Hanwha NOA-E1PW4 Access Control and Power Integration Solution
The Hanwha NOA-E1PW4 is a factory-assembled access control and power distribution enclosure purpose-built for multi-door deployments requiring centralized power management and integrated door control. Unlike field-assembled solutions, this unit ships pre-wired with all terminal blocks and custom wire harnesses installed and tested, eliminating weeks of on-site conduit routing, relay configuration, and splicing. The NOA-E1PW4 supports up to four doors using a single 2-door Intelligent Controller (IC2) paired with a Reader Interface Panel (RI2MS), delivering coordinated access policy enforcement and supervised power distribution in a compact 18.0" H × 14.5" W × 4.625" D galvanized steel enclosure.
Key Features
- Pre-Wired 4-Door Control: Arrives fully assembled with integrated terminal blocks and custom wire harnesses. No field splicing, no improvised conduit bends, no custom harness fabrication on-site — you terminate your field wires into pre-labeled blocks. This eliminates the single largest source of commissioning delay and wiring defects in access control deployments.
- Dual-Voltage Power Supply (eFlow6NB): Outputs 6A at both 12VDC and 24VDC with intelligent charging supervision, eliminating the need to stock separate power supplies. If your deployment mixes 12V badge readers, 24V solenoid strikes, and auxiliary sensors, a single supply handles all voltage classes without external regulators or secondary power sources.
- 8-Output Power Distribution Module (PDS8CB): Each output delivers up to 2.5A with integrated PTC (Polymeric Positive Temperature Coefficient) protection — effectively a thermal circuit breaker per branch. If a reader or auxiliary device draws excessive current, that individual output shuts down without affecting the remaining seven outputs. This compartmentalization cuts field troubleshooting time considerably; a failed reader doesn't cascade to adjacent doors.
- 4-Relay Access Control Module (ACM4CB): Four independently protected relays rated 2.5A each, with per-output PTC protection. Handles electromagnetic door strikes, gate operators, and auxiliary loads. The per-relay protection means a stuck strike solenoid won't trip the entire relay bank — only that relay de-energizes.
- Flexible Voltage Regulation (VR6): Supports 5–12VDC output range on demand, accommodating legacy 5V keypad controllers and modern 12V reader equipment without external regulators. Reduces the number of separate power taps required in the enclosure.
- Supervised Backup Battery Support: Accommodates up to two 12VDC/7AH batteries (14AH total capacity) with integrated AC fail detection, battery presence monitoring, and FACP (Fire Alarm Control Panel) integration supervision. In healthcare, government, and critical infrastructure deployments, this ensures access remains functional during utility power loss — a life-safety requirement. The supervision outputs also integrate with your fire alarm panel to trigger alerts if the backup battery fails.
- Factory-Tested Assembly and Removable Backplane: Pre-wired and tested before shipment, reducing field commissioning time and wiring defect likelihood. The removable 16 AWG galvanized steel backplane simplifies future modifications if door or load configurations change, without requiring complete re-assembly.
- Preconfigured Conduit Entry: One 1.5" main knockout and nine dual knockouts (accommodating 3/4" and 1" conduit) pre-configured for typical field wiring entry. Eliminates improvised drilling and conduit adapter stacking that creates stress points in the field.
- Azure Cloud Integration: Purpose-built for cloud-native access management platforms, enabling centralized credential provisioning, real-time audit logging, and policy deployment without on-premises directory synchronization overhead.
- North American Compliance: UL294 and cUL s319-05 certification ensure the NOA-E1PW4 meets electronic safety and access control system standards required for commercial security contracts, insurance underwriting, and public-sector procurements.
- Lifetime Warranty on Power Components: Power supply, battery chargers, and integrated sub-assemblies carry a lifetime limited warranty, reflecting design confidence in always-on access environments where unexpected downtime directly impacts security and operational continuity.
Integration and Compatibility
The NOA-E1PW4 integrates with access control systems engineered for Azure cloud platforms. All terminal blocks are pre-labeled and support standard 18–14 AWG field wire termination. Conduit knockouts accommodate 1.5" and 3/4"–1" entry sizes typical of commercial wiring standards. The eFlow6NB power supply and ACM4CB relay module are compatible with legacy solenoid strikes rated 12–24VDC, reducing the need for hardware replacement in retrofit deployments. The backup battery input supports standard 12VDC lead-acid or AGM batteries; the FACP supervision output can be wired to a compatible fire alarm panel for integrated life-safety monitoring.
When to Choose a Different Model
If your deployment requires more than four doors, or if you need more than eight independent power outputs, consider a larger modular enclosure or access control panel family from the same manufacturer that supports daisy-chaining multiple controllers. If you require hardwired (non-cloud) access control with on-premises directory integration, consult your systems integrator about non-Azure variants in the Hanwha catalog. If backup battery runtime exceeding 14AH is mandatory for your life-safety requirements, you may need an external battery cabinet or UPS solution paired with the NOA-E1PW4.
