Series B14 – Gas Detection System Receivers

ATI’s Series B14 Gas Alarm Module Receivers are compact electronic modules that provide local alarm, display, and signal retransmission functions for gas detection systems.


ATI’s Series B14 Gas Alarm Module Receivers are compact electronic modules that provide local alarm, display, and signal retransmission functions for gas detection systems. The modules are designed to accept input from either two, three, or four wire 4-20 mA transmitters located up to 10,000 feet from the receiver. They are ideally suited for use with any of ATi’s series A12, B12, C12, D12, or F12 gas transmitters.

B14 Alarm Receivers are DIN rail mounted modules that can be supplied in single or multiple unit enclosures. Gas concentrations are indicated directly in PPM, PPB, percent, or percent LEL with the display range selectable by the user. Each module provides separate caution, warning, and alarm setpoints with LED bar indicators of each alarm point. LED indicators flash on initial alarm condition and change to steady on when the alarm is indicated.

Modules contain individual alarm relays for each alarm setpoint. However, each relay can be assigned to any setpoint to allow multiple alarm functions at a single alarm point. Relays are configurable for either standard or fail-safe operation and for either latching or non-latching operation. A fourth LED alarm bar and relay are provided to indicate trouble conditions. The trouble alarm and relay will activate on loss of input signal or if the 4-20 mA input drops below a specific value.
