FGD14 Safe Area Gas Detector
Safe-area fixed detector for oxygen and toxic gases with remote visual and audible alarm unit.
Key Features
- Mains version 85–265 V AC, 47–440 Hz
- DC supply version 9–36 V DC
- Remote visual and audible alarm unit
- 2 control relays (voltage-free, single-pole changeover)
- 2 user-adjustable alarm set points
- Plug-in replaceable gas sensors (electrochemical or NDIR infrared)
- Optional weather guard
Overview
The FGD14 series is a safe-area fixed gas detector for gases such as O2, CO, CO2, SO2, H2S and Cl2, featuring a remote indicator unit and an optional weather guard for added protection in harsh environments. The CO2 model uses miniature infrared sensor technology, and built-in control relays allow stand-alone operation across a wide range of applications. It must only be used where there is no risk of potentially explosive gases being present.
Working Principle
A plug-in electrochemical sensor (or NDIR infrared sensor for CO2) measures the target gas. Two user-adjustable alarm set points drive two voltage-free changeover relays, a flashing red LED and an intermittent alarm tone on both the detector and the remote indicator unit.
Applications
Benefits
- Stand-alone operation without a separate control panel
- Local and remote alarm indication
- Wide choice of gases and ranges from one platform
