Specific-System - Alarms and Detection Unit
Keep your employees and equipment safe with combustible, corrosive, and toxic gas alarms. Gas alarms are used to detect and alert persons of the presence of corrosive and/or combustible gases including hydrogen sulfide (Hâ‚‚S) and sulfur dioxide (SOâ‚‚), nitrogen dioxide (NOâ‚‚), and oxygen (Oâ‚‚). The alarms may be used in hazardous areas and can be integrated into Specific Systems HVAC units even in Class I, Div 1, Groups B, C, & D environments.
Use of gas alarms is often required in:
- Refineries
- Offshore faclities
- Pharmaceutical production facilities
- Textile facilities
- Electric power distribution buildings (MCC, etc.) in various applications
Applications are available for single or multiple types of gases.
- Pre-wired, installed, and are factory calibrated.
- Another calibration may be necessary for individual environments and specifications.
- Alarms are typically wired to shut down the HVAC and pressurization units and seal off the area from outside air via a damper.
- Wired for high level, low level, and fail using Form C contacts allowing remote notification of the alarm.
- Capable of non-intrusive calibration via the monitor, allowing the device to remain Class I, Div. 1, Group C & D certified during adjustment.
- Catalytic bead or infrared technology with sensors mounted to meet the customer’s requirement.
Alarms are available to detect the presence of combustible gases such as hydrogen, carbon-based gases such as methane, and an abundance or shortage of oxygen. Also available are alarm systems for:
- Smoke detection
- Toxic gases
- Corrosive gases such as H₂S, SO₂
- Carbon monoxide (CO)
- Others
Monitors are encased in NEMA 7 and NEMA 4X explosion proof housings and are CE and UL certified.
