The ACME CEL-LS Series is a microprocessor-based multipoint multigas detection and control system designed for use with various ACME gas sensors, including toxic, combustible, refrigerant, and oxygen sensors. It supports up to 256 addressable remote sensor-transmitters and 96 remote relay modules, utilizing RS-485 communication technology for reliable data transmission. The system allows for customization of parameters such as ON-OFF setpoints, time delays, and scan rates through a user-friendly removable keyboard and LCD display. The LCD provides real-time digital readouts of gas concentrations and status indicators for low, high, and alarm levels. The CEL-LS Series is suitable for applications in enclosed spaces like garages, tunnels, and warehouses, where hazardous gas accumulation may occur. In its basic configuration, the CEL-LS Control Panel can manage multiple fan zones independently, with relay outputs and 4-20 mA signals proportional to gas concentrations. The system is designed for energy efficiency by enabling intermittent operation of ventilation equipment based on gas detection. The expected lifespan of the sensors varies, with electrochemical sensors lasting approximately 2 to 7 years depending on the gas type. The CEL-LS Series also offers optional features such as a BACnet IP interface for integration with building management systems.
The ACME MegaSet series is a microprocessor-based
The versatility of the multipoint multigas detection system allows the user to customize the system parameters (ON-OFF level setpoints, time delays, hysteresis, scan rate, sensor type, and range, etc.) via a removable keyboard and LCD screen. The menu-driven options appear in plain English for easy field programming. The LCD display provides a continuous digital read-out of gas concentrations for each sensor/transmitter, as well as levels status (LOW, HIGH & ALARM), the battery voltage, and the time elapsed in minutes since the last transmission.
In its most basic configuration, the Megaset multipoint multigas detection Control Panel supports up to 256 channels where each channel is treated independently controlling 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 the gas concentration. In a more practical application, the channels are divided into groups that collectively serve various fan zones. In the latter configuration, each group (zone) has a set of relay output contacts and/or 4-20mA signal proportional to the demand from that group.
The CEL-LS also has an optional BACnet IP interface. This option provides a read/write option that is unmatched. This option provides full visibility of all network points and allows users to operate peripheral devices, such as fans, by using the override commands from the Building Management System (BMS).
