Multipoint Scanning Alarm System

Transcription

1 Multipoint Scanning Alarm System 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 l4 Scan Alarm) Receiver provides a versatile central monitor that can be configured to meet most multipoint gas detection applications. Features Monitors up to 16 analog 4-20 ma inputs from remote transmitters. Provides 24 VD power for up to 16 looppowered toxic gas transmitters or 12 3-wire combustible gas transmitters. Two line alphanumeric LD provides sequential display of each channel and the alarm status for that channel. Display locks on any channel that goes into alarm. Remote alarm reset input. Two programmable alarm setpoints 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. Battery backup module available to operate the system for up to 30 minutes with the maximum number of combustible gas transmitter inputs (worst case). 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. Standard NEMA 4X wall mount enclosure. Optional panel mount configuration.
