How we use ASSA ABLOY
Aperio wireless lock platform: Aperio is ASSA ABLOY's battery-powered wireless lock cylinder platform operating on 2.4 GHz Zigbee/proprietary mesh. Aperio cylinders (Aperio E100 for standard Euro profile cylinders, Aperio P100 for mortise locks) fit standard European lock formats and communicate wirelessly to an Aperio hub (RS-485 or TCP/IP connected to access controller). The Aperio hub provides a dry contact output per door — normally open, closes on door open — which is wired to KNX binary input modules (ABB M2184.1, MDT BE-0800.01) for door status integration. KNX group address: GA 5/floor/door_number DPT 1.002 door_open = 1 → ETS6 triggers: alert notification, corridor light ON, HVAC zone switches to occupied mode. Battery life: up to 3 years on CR123A depending on access frequency. HID OSDP readers: ASSA ABLOY's HID brand manufactures OSDP (Open Supervised Device Protocol, v2.1.9 IEC 60839-11-5) readers — the modern replacement for Wiegand 26-bit. OSDP readers (HID RP40, Signo 20/40 series) communicate with the access controller over RS-485 at up to 115,200 baud with AES-128 encrypted bidirectional communication — unlike Wiegand (one-direction, unsupervised). OSDP supervision: controller detects reader tamper and offline conditions in real-time. KNX integration: access controller programmable output (relay or TTL digital) → KNX binary input → door status, access denied/granted events as KNX group address DPT 1.001 telegrams → ETS6 routes to building automation (lights, HVAC, visitor log display on Gira X1). VingCard hotel systems: VingCard (acquired by ASSA ABLOY in 2011) is the world's leading hotel room lock supplier, present in 45,000+ hotels globally. VingCard Essence and Allure locks use Mifare Classic/DESFire EV2 RFID keycards encoded by the property management system (PMS) via VingCard Visionline server. The VingCard room lock presence function: when a guest inserts their keycard, the door handle authorises entry AND the card switch contact closes — KNX binary input detects card presence → GA 10/room/0 DPT 1.002 presence = 1 → HVAC comfort mode, welcome lighting scene. KNX-PMS integration: VingCard Visionline server (PMS middleware) triggers check-in/check-out events → KNX group address commands via middleware. CLIQ remote key management: for high-security mechanical/electronic hybrid locks in infrastructure, data centres, and critical facilities: Abloy CLIQ system uses electronic key cylinders with a digital audit log — who opened which lock at what time. CLIQ Connect (Bluetooth 5.0 mobile key) allows keyless access via smartphone app. KNX integration at data centre level: CLIQ controller dry contact output → KNX binary input → server room door open event → KNX relay output → alert siren, HVAC emergency ventilation ON, CCTV recording trigger (via KNX-Milestone plugin).
ASSA ABLOY door status (Aperio dry contact, Wiegand relay, OSDP digital output) → KNX binary inputs → DPT 1.002 group addresses for presence detection, HVAC occupancy switching, lighting automation, and security alarm integration. VingCard card switch contact → KNX hotel room presence. No proprietary ASSA ABLOY KNX module required — standard dry contact integration covers all use cases.
Used in these project types
ASSA ABLOY products
Key components we install
Aperio E100 wireless cylinder
Battery-powered wireless lock cylinder for standard Euro profile locks. Operates on 2.4 GHz Zigbee/proprietary mesh, communicating wirelessly to the Aperio hub — no cable required to the lock cylinder itself. Fits standard European double-cylinder door locks. Aperio hub (RS-485 or TCP/IP) provides one dry contact relay output per door for KNX binary input integration. Battery life: up to 3 years on CR123A. Access decisions made by the connected access controller — the Aperio cylinder itself is a wireless interface. Suitable for office, commercial, and hotel back-of-house doors where cabling to every lock is impractical.
HID RP40 OSDP Bluetooth reader
Multi-technology card reader supporting OSDP v2 (IEC 60839-11-5) over RS-485 with AES-128 bidirectional encrypted communication. Replaces legacy Wiegand readers with supervised, tamper-detected connection to access controller. Supports Mifare DESFire EV2, Mifare Classic, HID iCLASS, and Seos cards. Bluetooth Low Energy (BLE) for mobile access via HID Mobile Access app. OSDP supervision: access controller detects reader tamper and cable cut within 1 second. IP65 outdoor rated. KNX integration via access controller relay output: access granted/denied events → KNX binary input → DPT 1.001 telegram → ETS6 building automation triggers.
