Details:
Many gas detection applications require multiple sensing locations to provide adequate area protection for plant personnel. Signals from a variety of field measurement sites are often transmitted to a central location where display and alarming functions are needed. ATI's Series C14 ScanAlarm Receiver provides a versatile central monitor that can be configured to meet most multipoint gas detection applications.
The C14 ScanAlarm monitors up to 16 analog 4-20 mA inputs from remote transmitters, and provides 24 VDC power for up to 16 loop-powered toxic gas transmitters or 12 3-wirecombustible gas transmitters.
The two line alphanumeric LCD provides sequential display of each channel and the alarm status for that channel. Display locks on any channel that goes into alarm.
Two programmable alarm setpoints are available for each analog input plus a trouble alarm for each channel. Six assignable SPDT alarm relays in standard configuration, with expansion for up to 36 total relay outputs. One output relay is factory set for global alarm and one is set for system failure.
Standard RS-232/485 serial interface allows all configurations to be set up by computer and alarm events to be automatically monitored by computer. Up to 32 separate monitors can be connected to a single RS-485 communication link.
