E-Series Wall-Mounted Combustible Gas Alarm Controller Multi-Probe Types
1. Product Overview
The RJZ901 of the E series wall-mounted combustible gas alarm controller is used to detect the content of combustible gases or toxic gases in the air. It supports the use of divided-wire detection probes, RS485 detection probes and POWBUS detection probes, and can centrally control multiple points at the same time. This system uses a microprocessor as the control unit. When the concentration of combustible gases in the environment reaches or exceeds the preset value, the controller will immediately send out audible and visual alarms, and can drive the exhaust fan or other peripheral devices to act through the relay to prevent explosion and fire accidents, thus ensuring lives.
2. Product Features
(1) Communication bus: ≥RVSP - 2×1.5mm² shielded twisted pair
(2) Power supply line: ≥RVVP - 2×1.5mm² shielded cable or RVV - 2×1.5mm² flexible copper - core sheathed wire
(3) 4 - 20mA line: ≥RVVP - 3×1.5mm² shielded cable or RVV - 3×1.5mm² flexible copper - core sheathed wire
3. Application
This system can be widely applied to places that needs fire prevention and explosion protection, such as factories, oil depots, liquefied petroleum gas stations, coal gas stations, gas stations, spray painting booths, etc., for safety monitoring and alarming.