VingCard Allure hotel lock
Hotel room door lock with Mifare DESFire EV2 RFID keycard reading, connected to VingCard Visionline PMS server. Card switch contact (closes when guest card inserted in room holder) wired to KNX binary input: card presence → DPT 1.002 = 1 → HVAC comfort mode and welcome lighting scene. PMS integration: guest check-in in Opera/Mews/Protel → Visionline encodes keycard with room number and validity period → desk agent issues card at front desk. Check-out: card expires, room switches to eco mode via KNX. Available in multiple finishes (brushed stainless, black, white) for hotel interior design specifications.
Abloy Protec2 Cliq smart padlock
Electronic/mechanical hybrid padlock combining Abloy disc detainer mechanical security (highest pick/drill resistance) with CLIQ electronic authentication. Electronic key contains a digital certificate — lock only opens if key's certificate is valid for that lock at that time. Audit log: every opening recorded in key memory (up to 100 events), downloaded to CLIQ management software via key programming station. KNX integration via CLIQ controller dry contact output: padlock open event → KNX binary input → DPT 1.002 alarm → relay output → alert, ventilation, CCTV trigger. Used in data centres, electrical switchrooms, and critical infrastructure.
HID Signo 40 multi-tech card reader
High-security multi-technology reader supporting OSDP v2 over RS-485 (AES-128), Bluetooth Low Energy, and NFC (ISO 14443/15693). Reads Mifare DESFire EV2/EV3, HID iCLASS SE, Seos, and legacy Mifare Classic cards. Mobile access via HID Origo and HID Mobile Access apps (iOS and Android). IP65, IK08 vandal-resistant. OSDP supervised connection: access controller detects reader tamper in real-time. Suitable for high-security entrance control where multiple credential types must be supported. KNX integration: controller relay output on access event → KNX binary input → group address write.
ASSA ABLOY FAQ
How does ASSA ABLOY Aperio integrate with KNX — is there a native KNX module?
No native KNX module exists for Aperio. Integration is via hardwired dry contact: the Aperio hub (which receives wireless status from Aperio cylinders) provides one dry contact relay output per door. This normally-open (NO) contact closes when the door is opened. Connect the NO contact to a KNX binary input module (ABB M2184.1 or MDT BE-0800.01) using a 2-core 0.5mm² cable. ETS6 programs the binary input: on contact closed (door open) → send DPT 1.002 = 1 (alarm) to KNX group address → trigger corridor light, alert notification, occupancy mode. This dry-contact approach is universal — works with any access control brand that provides relay outputs, not just ASSA ABLOY.
What is the difference between Wiegand and OSDP card readers for KNX integration?
Both integrate with KNX via the access controller's relay output — the reader type (Wiegand vs OSDP) doesn't change how KNX receives door status. The difference is in security and diagnostics: Wiegand 26-bit is one-directional (reader to controller only), unencrypted, and unsupervised (controller cannot detect if reader is removed or tampered). OSDP v2 (IEC 60839-11-5) is bidirectional, AES-128 encrypted, and supervised (controller detects reader tamper and cable cut within 1 second). For building automation integration, this doesn't matter — KNX receives the same dry contact signal regardless. For security auditing, OSDP provides superior access log integrity and tamper detection that can be surfaced via KNX alarm group addresses.
Can VingCard hotel room locks be integrated with KNX without a PMS system?
Yes — partial integration is possible without PMS. The VingCard room lock card switch contact (closes when guest card is inserted in the holder near the door) can be wired directly to a KNX binary input. This provides presence/absence detection for HVAC and lighting control without any PMS connection or VingCard server involvement. The card switch is a simple mechanical contact — it doesn't communicate with the VingCard system at all. PMS integration (check-in triggering KNX welcome scene, check-out triggering eco mode) requires the VingCard Visionline server and a middleware gateway. For basic hotel room automation, card switch + KNX binary input is sufficient and eliminates PMS integration complexity.
