Overview
The SAFETAK GC90S-NH3 (1000ppm) Single-point Wall-Mounted Gas Monitoring Alarm is a monitoring device for detecting ammonia (NH3) in non-explosion-proof environments. It is powered directly from a 220V AC power supply, has a corrosion resistant die-cast aluminum housing, Protection Rating to IP66, and can be connected to a Miscellaneous control linkage via an optional relay signal output.
Features
1. Ultra-high Protection Rating: IP66 protection, good waterproof and dustproof performance, die-cast aluminum shell corrosion resistance, with strong electromagnetic Shielding performance.
2. High product mass: Sensor adopts international good brand, high detection accuracy and short reaction time.
3. High-intensity, diverse alarm system: the product has an audible alarm of up to 120dB; 360 ° high-intensity light alarm, which is clearly visible at a distance.
4. Two display modes are available: LCD and LED.
5. Humanized design: Maintain the menu password lock to prevent misoperation; optional relay signal output can be connected to other control linkage devices.
Principle
The alarm uses electrochemistry principle Sensor to continuously detect the target gas. The detected gas concentration signal is displayed on the display screen after processing. When the concentration reaches the preset low alarm point (25ppm) or high alarm point (50ppm), the device will trigger sound and light alarms and output corresponding control signals.
Applications
Petroleum, petrochemical, metallurgical and other industrial sites of non-explosion-proof places, gas stations, boiler rooms, laboratories, Food processing and other sites and office environments.
Standards
GB12358-2006 "Working environment Gas detection alarm instrument General technical requirements"
Steps
1. Install the equipment at the target location and connect it to the 220V AC power supply.
2. After the equipment is powered on, it enters the working state and starts to continuously detect the ammonia concentration in the environment.
3. Observe gas concentration readings in real time through the display (LCD or LED).
4. When the concentration exceeds the preset alarm value, the device automatically starts the sound and light alarm.
5. If you need to perform maintenance settings, you need to enter the password to enter the maintenance menu for operation.
6. Optional external control devices can be connected as required (e.g. via 4-20mA signal or relay signal output).
Notice
• This product is suitable for non-explosion-proof environment, please do not use it in places with explosion-proof requirements.
• When installing and maintaining, ensure that relevant safety operating procedures are followed.
• When performing maintenance menu operations, a password is required to prevent misoperation.
• Please ensure that the working Ambient Temperature is between -20~ 50 ℃, Humidity ≤ 95% RH and no condensation.
• Regularly calibrate and maintain equipment to ensure detection accuracy.
When connecting the external control device, please confirm the signal output type (4-20mA or relay switch) and load capacity (relay signal is 220V 3A).
