NSGV GSE-NCM-LL1 DUAL GAS DETECTOR
CABON MONOXIDE – NITROGEN DIOXIDE SPECIFICATION
GENERAL DESCRIPTION:
The GSE-NCM-LL1 is a dual gas detector capable of sensing both carbon monoxide (CO) and nitrogen
dioxide. This eliminates the need for two separate sensors. This provides a safe working environment in parking garages, warehouses,
manufacturing facilities, shops, etc. The detector shall contain a semiconductor carbon monoxide (CO) sensor with temperature and humidity
compensation circuits and an electro-chemical nitrogen dioxide (NO²) sensor. The LCD display will continually display the current NO² and CO
levels in PPM. Additional features include a green “power” LED, yellow “sensor-active” LED, red “low-alert” LED, red “high-alert” LED, and red
“alarm” LED. The GSE-NCM-LL1 is ETL listed to UL3111-1.
TECHNICAL CHARACTERISTICS:
-
External Alarm Silence Button
-
Pre-punched openings for field conduit connection
-
Factory installed wiring that exits enclosure, allowing installation without opening detector
-
Fail-Safe activation of fan if detector loses power
-
NEMA 1 enclosure
-
Switches provided for field adjustment of gas detection level for low-alert, and on/off time delay for low-alert and high-alert
-
Selectable time delays from 0 to 7 minutes in 1-minute increments
-
Selectable CO detection levels from 20-55 PPM and NO² levels from 0.3 to 4.0 PPM
-
5000 square foot coverage
