Gas Concentration Alarm
A fixed gas monitor with local concentration display, staged alarms and remote control-system outputs.
- Continuous Concentration Display
- Multi-Level Alarm Relays
- Local Beacon and Sounder
- Remote BMS Interface
Product Introduction
The gas concentration alarm powers and reads a compatible fixed sensor, displays the measured value and drives configurable warning and alarm outputs. Relay contacts, analog signals or industrial communications connect the device to ventilation, gas shutdown and building monitoring systems. Sensor type and range are selected for the actual gas rather than treated as interchangeable.
Key Features
Multiple thresholds separate warning, alarm and fault conditions.
Local audible and visual outputs alert personnel at the room entrance.
Remote signals support ventilation and gas-isolation interlocks.
Customer Product Concerns
Gas hazards can be invisible, so personnel and control systems need clear local indication plus dependable remote action.
One detector cannot accurately measure every gas.The sensing technology and range are selected for the target gas and environment.
A local alarm may not reach an unoccupied control room.Relays, analog output or digital communication transmit alarm status remotely.
Sensor drift can hide a developing hazard.Scheduled calibration and fault supervision identify loss of measurement confidence.
Ventilation must respond before a high-level alarm.Separate warning and alarm thresholds stage ventilation and shutdown actions.
Typical Applications
Process gas roomsCleanroom utility chasesLaboratory gas cabinetsChemical storage areas
