The Model 8420 X is a microprocessor based fixed gas detection system designed to accept the input from remotely located Oxygen, Combustible or Toxic detector transmitters. The system is designed to provide continuous round the clock monitoring for a variety of common atmospheric hazards.

The Model PIC 6002 is a micro controller based Intelligent Indicator controller accepts 4 20 mA input from remotely located transmitter as well as provides 24 volts DC to power the same. It utilizes a point-to-point wiring architecture whereby each Transmitter / Detector Hez id, Alarm/ shutdown device or remote system is individually wired to the control unit. This is the best choice for: >mall systems, where the sensors are located in relative close proximity to the control unit.

It utilizes a point to point writing architectures whereby each detector head, alarm / shut-down device and remote system is individually wired to the control unit. This is best choice for small systems, typically less than 20 points, where the sensors are located in relative close proximity to the central control unit. The system is designed for easy expansion by means of plug in sensor modules. Remote 98 series transmitters are available in non explosion proof or explosion proof versions. Both versions can be with or without digital readouts.

Endee Model 8420 X rack / panel mount control enclosure along with Micro controller based digital control modules is designed to serve as a host control system for remote mount gas detection sensor transmitters. The single channel modular designed can be configured for any combination of gases. All control modules are plug in front panel accessible for easy maintenance and repair. A "Blank Plate" can be installed on any unused channel until that channel is needed at some future date.

The Model 8420 X includes an integral and modular power supply, three digit indicator serves as both a power on indicator and a direct reading display of the gas concentration. Alarm set points are software adjustable in 1 PPM / % increments across the range of detection. The reset switch reseta all alarm relays.
