Duty Cycle - Silvercrest Smart Home HmIP-SWDM-B2 Operating Instructions And Safety Instructions

HmIP-SWDM-B2

11.3 Duty cycle

The duty cycle describes a legally regulated limit on a device's
transmission time in the 868 MHz range. The aim of the regulation is
to guarantee the functioning of all devices operating in the 868 MHz
range. In the 868.0–868.6 MHz frequency range that we use, the
maximum transmission time for any device is one per cent per hour
(that is, 36 seconds an hour). When the one percent limit is reached,
the devices are no longer able to transmit a signal until the time limit
has passed. In accordance with this guideline, SilverCrest Smart Home
powered by Homematic IP devices are developed and produced in
full compliance with all relevant standards.
In standard mode, the duty cycle is generally not reached. However,
in certain cases, it may be reached during initial use or installation of
a system due to the increased, radio-intensive teach-in processes. If the
duty cycle limit is exceeded, the device LED (C) will emit a long red
light and the device may stop working temporarily. The device will
then start working again after a short time (one hour maximum).
