Product Overview:
Model SSK-ZL-N16-E Combustible Gas Alarm Controller is an indoor standalone bus-type controller. It receives, displays and transmits alarm signals from gas detectors to realize gas leakage monitoring, alarm notification and linkage control.
It is suitable for indoor gas leakage monitoring applications (such as commercial kitchens, boiler rooms, chemical workshops, storage areas and other indoor non-explosion-proof locations). Used together with gas detectors, it provides early warning of leakage risks and prevents safety accidents such as explosion and poisoning.
Product Features:
※ LCD display with full Chinese menu operation.
※ Single-loop 2-wire bus (M-Bus) communication with non-polarized signal design. It comes with automatic protection, featuring strong anti-interference capability, cost-effective wiring and easy installation.
※ Automatic fault detection, which accurately indicates the fault location and fault type.
※ Automatically identifies detector types and alarm points. Supports monitoring of multiple detector types (%LEL, %VOL, PPM) within one system without manual configuration.
※ Built-in data storage. It saves 100 power-on records, 100 power-off records, 100 reset records, 100 controller time modification records, 1000 fault alarm records, 1000 fault alarm recovery records, 1000 combustible gas alarm records, 1000 combustible gas alarm recovery records, 100 shield records and 100 unshield records. Data will not be lost upon power failure (the time stamp of each record includes year, month, day, hour, minute and second).
※ RS485 bus communication interface (standard Modbus/RTU protocol). It supports networking with host control systems for remote monitoring, greatly improving the timeliness and accuracy of monitoring.
※ Built-in 2 sets of relay contact outputs for linkage control of exhaust fans, solenoid valves and other devices.
