Access Control and Building Systems
Door access, visitor communication and telephony designed around how people actually move through the building.

Reference system
Symptoms
When this matters
If any of these describe your environment, this is the conversation to have.
- 01Access credentials are still shared or handed out informally, with no audit trail.
- 02Visitor management relies on a paper register at reception.
- 03Intercom or gate systems were installed without any integration to CCTV.
- 04Extension and trunk changes require calling a vendor for every small update.
- 05Nobody currently administers who has access to which door.
Scope
What KINNEX delivers
Access control and building communication systems are only useful if they fit how people actually move through a site. KINNEX designs the credential model, entry flow and telephony together, then hands over clear administration so the system stays usable after installation.
- Door access, biometric or credential systems, controllers, locks and power design.
- VDP, intercom, gate and visitor communication systems.
- IP or hybrid PBX, extensions, trunks and related network requirements.
- Integration boundaries with CCTV, networks and client systems.
- Testing, user enrolment, administration handover and maintenance.

Any make, any model, from the manufacturer, distribution or registered importers. GST-compliant invoicing, warranty and returns handled for you.
- 03
Deliver
KINNEX engineers do the work we do every day. Where a job needs a specialist, we bring in the right expert team as a sub-order under your single contract.
- 04
Own
One scope, one SOP, one SLA and one point of accountability, whoever is on site.
Standards and terms
Standards we design to, and the terms you will hear
Specifications are written against recognised standards. Here is the vocabulary, in plain language.
- OSDP (SIA Open Supervised Device Protocol)
- ISO/IEC 14443 and ISO/IEC 15693 (contactless cards)
- EN 60839 (alarm and electronic security systems)
- EN 50131 (intruder alarm systems)
- EN 54 (fire detection and alarm systems)
- IEC 60849 and EN 54-16 (voice alarm)
- NFPA 72 (fire alarm and signalling)
- National Building Code of India (fire and life safety)
- IEC 62676 (video systems, for integration)
- BACnet and Modbus (building integration)
- KNX and DALI (lighting and building control)
- ISO/IEC 27001 aligned operating practices
- Access level
- A named set of doors and times a person is allowed to use, assigned to groups instead of individuals.
- Anti-passback
- A rule that stops one credential being used twice to enter, so a card cannot be passed back to someone else.
- Mantrap / airlock
- Two interlocked doors that never open together, used for high-security entry such as data centres.
- OSDP
- A modern, encrypted protocol between readers and controllers, replacing the older Wiegand wiring.
- Wiegand
- An older, unencrypted reader wiring standard still found in many existing installations.
- MIFARE / DESFire / SEOS
- Families of smart-card technology. Newer ones use stronger encryption than basic proximity cards.
- Fail-safe vs fail-secure
- A fail-safe lock opens when power fails, for life safety. A fail-secure lock stays locked, for security.
- VDP
- Video door phone: a doorbell panel with camera and a screen or app inside the home.
- Addressable fire alarm
- A system where each detector has its own address, so the panel shows exactly which device triggered.
- Voice evacuation
- A fire-alarm sound system that gives spoken instructions instead of only sounders.
- BMS
- Building management system: the software that monitors and controls HVAC, lighting, energy and other building plant.
- Muster
- An emergency roll-call. The access system lists who is on site and who has checked in at the assembly point.
- SOP and SLA
- The documented procedures for operating and maintaining the systems, and the response targets agreed for them.

Questions
Frequently asked questions
Yes, within a defined integration boundary — an access event such as a forced door can be linked to a camera event, without merging the two systems into one point of failure.
Card, biometric or mobile-credential systems are all viable depending on your security requirement and user volume; the right fit is assessed during design.
Through VDP or intercom systems that let reception or security verify a visitor before granting entry, with optional recording where required.
Both routes are viable — a hybrid PBX can bridge existing lines while extensions and trunks move to IP over time.
Administration can be handed over to your team with training, or retained under a support agreement — this is agreed before deployment, not decided afterwards.
