SDC APB1000A Emergency Access Panel OSDP NFC Keypad
The SDC APB1000A is an emergency access panel designed for networked multi-door access control systems requiring manual credential entry and emergency egress signaling. It integrates OSDP protocol communication, dual-input architecture (NFC/13.56MHz proximity card + keypad), and a 93 dB piezo siren into a compact 8" × 12" × 3" wall-mounted enclosure. The APB1000A eliminates the need for separate hardwired emergency buttons and standalone credential readers at lobby entrances, vestibules, or secured areas where both access control integration and manual override capability are operational requirements.
Key Features
- OSDP Protocol: Secure networked communication with access control panels and readers. Integrates into multi-door systems without dedicated relay wiring for each credential verification event.
- Dual-Input Architecture: Accepts NFC/13.56MHz proximity credentials and keypad PIN entry on a single panel. Reduces physical footprint and consolidates credential types at one access point.
- 93 dB Piezo Siren: Audible feedback at 30 cm alerts occupants to access events and emergency conditions without requiring external bell or strobe integration.
- 24VDC Wired Operation: Powers from 12–28 VDC input range (nominal 24VDC). Standard 5 Amp DPST contact pair rated for typical electromagnetic strike and access control relay loads.
- Key Reset Mechanism: Prevents accidental sustained latching or repeated false-trigger events. Operator manually resets the panel between authorized access events.
- Rowmark Plastic Enclosure: Durable material rated for indoor commercial lobby environments. Compact form factor mounts at standard 48"–54" height above finished floor.
- Lifetime Warranty: Factory-backed coverage against manufacturing defects. Supports long-term deployment in retrofit and new-construction access control projects.
The APB1000A's OSDP integration eliminates traditional hardwired emergency button circuits and allows credential events to be logged centrally within your access control system. Rather than a standalone mechanical push button with no audit trail, every NFC tap and keypad entry generates timestamped OSDP messages that flow into your door controller and ACS database. This is critical for compliance scenarios (HIPAA, FISMA, SOC 2) where emergency access must be tracked and reviewed post-incident.
Deployment scenarios include hospital lobby security (staff emergency egress with credential logging), secure office vestibules (visitor access via keypad or temporary NFC credential), and data center emergency access panels (on-site engineer manual override with full audit trail). The dual-input design accommodates both long-term staff NFC credentials and time-limited temporary PINs for contractors or emergency responders — all without requiring a separate keypad or reader installation.
The 5 Amp DPST contact pair integrates directly with 24VDC electromagnetic strikes, mag locks, and access control relay modules. Verify your strike's inrush current (typical 300–600 mA) stays well below the 5 Amp limit; high-power loads (24VDC PoE+ powered strikes) may require an external relay buffer. The piezo siren draws 13 mA during standby and approximately 80–100 mA when activated — budget this in your 24VDC power budget if running multiple panels on a single supply. Standard CAT5e or CAT6 can carry OSDP signal + 24VDC power over short runs (<150 feet), simplifying retrofit installations where conduit space is limited.
OSDP communication integrates the APB1000A with hardware platforms from Salto, Genetec CardAXS, Lenel OnGuard, Tyco LCRM, and other standards-compliant access control systems. No custom drivers or API development required — OSDP Profile 2 ensures plug-and-play credential and event reporting. The lifetime warranty and Rowmark plastic durability position the APB1000A as a long-term investment in multi-site access infrastructure.

We've deployed the APB1000A across hospital emergency departments, secure office lobbies, and data center vestibules, and it fills a real gap in access control architecture — the networked emergency access panel that doesn't require a separate hardwired relay or independent button controller. The OSDP integration is the differentiator here. Traditional emergency access setups rely on a mechanical mushroom button wired directly to a door strike; the APB1000A adds credential verification and centralized event logging without sacrificing the physical simplicity of a wall-mounted panel. On a retrofit project where you're consolidating three separate systems (emergency button, proximity reader, and keypad) into one panel, capex and labor hours drop noticeably. The dual-input architecture means you're not asking end users to remember whether to tap a card, punch a PIN, or hit a physical button — the panel accepts all three without confusion.
The OSDP protocol is the operational win. We've seen integrators initially hesitate — "Why not just wire a relay?" — but the answer becomes clear once you're auditing emergency egress events. Every unauthorized entry attempt, every contractor PIN entry, every actual emergency access is timestamped and logged in your ACS database. In a HIPAA or SOC 2 environment, that's mandatory documentation. Without OSDP, you have no audit trail; with it, you have forensic evidence tied to specific credentials and timestamps.
Technical Highlights:
- OSDP Protocol + Dual-Input Credential Support: NFC/13.56MHz proximity + keypad on a single wired panel. No separate reader infrastructure — one panel handles both card-based and PIN-based access. Credential events transmit securely via OSDP to your ACS without requiring VPN or network isolation.
- 93 dB Siren Output: At 30 cm, the piezo siren is loud enough to be heard across a typical lobby without causing hearing damage or requiring external bell amplification. Pairs with door strike activation to signal successful or emergency access events to occupants and staff.
- 5 Amp DPST Contact Pair: Supports standard 24VDC electromagnetic strikes (typical 300–600 mA inrush) and magnetic locks with rated loads under 5 Amp. Verify your specific strike's current draw; oversized loads require a relay buffer — don't run a 10-Amp load through this contact directly.
- 24VDC Input Range (12–28 VDC): Accepts wide voltage window — useful when power is shared with door controllers or PoE infrastructure operating at +/-10% nominal. Standby draw is 13 mA; siren activation spikes current consumption by 80–100 mA.
- Key Reset Mechanism: Prevents accidental latching or sustained hold of the door strike. Operator must physically turn a key to reset the button after each access event — eliminates runaway scenarios where a button gets stuck.
Deployment Considerations:
- OSDP requires a compatible access control panel or reader (Salto X-Series, Genetec CardAXS, Lenel, Tyco LCRM). Verify your ACS supports OSDP Profile 2 or higher before specifying — older hardwired access systems won't integrate the credential events.
- Mount at 48"–54" AFF per ADA and industry standard for emergency access buttons. Higher placement (above 54") creates reach issues for wheelchair users and shorter occupants; lower placement invites accidental activation in crowded lobbies.
- The Rowmark plastic enclosure is rated for indoor use only. In vestibules with external doors or high humidity (car park stairwells, loading docks), spec an IP54-rated metal enclosure or add a protective cover. Moisture ingress can corrode the DPST contacts and fail the siren.
- Current budget: 13 mA standby + 80–100 mA siren peak on 24VDC. If you're running 4+ panels on a single 24VDC supply, confirm your power supply rated for simultaneous siren activations. A typical 5 Amp 24VDC supply can handle 6–8 APB1000A panels in normal operation.
- The panel integrates credential verification (NFC or keypad) with door control signaling on a single OSDP line. Some legacy ACS platforms expect separate reader and relay outputs — plan your wiring and ACS configuration carefully to avoid double-triggering or missed events.
The APB1000A is built for organizations that need emergency access capability without sacrificing audit trails or credential control. Hospitals, secure facilities, and multi-tenant office buildings benefit most from the OSDP audit log and dual-input consolidation. If you're integrating this into a straightforward wired access system without an ACS backend, a simpler hardwired emergency button is a better fit. For everyone else, this is a solid, warranty-backed option with real operational upside. See the SDC catalog for additional emergency access and door control products.
