Marketing Strategy: Fixed Gas Detection Systems
Fixed gas detectors contribute to about 80% to our total revenues. Our biggest markets are enclosed parking facilities for monitoring CO and NO2 gases, and in some cases, combustibles (natural gas or propane powered vehicles).
A typical average sized parking garage may require from a few dozen to several hundred units of toxic (and combustible) gas detectors, depending on how big the parking area is and the number of parking levels. Each gas detector can monitor up to 700 square metres of parking area. The strategy in promoting fixed gas detectors is to call on HVAC/R engineers and consultants. These are the people who make the engineering designs and estimates for building projects including parking garages. We would normally conduct product presentations to their engineers to educate them on our products and the solutions we can provide for their projects. We can support you by conducting a webinar for them if you can make the arrangements by gathering all engineers involved at a pre-arranged time and date. The webinar will only take about an hour. Our goal in these presentations is to get our product specifications into their project specifications. This strategy has been proven to be very effective as evidenced by the many building projects showing our specs under “gas detection” and mechanical subcontractors calling on us for a quotation because our specs are shown in their bid documents as
“Approved manufacturer: Critical Environment Technologies Canada Inc.”.
In most cases, the building owners will purchase whatever the consultants recommend. If the consultant recommends CET gas detectors and controllers, the building owners will not deviate from it. Even if it goes thru a bidding process, the bid specs will be based on our system specifications narrowing our competitors’ chances of winning the bid. This is how we approach this market. This is also the reason why we have “Sample Engineering Specs” available in our website which we provide to the consultants so there will be no need for them to spend time thinking about writing details of the specs. All they need to do is copy and paste our sample specs. Attached is an engineering specification sample on “Gas Detection System for Carbon Monoxide (CO) and Nitrogen Dioxide (NO2) for Parking Garages”. We therefore encourage you to spend time and resources in promoting our fixed gas detection systems in this manner since enclosed parking garage is our biggest market and it will guarantee big returns in your investments. We have engineering specification samples on almost evey gas detection application which you can download from our website under “Support” and then click on “Technical Library”. You can also send me an email and I will gladly send it to you. To give you another example, also attached is an engineering specification sample on “Refrigerant Leak Detection System for Mechanical Rooms”. We hope to hear back from you regards this suggestion and let us know what support you need from us.
ENGINEERING SPECIFICATION SAMPLE
FCS-M with CGAS-D-CO-NO2
Gas Detection System for Carbon Monoxide (CO) and Nitrogen Dioxide (NO2) for Parking Garages
Provide a wall mount, field programmable control panel with back-lit, LCD digital display, LED alarm indication, and door mounted 90 dB audible alarm with silence / acknowledge switch. There shall be an LCD display of gas type, concentration measured, and alarm status. System controller shall be capable of supporting up to 128 digital transmitters on an RS485 Modbus network. The controller shall have 4 on board relays and shall support analog output modules (four only 4 – 20 mA outputs per module) and relay output modules (four or eight 5 A SPDT relays per module) if required. The system RS485 Modbus network wiring shall be 4-wire (2 low voltage power wires and a shielded twisted pair for the communication bus). The controller shall be CSA / UL / CE / FCC / IP tested and certified, and powered by 90 to 240 VAC, 47 to 63 Hz. The controller should be installed in a dry area if it does not have the optional key lock. If it is to be installed in an area that requires a water/dust tight enclosure the key lock version must be requested.
If communication to a DDC/BMS is required, the FCS comes standard with Modbus output Model FCS-M and optional BACnet output Model FCS-B communication protocols.
Provide remote mount digital sensor transmitters with dual sensor capability for Carbon Monoxide (CO) from gas engine exhaust, with an electrochemical sensor for CO with a detection range of 0 – 200 ppm and Nitrogen Dioxide (NO2) from diesel engine exhaust, with an electrochemical sensor for NO2 with a detection range of 0 – 10 ppm. The sensor transmitter shall be housed in a rugged, water/dust tight, wall mount, polycarbonate junction box with a secured, hinged door. The remote mount sensor transmitter shall operate on power supplied by the control panel, and shall provide a Modbus digital output signal to the control panel. Model CGAS-D-CO-NO2
The electrochemical CO and NO2 gas sensors shall be capable of meeting government Occupational Health and Safety measurement standards for workplace exposure to toxic gases and vapours. Supply one sensor / transmitter for every 5000 to 7000 sq. ft. of area to be monitored. Install the sensor transmitters at 4’ to 6’ from the floor (breathing zone).
Optionally, provide remote mount audible, visual (strobe/siren) alarm to be mounted at higher elevations, activated upon any high alarm condition to alert of gas build up beyond high alarm concentration. Model RSH-24V
System operation shall be as follows: System relays are normally energized in non-gas-alarm state so they act in fail-safe operation. Upon detection of 25 ppm CO in air or 0.7 ppm NO2, the system shall illuminate the Low alarm LED, the Low alarm relays (ventilation) will be activated immediately. The system shall keep the ventilation running for a minimum of 10 minutes to avoid short-cycling.
Upon detection of 100 ppm CO in air or 1.5 ppm NO2, the system shall illuminate the High alarm LED, the High alarm relays and audible alarm will be activated. The system shall keep the High relays active for a minimum of 10 minutes.
Audible alarm can be silenced from the front panel push button.
The contractor shall provide all wiring, conduit and interconnection required for a successful installation.

Install the R410A sensor 12” to 24” from the floor (refrigerants are heavier than air) in an area where refrigerant leaks are most likely to occur.
System operation shall be as follows: Upon detection of 250 ppm R134A the system shall illuminate the Low alarm LED and top mounted strobe light on the FCS-4, activate any remote alarms if the system indicates a leak above the low alarm threshold and the Low alarm relay controlling the exhaust fan starter.
