Integriti Security Controller (ISC)

Overview

The Integriti Security Controller (ISC) is an IP-based master controller for the Integriti modular hardware system. It serves as the central processing unit for security, access control, and automation logic, supporting extensive expansion via UniBus and RS485 LAN Sub-LAN.

Technical Details

    • Auxiliary Relays (AX1/AX2): 30V DC or 30V AC RMS, 1A max.
    • Watchdog Relay: 30V DC, 200mA max.
  • Siren Driver: 2.3A output, 4 Ohm minimum load impedance.
  • Over-Voltage Protection: Battery limits output to 16V DC. Epcos S07K14 Metal-Oxide Varistors on all power supply outputs.

UniBus Expansion Limits

The ISC supports a maximum of 6 UniBus boards total. Specific device limits include:

UniBus Board TypeMax Supported

T6BATTERYBattery ConnectionPolarized connector. Red wire to Battery (+), Black wire to Battery (−). 5A Fast Blow fuse (F1a, non-replaceable).

NOTE

The ISC has onboard power supply circuitry with direct screw/clamp terminals for AC/DC input and battery. Unlike LAN modules (SLAM, ILAM, IAC, 8-Zone Expander), it does not require a 10-pin power cable.

Configuration / Programming

  • Addressing: Managed via Integriti software.
  • Firmware: Upgradable via USB, LAN, or Software.
  • Memory: 32 Bit ARM with Real Time Clock, 64 MB RAM. Rev G+ (2018+) uses on-board flash memory for database and review log. Pre-Rev G controllers used Micro SD.
