Honeywell System 57 Gas Detection Control System: Comprehensive Overview

Example 3: Underground Parking Garage

• Scenario: A large shopping mall has a multi-level underground parking garage that accommodates hundreds of vehicles. Carbon monoxide (CO) from vehicle exhaust can accumulate to dangerous levels if not properly ventilated.

• System 57 Application: A Honeywell 57C-I-12 controller is located in the building’s maintenance room. Multiple low-cost Sensepoint XCD CO detectors are distributed evenly across each parking level, typically near exhaust points and in low-lying areas where CO can accumulate.

• Operation: During peak shopping hours, vehicle traffic is high, and CO levels begin to rise in one section of the garage. The CO detectors monitor the ambient air and send continuous readings to the 57C controller. When the CO concentration reaches a preset low-alarm setpoint (e.g., 35 ppm), the controller triggers relays to start the exhaust ventilation fans for that specific level or zone. As CO levels decrease below the setpoint, the fans can be set to slow down or turn off (with a suitable delay), optimizing energy efficiency. If CO levels were to reach a dangerous high-alarm setpoint (e.g., 100 ppm), additional alarms could be triggered to alert building management and the public address system could be used to guide people away from the affected area. The system also logs CO trends for maintenance planning.
