The Acme Quadset Refrigerant Gas Monitor is designed to detect refrigerant leaks in enclosed areas. The Monitor utilizes a sophisticated NDIR sensor specific to any one of the commercially available refrigerants. It can monitor over a range of 0-1000ppm with a resolution threshold as low as 1ppm.
The Quadset can monitor up to four locations in one of two modes of operation, diffusion or sample-draw.
In the diffusion mode, up to four RF-IR-ST-24 Refrigerant Sensor/ Transmitters can be daisy-chained to the Monitor and transmit data on a RS-485 communication bus.
In the sample-draw mode, built-in diaphragm pumps continuously draw air samples from the four locations via tubing, the incoming samples are then diverted to a built-in sensor by means of a sequencer and solenoid valves.
The Quadset is easy to install and maintain. It has a 4-line backlit LCD for refrigerant gas readings and LED indicators for relay output status. The LCD is also used for programming the system parameters via a removable keypad.
Designed to act as a fixed in-situ safety monitor, the Quadset automatically operates the mechanical ventilation system of a facility upon detection of low levels of refrigerants, thereby protecting occupants, personnel and gas-sensitive goods and products.
The standard Monitor has a 3-stage relay output configuration and a malfunction relay. Options include 4-20mA analog output based on average or worst reading, a strobe light and/or a horn.
With the increased use of gas detection in maintenance and industrial facilities, the Quadset allows installers and users to meet code requirements in an economical fashion using commercial-grade gas detection equipment.
The Quadset contains all the well-known standard features of ACME’s gas detection line; a robust enclosure, the latest sensor technology and state of-the-art electronics. For more versatile gas options, please consult the ACME binder or website.