Frequently Asked Questions
Q: Does the NOA-E1PW4 support legacy 12VDC door strikes without modification?
A: Yes. The eFlow6NB power supply outputs both 12VDC and 24VDC simultaneously. Strikes rated 12–24VDC can be connected directly to the appropriate PDS8CB output. No external conversion is required.
Q: What happens if a door strike draws more than 2.5A?
A: The PTC protection on that individual PDS8CB output will thermally shut down, isolating the faulted strike without affecting the other seven outputs or the relay bank. Once the overload clears and the PTC cools, the output automatically restores. This prevents cascading failures across your access system.
Q: Is the NOA-E1PW4 compliant with fire alarm integration requirements?
A: Yes. The enclosure includes FACP (Fire Alarm Control Panel) integration supervision outputs for AC fail, battery fail/presence detection. These can be wired to your building fire alarm panel to trigger alerts if utility power or backup battery fails — a requirement in commercial and healthcare deployments.
Q: Can I expand the NOA-E1PW4 to control more than four doors later?
A: The NOA-E1PW4 is limited to one IC2 controller (2-door-rated) plus one RI2MS reader interface, supporting up to four doors total. If you need more doors, consult your integrator about adding a second enclosure or upgrading to a larger modular panel family that supports multiple controllers in parallel.
Q: What is the expected battery runtime with two 7AH batteries?
A: With 14AH total capacity, runtime depends on the combined draw of your readers, strikes, and auxiliary loads. For a typical single-strike setup (2–3A continuous draw), expect 4–5 hours. Larger deployments with multiple strikes or higher-draw readers will see proportionally shorter runtime; consult the NOA-E1PW4 datasheet or your integrator for load-specific calculations.
Q: Does the NOA-E1PW4 ship ready to install, or does it require factory programming?
A: The enclosure ships fully wired and tested. Programming of the IC2 controller and credential provisioning occurs through the Azure cloud management platform or via the RI2MS reader interface panel, depending on your deployment architecture. No factory programming customization is required.

The NOA-E1PW4 solves a real problem: integrators and warehouse automation teams spend disproportionate time wiring, terminating, and configuring power distribution and relay logic in access control enclosures. This unit arrives pre-wired, tested, and ready for field termination — a meaningful time saver on multi-door deployments. The dual-voltage eFlow6NB supply and per-output PTC protection are the standout technical features that directly reduce field troubleshooting and failure cascade risk.
Technical Highlights:
- Per-Output PTC Protection (PDS8CB + ACM4CB): Each of the eight power outputs and four relay outputs includes integrated Polymeric Positive Temperature Coefficient protection. When any single output exceeds its 2.5A rating, only that branch thermally de-energizes; the remaining outputs continue to supply power. This compartmentalization is critical in security deployments where one failed reader or strike cannot cascade and take down the entire access control infrastructure.
- Dual-Voltage Simultaneous Output (eFlow6NB, 6A @ 12/24VDC): The power supply delivers full 6A capacity at both 12VDC and 24VDC concurrently. This eliminates the common retrofit scenario where you need to wire separate 12V and 24V terminals and daisy-chain secondary supplies. A single supply feeds both legacy 12V solenoids and modern 24V sensors in the same deployment.
- FACP Supervision Integration: The enclosure includes dedicated supervision outputs for AC fail, battery presence, and battery fault conditions. These integrate directly with Fire Alarm Control Panels, meeting life-safety code requirements in healthcare, data centers, and government facilities where access must remain functional during power loss and all parties must be immediately notified of battery failure.
Deployment Considerations:
- The four-door limit is a hard ceiling with this configuration. If your facility requires more than four doors, plan for a second enclosure or a modular panel family that supports controller stacking — factor this into your design phase, not commissioning.
- Battery runtime (14AH max) is conservative for high-draw deployments. A typical electromagnetic strike draws 600mA–1A continuously during access attempts. If you have multiple strikes or sustained access during an outage, calculate realistic draw first; don't assume four hours of autonomy without load analysis.
- The removable backplane is a genuine commissioning advantage, but it adds 0.75–1 inch to the overall enclosure depth when fully populated with wire. Plan for adequate wall cutout clearance during rough-in.
The NOA-E1PW4 is the right choice for warehouse automation facilities, mid-size office buildings, and healthcare campuses where you're adding four or fewer doors, mixing voltage classes, and need battery backup and fire alarm supervision without designing a custom power distribution panel. If you're doing a 12-door retrofit or require hardwired on-premises control, this isn't your model — tell your integrator upfront.
