ELK Products ELK-965 28VDC Security Accessory Sensor
Overview
The ELK-965 is a 28VDC auxiliary component purpose-built for professional access control and alarm system integrations. This sensor accessory is designed to support auxiliary power distribution and signaling functions within networked security infrastructures where multi-door access control, alarm monitoring, or hybrid security deployments require reliable component-level support. The ELK-965 operates at 28VDC, a standard voltage in professional security installations, and integrates directly into ELK Products security system architectures.
Key Features
- 28VDC Operation: Runs on 28 volts DC — a voltage standard in access control and alarm system power supplies. This means you can share a single 28VDC bus across multiple ancillary devices (door strikes, readers, sensors) without needing separate supplies, reducing cabinet complexity and cost.
- Auxiliary Signaling Support: Designed to handle signaling and auxiliary distribution functions within multi-door access control environments. Sensor-based logic integration allows the ELK-965 to support decision trees and automation routines tied to door open/close, tamper detection, or alarm state transitions.
- Multi-Door Access Control Compatible: Suitable for integration into scaled deployments where auxiliary component support is critical — warehouse loading bays, multi-tenant office access, or campus perimeter gates. The component integrates into ELK system architectures without requiring custom firmware or bridge modules.
- Alarm Monitoring System Integration: Pairs with professional alarm monitoring panels to provide sensor input aggregation, allowing integrators to consolidate security signals (motion, door contact, pressure) into a single alarm event stream.
- Hybrid Security Deployment Ready: Bridges traditional alarm and access control logic with modern network-connected systems. The ELK-965 can be deployed in environments mixing legacy hardwired sensors with IP-based monitoring infrastructure, useful during phased security system upgrades.
- Professional Integrator Grade: Built to installer specifications — no graphical UI, minimal configuration overhead, and designed for permanent installation in security cabinets or control enclosures. Assumes familiarity with 28VDC power budgeting and relay logic.
Integration & Compatibility
The ELK-965 integrates into ELK Products security system deployments. It operates on 28VDC power supplied by a compatible ELK alarm panel or dedicated 28VDC power supply. Before ordering, confirm that your existing access control system or alarm panel is an ELK Products model with available 28VDC auxiliary outputs. Mixing the ELK-965 with non-ELK alarm panels or access control systems requires protocol translation (gateway) or may not be supported — verify compatibility with your system integrator or the equipment OEM before committing to deployment.
The component is suitable for indoor cabinet installation or NEMA-rated enclosures in warehouse or industrial environments. Standard security industry mounting hardware and DIN rail configuration apply. Wire all 28VDC power and signal connections using appropriate gauge cable for your amperage load — typical auxiliary devices draw 0.5–2A per circuit. Oversizing power budget is standard practice to avoid voltage drop across long cable runs.
When to Choose a Different Model
If you are deploying a pure IP-based access control or alarm system (no 28VDC auxiliary requirement), or if you need PoE-powered sensors with Ethernet connectivity, evaluate higher-level ELK Products models or third-party IP sensor platforms instead. The ELK-965 is not a networked device — it is a hardwired component intended for centralized 28VDC power distribution. If your integrator is advocating for full IP convergence and moving away from 28VDC infrastructure, this product is not the right fit.
Frequently Asked Questions
Q: What power supply do I need to run the ELK-965?
A: The ELK-965 requires a 28VDC power supply. If you already have an ELK alarm panel with 28VDC auxiliary outputs, those can often power the ELK-965 directly. For standalone installations or high-load scenarios (multiple auxiliary devices), you will need a dedicated 28VDC regulated power supply rated for the total amperage of all connected devices. Confirm total amperage with your integrator before ordering the supply.
Q: Can I use the ELK-965 with a non-ELK alarm panel?
A: The ELK-965 is designed for integration with ELK Products security system architectures. Compatibility with third-party alarm panels or access control systems is not guaranteed. Consult your system integrator or contact the equipment manufacturer to confirm before deploying in a mixed-brand environment.
Q: Is the ELK-965 suitable for outdoor installation?
A: The ELK-965 is not rated for direct outdoor exposure. It is designed for installation in security cabinets, control enclosures, or indoor NEMA-rated boxes. If you need outdoor auxiliary sensor capability, work with your integrator to select a weatherproof IP-rated alternative or mount the ELK-965 in a protected enclosure.
Q: What is the warranty on the ELK-965?
A: Warranty details are provided in the product datasheet. Contact your integrator or the distributor for specific coverage terms and any applicable extended warranty options.
Q: Can I daisy-chain multiple ELK-965 components on the same 28VDC bus?
A: Yes, multiple ELK-965 components can share a single 28VDC power supply, provided the total amperage of all devices does not exceed the power supply's rated output. Your integrator should calculate total load and verify power supply headroom before installation.
Q: What is the typical current draw of the ELK-965?
A: Refer to the product datasheet for precise current specifications. Typical auxiliary sensors draw between 0.5 A and 2 A depending on the function and connected relay loads. Your integrator will factor this into the 28VDC power budget.

The ELK-965 is a straightforward 28VDC auxiliary component for access control and alarm system integrations — not a network device, and that is exactly its strength. If you're working in a warehouse, office campus, or multi-tenant facility where the alarm panel is already handling 28VDC distribution to door strikes, readers, and sensors, the ELK-965 slots into that infrastructure without adding complexity or requiring new power feeds.
Technical Highlights:
- 28VDC Native Operation: Operates directly on the 28VDC auxiliary bus supplied by most professional ELK alarm panels. This means no separate 12VDC or PoE infrastructure — if your cabinet already has 28VDC, the ELK-965 draws power and integrates immediately.
- Hardwired Sensor Integration: Designed as an auxiliary component, not an IP endpoint. Sensor inputs feed directly into alarm panel logic, reducing latency and eliminating network dependency — critical in high-reliability access control or emergency alarm workflows where every millisecond counts.
- Multi-Function Auxiliary Role: Supports power distribution, signaling, and relay logic aggregation within a single component. Typical deployments pair the ELK-965 with door contact sensors, motion detectors, or tamper switches to centralize alarm signal processing.
Deployment Considerations:
- ELK Ecosystem Only: This is a closed-architecture component — it integrates cleanly with ELK Products alarm panels and access control systems, but does not have native ONVIF or third-party API support. If your long-term strategy is moving to IP-based security, plan a staged migration path rather than investing heavily in new 28VDC infrastructure.
- Power Budget Discipline Required: 28VDC auxiliary buses are finite. Multiple auxiliary devices (door strikes, electric latch retraction, supplemental sensors) add up quickly. Always model total amperage and spec your 28VDC power supply with 20% headroom — undersizing leads to voltage sag, missed sensor readings, and unreliable door control.
- Cabinet Installation Assumed: This component is not weatherproof. It is designed for mounting in a control cabinet or indoor NEMA enclosure. If you need outdoor auxiliary sensor capability, the ELK-965 is not the answer — escalate to an IP sensor or a weatherproof hardened enclosure around the device.
The ELK-965 is ideal for integrators managing existing ELK-based access control infrastructure or deploying multi-door systems in controlled environments (offices, warehouses, secure facilities) where centralized 28VDC distribution is already in place. It is not a path forward for pure IP convergence — if your client is moving away from hardwired 28VDC infrastructure, recommend a higher-level ELK networked component or a third-party IP platform instead.
