IAC Hardware Capacity and Expansion
Overview
The IAC provides local I/O and supports various expansion methods to increase door and zone capacity both within the cabinet and across a site via the RS485 LAN.
Technical Details
On-board I/O
- 2 x Door lock relay outputs.
- Dedicated Lock Power input.
- 2 + 2 Wiegand Reader inputs.
- 1 RS485 LAN Reader port.
- DOTL warning relay outputs for each door.
- Monitoring inputs (Reed & Tongue) for each door.
- REX & REN inputs for each door.
UniBus Expansion
A maximum of 6 UniBus boards can be connected. Note: UniBus Zone Expanders are NOT supported on an IAC UniBus port.
- 2-Door Expander (996535PCB&K): Adds 2 Wiegand ports / 2 Door lock outputs. (Max 3 supported)
- UART Expander (996520PCB&K): Adds 2 UART ports. (Max 4 supported)
- 8 Relay Expander (996515PCB&K): Adds 8 relays. (Max 2 supported)
- Lift Interface (996540PCB&K): Adds 16 floors. (Max 6 supported)
RS485 LAN Sub-LAN Expansion
Supports up to 240 additional doors via LAN modules. Up to 99 modules of each type can be connected regardless of Smart Card level (though license limits apply to the number of entities “in use”).
- SLAM: 2-Door cached module. Supports up to 4 SIFER or 2 Wiegand readers.
- ILAM: 2-8 Door high-capacity module. Supports up to 16 SIFER or 8 Serial readers.
- Integriti Modules: 8-Zone LAN Expander, EliteX/PrismaX Terminals.
- Legacy Concept Modules: Many Concept Type 0, 1, and early Type 2 modules are compatible (check firmware limitations).
Configuration / Programming
- Addressing: LAN modules use DIPswitches 1-7 for addressing (1-99).
- Relay Mapping: UniBus Relays mapped to X01-X16 are general purpose; X17-X32 mimic IAC Door Lock and DOTL outputs.
