CCTV Security System Integrator

Main technical parameters
      ● Alarm point of SF6 concentration exceeding limit: 1000ppm, accuracy <

±5%；

● O2 concentration detection range: 0-25%, anoxia alarm point: 18%,

accuracy <± 0.5%；

● Temperature display range:-20 ~+99℃, accuracy < ±0.5%；

● Humidity display range: 0 ~ 99% RH, accuracy < ±3%;；

● Input power supply：AC 220V±20%；

● Alarm output contact power：AC220/5A；

● Fan output contact: 380V/15A (three-phase) or 220V/15A；

● Fan startup: When O2 content is ≤19.6% or SF6 gas concentration more

than 1000ppm, the fan will be started automatically, and the startup time of

each time will be set automatically according to the time period. The fan can be

controlled manually or forced to start；

● Mass alarm information storage design;

● Five large-capacity alarm contact outputs.

● SF6 and O2 transmitters adopt imported original sensors with long service

life；

● Low SF6 gas detection alarm error < 1%, oxygen alarm error < 0.5%；

● The fan controller can control the original fan.
