Performance features

  • Suitable for GSM dialling and control unit (12 V /1.5 A)
  • Provides a stand-by time of at least 12 hours in the event of a power failure for all functions
  • Mounting instead of the original housing cover
  • Battery built into the cover

The original lid of the existing GD-04K is removed and replaced with the new lid with batteries installed. No difference is visible from the outside. During normal operation, the batteries in the lid are charged and kept full at all times; in the event of a power failure, the system immediately switches to the emergency power supply without being noticed.
Even if entire streets and residential areas suffer a power outage, most of the cellular operators' transmission towers continue to operate. Events that occur now, e.g. a burst water pipe or similar, are still detected by an SHT 5000 with an inserted 9 V block and forwarded to your cell phone via GSM.
