ACI Q5 B5 SERIES SMART GAS TRANSMITTER  | BACnet & MODBUS GAS DETECTORS 

The Q5/B5 Series offers highly versatile gas detection solutions housed in durable, NEMA 4X rated plastic enclosures. The Q5 Series primarily provides analog outputs (4-20 mA, 1-5 VDC, or 2-10 VDC) and supports the proprietary RS-485 Modbus RTU/OptoMux protocol. The B5 Series is specifically designed for integration with Building Automation Systems (BAS), utilizing the BACnet MS/TP protocol. Both models feature an internal clock, a backlit LCD display for real-time concentration monitoring, and three user-configurable SPDT relays for direct control of auxiliary equipment like fans or alarms. Field-replaceable, pre-calibrated sensor modules simplify maintenance and minimize system downtime.

PRODUCT USES:

• Parking Garages: Monitors Carbon Monoxide (CO) and Nitrogen Dioxide (NO2) to control ventilation fans.
• Mechanical & Boiler Rooms: Detects leaks of combustible gases or toxic combustion byproducts.
• Industrial Plants: Provides process monitoring and leak detection for hazardous gases like Ammonia (NH3), Chlorine (Cl2), and Hydrogen (H2).
• Refrigeration Plants: Monitors for refrigerant gas leaks to ensure facility safety.
• Warehouses & Maintenance Facilities: Ensures safe air quality in areas where gas-powered equipment is operated.
