Kenwei Intercom

Overview

The Integriti Intercom Communications Task provides an interface between the Integriti system and the Kenwei Intercom system. It uses an Apartment entity structure where apartments can grant access to Call Locations, temporarily unlocking Doors and/or Lift Cars.

Currently the only intercom system supported by the Integriti Intercom Comms Task is the Kenwei Intercom system.

Prerequisites

• Integriti Controller with an available RS485 LAN UART port
• Kenwei Intercom system with Indoor Monitor and Outdoor Camera units
• RS485 LAN connection between Integriti and Kenwei distributors
• Licensing: Intercom Comms Task license

Step-by-Step

1. Configure the Intercom Comms Task

1. Open the Communications panel from the Administration tab of Integriti System Designer.
2. Click Add and select Intercom as the communication task type.
3. Configure the serial port settings:
   • Baud Rate: 9600
   • Data Bits: 8
   • Parity: N (None)
   • Stop Bits: 1
4. Assign a name to the comms task.

2. Set Up Apartments

1. In Integriti System Designer, navigate to the Apartments entity list.
2. Create an Apartment for each Kenwei Indoor Monitor unit.
3. Configure each Apartment with:
   • Intercom System Floor: Matches the Kenwei Distributor module’s DIP switch Floor setting.
   • Intercom System Unit: Matches the terminal location number on the Kenwei Distributor.
4. Example: If the Kenwei Distributor is set to Floor 17 and the Indoor Monitor is on terminal 3, set Floor = 17, Unit = 3 (Kenwei address = 1703).

3. Configure Call Locations

1. Open the Intercom Comms Task configuration.
2. Define up to 32 Call Locations, each representing a Kenwei Outdoor Camera unit.
3. For each Call Location, optionally associate:
   • A Door (unlocked when access is granted).
   • Up to 4 Lift Cars (unsecured when access is granted).

4. Kenwei Addressing Reference

Component	Kenwei Address	Integriti Mapping
Indoor Monitor	Floor × 100 + Terminal (e.g., 1703)	Apartment: Floor + Unit
Outdoor Camera	Terminal number (1-based)	Call Location
Standard Distributor	DIP switch = Floor number	—
Outdoor Camera Distributor	Special type	—

5. Physical Connection

1. Connect the Kenwei Intercom distributor’s RS485 LAN to a UART port on the Integriti Controller.
2. Ensure the port configuration matches the Comms Task settings (9600,N,8,1).
3. Kenwei distributors communicate via their own RS485 LAN and can be daisy-chained in series.

Verification

1. Start the Intercom Comms Task — verify status shows Running.
2. From a Kenwei Indoor Monitor, trigger an “unlock” command.
3. In Integriti GateKeeper, check that:
   • Review event is logged showing the unlock request.
   • The associated Door unlocks / Lift Cars are unsecured.
   • If no matching Apartment is found, only review is logged (no access granted).

Troubleshooting

Issue	Check
No review events from Intercom	Verify RS485 wiring between Integriti UART and Kenwei distributors; check baud rate (9600,N,8,1)
Unlock does not open door	Confirm the Apartment’s Floor and Unit match the Kenwei Indoor Monitor address exactly
Key fob/PIN at Outdoor Camera not working	By design: Key fob and PIN authentication at the Outdoor Camera is not supported through the Integriti interface. Install an IR reader head alongside the Kenwei Outdoor Camera unit as a workaround
Multiple units not responding	Check Kenwei distributor DIP switch settings and series connections

Limitations

• No key fob access via the Kenwei Outdoor Camera unit — only Indoor Monitor unlock commands are processed.
• No PIN access via the Kenwei Outdoor Camera unit.
• Only the Kenwei intercom system is currently supported by this comms task.
