Acme’s gas detection systems offer complete ventilation control and personnel protection for enclosed park-ing garages, truck loading docks, bus terminals, vehicle maintenance facilities, plane hangars, warehouses,offices, theatres and variable occupancy spaces.

01-01E-XR CEN Series

Carbon monoxide (CO) is an odorless, colorless gas that is fatal athigh concentrations and toxic over long periods of exposure. It is a by-product of the combustion of various fuels including gasoline, natural gas and propane, among others. To maintain a healthy environment in an enclosed vehicular facility, install CO detectors to start the exhaust fans and open fresh air dampers when the CO concentration rises to prescribed levels, normally 25 or 35 PPM based on local building codes. By using demand-based ventilation control you can save up to 70% of the energy costs when compared to running the fans full time, especially in hot or cold climates where heating or cooling is an added expense.Acme CO sensors use a robust PVC enclosure measuring 6" tall, 6"wide and 4" deep (152mm X 152mm X 101mm). Detectors are anchored to the wall using four mounting brackets and there are no controls accessible on the front of the unit, discouraging tampering. Indicating lights are provided for power on, one to four relay levels, a general alarm level and a sensor fault indicator. An LED bar graph provides an indication of the CO level over the 10-200 PPM typical range of the sensor.The E Series CO detector line can be equipped with one to fouroutput relays for fan control as well as a 4-20 mA signal for proportional control. The detectors can also be fitted with our RS- 485 communication card for connection to our CEL Series control panels. E Series units can have the number of output relays increased and communication features added later via a factory upgrade, so the investment is protected even if needs change over time. The CEN Series gas detection and control panel uses pneumatic sampling to bring gas from each sensing location back to the central panel. The advantage of pneumatic sampling systems is the ability to filter the air stream at both the sensing location and at the panel to remove suspended particulate and other solid contaminants. The filtration process keeps the sensors clean and extends their lifespan, improving performance and saving money for the building operator. Since one sensor for each gas can be shared among multiple sampling locations, lower servicing costs result since fewer sensors are replaced at service intervals when compared with purely electronic gas detection systems.The CEN Series panels use the same electronics as our CEL multipointpanels, so control technicians will be able to work on both types of panels without retraining. The CEN Series offers the same zoning capability, proportional and relay outputs for ventilation control, remote alarm indication and an RS-232 connection for reporting to a building automation system.The front panel includes LEDs for each detection point, indicating ifthe location has gas present at the low or high preset levels or if an alarm indication exists. Our four-line LCD display indicates the gas being sampled at each location, its concentration in PPM and if a ventilation or alarm level exists.The CEN Series is an ideal choice for dirty environments and forretrofitting older garages and facilities that my have pneumatic tubing in place, making conversion to a modern sampling system the economical choice

Technical features: 2 ) of clear open space. Practical considerations suchas an irregularly shaped space, the intrusion of divisions for elevators and stairs and ramping may require the installation of additional sensors. CO sensors should be located at breathing height between 4-6 feet off the floor (1.2m-1.8m). Sensors for Diesel fumes (NO 2 ), hydrogen, methane and am-monia should be located near the ceiling. Please consult with Acme’s tech- nical personnel who will assist you with sensor layout and recommend the proper height for the installation of the sensor types selected.
