Mircom INX-10A Intelligent Nac Expander/Power Supply Owner’s Manual

Mircom INX-10A Intelligent Nac Expander/Power Supply

Description

• Mircom’s INX-10A is an Intelligent NAC expander/ power supply that works with listed compatible Intelligent fire alarm control panels. Available in a 10 Amp configuration, the INX-10A can extend the power capabilities of existing notification appliance circuits as well as provide power for other ancillary devices. In addition, the INX-10A has the ability to operate with any UL/ULC Listed 24 VDC fire alarm control panel to provide Notification Appliance Circuit expansion.
• The INX-10A is equipped with five individual Class B (Style Y) or Class A (Style Z) output circuits that can be independently configured for NAC operation or auxiliary power. The INX-10A provides the option of configuring all five circuits as an output to provide general purpose power. In addition output circuits four and five can be configured to provide auxiliary power for four-wire detectors or door holders.
• Each output circuit is rated for 2.5 Amps. When configured for NAC operation the outputs can be set for Steady, Temporal Code, California Code or March Time. In addition the output circuits have field selectable built-in strobe and horn synchronization protocols to support Amseco, System Sensor, Wheelock and Gentex devices, eliminating the need for additional external synchronization modules.

• Compatible with any UL/ULC listed 24VDC conventional fire alarm control panel to provide Notification Appliance Circuit expansion

Modes of Operation

• Intelligent NAC Expander (INX) Modes
  The INX-10A features three modes of NAC Expander operation:

  • INX Mode with Internal Sync
  • INX Mode with External Sync
  • INX Mode with Redundant Input

• Input Mode with Internal Sync
  In this mode all signal and sync strobe rates are produced in the INX-10A.

• INX Mode with External Sync
  When one of the Sync Inputs is activated, the INX-10A outputs follow the signal pattern of the Sync Input. The NX-10A must be configured as a slave to operate in this mode.

• INX Mode with Redundant Input
  The system continuously monitors the SLC loop. If there is no activity for a notable time, an SLC trouble is generated. While the SLC trouble is active, if either of the Sync Inputs are activated then all NAC outputs follow.

• Power Supply Modes
  In addition to the NAC expander modes, some or all of the NAC outputs on the INX-10A can be configured for the following power supply modes of operation:

  • NAC Outputs as Power Supply Outputs
  • NAC Outputs for Door Release
  • NAC Outputs for 4-Wire Smoke Supply

• NAC Outputs as Power Supply Outputs
  This mode allows any NAC output to be configured as a power supply. The SLC and Sync inputs are ignored for the power supply outputs.

• NAC Outputs for Door Release
  This mode allows NAC circuits 4 and/or 5 to provide power for door holders.

• NAC Outputs for 4-Wire Smoke Supply
  This mode allows NAC circuits 4 and/or 5 to provide auxiliary power for 4-wire smoke detectors.
