  mounted audible alarm installed

The QCC Quad Channel Controller offers 4 channels for monitoring toxic, combustible and/or refrigerant gases with 
versatile control functionality for non-hazardous, non-explosion rated, commercial and light industrial applications. 
It is designed to accept inputs from up to four remote digital and/or analog transmitters using digital or 4-20 mA 
analog input.

The QCC is available in two models: the QCC-M with Modbus® RS-485 output or the QCC-B with BACnet® MS/TP 
output for communicating with a Building Automation System (BAS).

Standard features include, three configurable SPDT dry contact relays with field configurable time delays and trigger 
levels, an LCD display with LED indicators for channel alarm status, relay status and fault conditions, an extensive 
menu system with password protection, logic control, a USB port for firmware upgrades and a door mounted, loud 
audible alarm that is ideal for noisy environments.

Optional value added features include: an analog output module with two analog outputs and data logging, a manual 
shutoff switch (meets B52 code requirements), a top mounted strobe and a water tight, door mounted audible alarm.

The QCC can be connected to several remote devices such as any of the Remote Strobe & Horns, a QCC-RDM Remote 
Display Module and the LNK-AO Analog Output Peripheral device.
