained occupancy alert controller and power supply built for small commercial spaces where you need to enforce capacity limits, trigger strobes, and manage door sensors from a single enclosure — without wiring back to a full access control panel. Designed for retail locations, healthcare waiting areas, and compliance-driven lobbies, the TEMPOA2X consolidates door monitoring, strobe control, panic input handling, and regulated DC power into one UL-listed steel enclosure measuring 8.5" x 7.5" x 3.875".
For integrators evaluating Altronix power and control solutions, the TEMPOA2X sits in the occupancy alert line — a narrower product class than Altronix's broader power supply catalog, purpose-built for capacity-monitoring deployments rather than general access control.
Key Features
- Dual Door Sensor Inputs: Two dedicated door sensor inputs let you monitor entry and exit points independently. Pair with magnetic contacts on a two-door vestibule and the controller tracks occupancy state without any additional logic board.
- 2 Strobe Trigger Outputs + 2 Panic Inputs: Each door position maps to its own strobe trigger, so a red/green indicator at the entrance can switch state based on real-time door status. The two panic inputs provide a direct hardwire path for staff override buttons — no relay splicing required.
- 30W Regulated Power at 12VDC/2.5A or 24VDC/1.25A: The onboard power supply delivers 30W selectable between 12VDC and 24VDC output. That covers most strobe assemblies, door contacts, and low-current readers without a separate power distribution panel. Running 24VDC? You get 1.25A — enough for two or three peripheral devices depending on draw.
- 2 Switched + 4 Auxiliary Power Outputs: The switched outputs cut power to connected devices on trigger events, while the four auxiliary outputs provide always-on DC rails for sensors and indicators that need continuous power. This separation prevents nuisance resets on devices that shouldn't cycle during an alert.
- Battery Backup Ready: The enclosure supports sealed lead acid or gel-cell batteries (sold separately), keeping the system operational during a power interruption. For a compliance-driven occupancy system, losing power at a controlled entry is a liability — battery backup closes that gap.
- 115VAC / 60Hz Input at 0.5A: Draws half an amp from a standard 115VAC circuit. A single 15A branch circuit can support multiple TEMPOA2X units, which matters in retrofit deployments where running new circuits is expensive.
- 0°C to 49°C Operating Range: Rated for standard indoor commercial environments. The 85% RH tolerance (±5%) covers humid lobbies and vestibules without requiring additional climate control.
- Steel Enclosure with Knockouts: The 8.5" x 7.5" x 3.875" steel enclosure provides physical security for wiring terminations. Ships at 5.45 lb — light enough for single-person wall installation.
Integration and Compatibility
The TEMPOA2X operates as a standalone controller and does not require a networked access control platform to function. Door contacts, strobe assemblies, and panic buttons wire directly to the unit's terminal blocks. For deployments that need centralized monitoring, the switched outputs can signal a parent panel or NVR alarm input on state change. Battery type is field-selectable between sealed lead acid and gel cell — match your facility's existing battery standard to avoid mixed inventory.
When planning a multi-door deployment beyond two points of entry, evaluate Altronix's higher-input-count models in the same occupancy alert family — the TEMPOA2X is scoped to two doors and won't scale beyond that without adding additional units.
Frequently Asked Questions
Q: What is the output voltage of the TEMPOA2X, and can it be switched between 12VDC and 24VDC?
A: The TEMPOA2X provides selectable output at 12VDC/2.5A or 24VDC/1.25A, delivering up to 30W total. The voltage selection is made during installation based on your peripheral device requirements.
Q: Does the TEMPOA2X support battery backup?
A: Yes. The enclosure accommodates sealed lead acid or gel-type batteries (not included) to maintain operation during AC power loss. Battery capacity determines backup runtime and must be sized separately.
Q: How many doors can the TEMPOA2X monitor?
A: The TEMPOA2X supports two door sensor inputs, two strobe trigger inputs, and two panic trigger inputs — it is designed for two-door occupancy alert configurations.
Q: What are the enclosure dimensions and weight?
A: The steel enclosure measures 8.5" x 7.5" x 3.875" and weighs 4.85 lb. Shipping weight is 5.45 lb in a 13" x 10" x 7" carton.
Q: What input power does the TEMPOA2X require?
A: The unit requires 115VAC at 60Hz, drawing 0.5A. A standard 15A commercial branch circuit is sufficient, and multiple units can share a single circuit.
Q: What is the operating temperature range?
A: The TEMPOA2X is rated for 0°C to 49°C (32°F to 120°F) operating temperature and up to 85% relative humidity (±5%), suitable for standard indoor commercial environments.
The TEMPOA2X is the unit I reach for when a client needs a code-compliant occupancy alert at a two-door entrance and doesn't want to touch their main access control infrastructure. The selectable 12/24VDC output at 30W handles most strobe and sensor loads without a supplemental power distribution block — that's one fewer termination point in the enclosure and a cleaner install overall.
Technical Highlights:
- 30W at 12VDC/2.5A or 24VDC/1.25A: Enough headroom to drive two strobes, two door contacts, and panic hardware simultaneously without approaching the output ceiling — leaves margin for cable run resistance on longer pulls.
- 2 Switched + 4 Auxiliary Outputs: The switched outputs cut on alarm events while the four auxiliary rails stay live — important when you have sensors that would lose state if power-cycled during an alert condition.
- 0.5A at 115VAC Input: Half an amp per unit means a single 15A circuit can support a cluster of TEMPOA2X controllers in a multi-entrance retail or healthcare facility without a panel upgrade.
Deployment Considerations:
- Battery selection matters: sealed lead acid and gel cell have different charge curve requirements. Verify your chosen charger profile matches the battery chemistry you stock — mixing types shortens battery life and can cause nuisance low-battery alerts.
- The TEMPOA2X tops out at two door inputs. If your client later expands to a three- or four-door vestibule, plan for a second unit from the start rather than retrofitting — the enclosure does not support input expansion modules.
This unit fits best in single-entry commercial lobbies, healthcare waiting room vestibules, and retail compliance installs where two-door monitoring covers the full perimeter and the integrator needs regulated DC power on the same board — no separate power supply, no relay panel, one enclosure to mount and commission.
