Series B14 - Accurate, Reliable Alarm,
Display and Signal Retransmission for
Gas Detection Systems

The Series B14 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 ATI's Series A12 or B12 two wire toxic gas transmitter or Model B12-17 three wire transmitter combustible gas transmitter.

• LED Display - Gas concentrations are indicated in ppm, ppb, percent, or % LEL with the display range selectable by the user.
• Three Alarm Setpoints - Each module provides separate caution, warning and alarm setpoints with LED bar indicators of each point. LED indicators flash on initial alarm condition and change to steady on when the alarm is indicated.
• Signal Retransmission - A 4-20 mA output is provided from each module, optically isolated from the input signal to avoid ground fault problems.

• Three Relay Outputs - 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 on-latching operation.
• Separate Trouble Alarm - 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 it the 4-20 mA input drops below a specific value.
• Remote Reset Input - Isolated input contracts are provided to allow an unpowered switch input for acknowledgment of alarm conditions from a remote location or via telemetry equipment.
• Internal Transmitter Power - Modules provide a 24 VDC power supply to operate either 2 or 3 wire transmitters.
• 12 VDC Powered - B14 modules are powered from a 12 VDC power supply available as an option. Up to 3 modules can be powered from one power supply (or 2 if battery backup is used).
