Multi-branch residual current electric fire detectors produce electrical fire control system manufacturers

Electrical fire monitoring equipment for small and medium electrical fire control system design, adopt the embedded CPU as the core control chip. Via CAN bus or RS485 bus with this electrical fire monitoring detector data communication, the device uses LCD display with fault records check, data print, fieldbus communication, standby power automatic switching, alarm threshold settings, sound and light alarm and user management functions. Monitoring circuits: Maximum 512 monitoring points Display: LCD Chinese display, operating voltage: AC 220V ± 20% 50Hz storage record: up to 256, means of communication: RS485 bus Working environment: Temperature -10 ℃ ~ 55 ℃, relative humidity ≤90%, altitude ≤2000 meters Dimensions (mm): 145 * 95 * 72 (length x width x height)
