Gas Detector Calibration: An Overlooked Revenue Opportunity for Fire Alarm Dealers

Jul 11, 2025 | Gas Detection

Many fire alarm contractors don’t realize it, but gas detector calibration is one of the most overlooked recurring revenue opportunities in the low-voltage industry. Gas detectors are just another initiating device—no different than a smoke detector or pull station—but because they involve a specialty gas, many dealers mistakenly hand the job off to HVAC companies.

The truth is, if you already install gas detectors, you should be calibrating them, too.

Gas detection calibration is simple, fast, and repeatable. Best of all, it creates built-in service and maintenance opportunities that add recurring revenue to every gas detection system you install.

Key Product Features

Here’s what Macurco offers to make calibration straightforward for dealers:

  • Calibration Kits (Cal-Kit 1–5) tailored to each Macurco model family

  • Each kit includes: calibration case, 2’ tubing, calibration hood, and 0.2LPM or 0.5LPM regulator

  • Sensors supported: CO, NO2, H2S, CO2, refrigerant gases, ammonia, and oxygen

  • Simple YouTube videos for calibration and sensor replacement walkthroughs

  • NIST-traceable calibration gases available separately

  • Tech support from Macurco’s in-house team for step-by-step assistance

Use Cases / Dealer Benefits

Macurco gas detectors are found in parking garages, boiler rooms, mechanical spaces, and anywhere gas buildup poses a threat. These applications demand reliable detection—and that means yearly (or more frequent) calibration.

For fire alarm dealers, this represents a golden opportunity:

  • Add RMR (Recurring Monthly Revenue): Calibration should be done at least once per year. That’s a built-in annual service visit you can charge for.

  • Own the Maintenance: Don’t lose out to HVAC firms. These are your devices—you installed them. Offer a full-service solution.

  • Simple Process: Calibration takes minutes with the right kit. There’s no reason to outsource.

  • Expand Your Value: Dealers who offer complete gas detection support are seen as more capable and professional.

  • Code & Compliance: Many local codes require regular calibration. Providing documentation ensures your customers stay compliant.

Technical Summary for Gas Detector Calibration Kits

Macurco’s 6 & 12 Series detectors are compatible with dedicated calibration kits:

Calibration Kit Gases Supported Compatible Models
Cal-Kit 1 CO (50–200PPM), O2, CANN series CM-6/12, GD-6/12, OX-6/12
Cal-Kit 2 NO2, H2S CX-6/12, CM-6/12, TX Series
Cal-Kit 3 Refrigerant Gases RD-6/12
Cal-Kit 4 CO2 CD Series
Cal-Kit 5 Ammonia TX-6/12-AM

Each kit includes everything needed to perform a calibration, aside from the gas canister itself. Macurco requires the use of NIST traceable gas to ensure measurement accuracy and compliance.

Calibration typically involves:

  • Zeroing the Detector: Using clean air or nitrogen to establish a baseline.

  • Applying Calibration Gas: Ensuring the sensor responds accurately.

  • Adjusting Settings: If needed, using the regulator and Macurco documentation.

  • Documenting Results: Essential for compliance and future maintenance logs.

Regular calibration keeps sensors from drifting, maintains compliance, and protects life and property.

Why Gas Detector Calibration Is a Missed Opportunity for Dealers

Unfortunately, many security and fire contractors assume gas detection is too specialized, leading them to leave money on the table. HVAC techs often pick up that slack—installing, calibrating, and maintaining sensors when dealers could easily be doing this themselves.

Macurco’s calibration kits make the process accessible for any trained technician. If you’re already selling or installing gas detectors, adding calibration service is low-effort, high-return, and strengthens your relationship with the end customer.
