Acme Engineering Products CEW(LS) Series Gas Sensors

The ACME Wireless MultiSet series is a microprocessor-based multi-point multi-gas wireless detection and control system that can be used with wireless CO and NO2 gas sensors. Communication between the control panel and the remote GasPost sensor transmitter is accomplished via a 900 MHz or 2.4 GHz wireless network operating within the 1500-2000 ft. (indoor) range. The versatility of the multigas wireless detection and control system allows users to customize system parameters (switch level setpoints,time delays,hysteresis,scan rate,sensor type and range,etc.). Menu-driven options are displayed in plain English for easy on-site programming. The LCD display provides a continuous digital readout of each sensor transmitter gas concentration,as well as level status (low,high and alarm),battery voltage and elapsed time in minutes since the last transmission,MultiSet control panel support Up to 256 channels,each of which is processed independently,controls a fan zone. In this configuration,each channel has a set of relay outputs for low,high and alarm levels and/or a 4-20 mA signal proportional to gas concentration. In a more practical application,channels are divided into groups that collectively serve different fan zones. In the latter configuration,each group (zone) has a set of relay output contacts and/or a 4-20mA signal proportional to the group's needs. CEW-LS also features an optional BACnet IP interface. This option provides unmatched read/write options. This option provides full visibility of all network points and allows users to wirelessly operate peripherals such as fans using override commands.
