B14 Gas Alarm Receiver

The B14 Gas Alarm Unit is a module that provide local alarm, display and signal re-transmission for a gas detection system.


The B14 Gas Alarm Module Receivers are designed to accept input from either two, there or four wire 4-20mA transmitters that can be located up to 10,000 feet away from the receiver.  The Module provides local alarm, display, and single re-transmission functions for ANY gas detection system.  This system is perfect when you need to monitor gas from a few different rooms but want to have a remote location that displays those gas levels.  The B14 can be hooked up to a wide range of Gas Monitors (even if they do or don't have displays on the actual device themselves) and display the gas concentration on the B14 unit.  It is compatible with 38 different gases.

B14 with a variety of sensor types that can be connected up to 10,000 feet away from the B14.

Features of the B14:

     -LED Display: Gas concentrations are shown on the display in PPM, PPB, percent, or percent LEL.  This range is determined by you at the time of ordering.

     -Three Alarm Setpoints: Each module provides separate caution, warning, and alarm setpoints with LED bar indicators of each alarm point.  LED flash on initial alarm condition, and change to steady when the alarm is indicated.

     -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 non-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 singal or if the 4-20mA input drops below a specific value.

     -Remote reset Input: Isolate input contacts 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.

     -Signal Retransmissions: A 4-20mA output is provided from each module, optically isolated from the input signal to avoid ground fault problems.

     -DC 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). Customer provided 12-28 VDC supplies may also be used.


B14 How to Order - Please Contact Us to order, as these units are very customizable!

Alarm Measurement Range - We will need you to provide the gases and range in which you want displayed.  Each module is custom set, so you can have a variety of gases and ranges. 

Enclosure - The B14 comes in a variety of size enclosures based on the number of receivers and power supplies that you need.  The enclosure is a NEMA 4X material and uses standard 35mm DIN rail for mounting modules in the enclosure.

     -Single Module - Houses only a single receiver module for use in DC power application where the use provides power to the system.

     -Two Module - Houses two receivers (user supplies DC power) OR one receiver and one power supply (AC power).

     -Three Module - Houses three receivers (user supplies DC power) OR two receivers and one power supply (AC power).

     -Six Module - Houses six receivers (user supplies DC power) OR 4 receivers and two power supplies (AC power).

     -Nine Module - Houses nine receivers (user supplies DC power) OR eight receivers and one 65 Watt Power supply.


Extra/Accessories that take up a spot on the Enclosure:

     - Receiver Alarm Module- Power Supply (00-0055) - can power 3 alarm modules
     - Power Supply (28-0004) - can be used for up to 12 alarm modules
