Functional description
When an emergency call is triggered with the pull cord, the red light on the push-button
confirms the successful call. The emergency call is indicated visually and acoustically by
the emergency signal. In stand-by mode, a light makes it easier to find the pull cord push-
button.
For other use cases, the visual and acoustic call can be transformed into a continuous
signal, for example, using a jumper. It is also possible to disable the acoustic call.
The unmonitored call can be sent from the emergency signal via a floating contact.
Pressing the reset button stops the emergency call.
If there is no superordinate emergency power supply, the UPS module must be used. The
UPS module ensures that the emergency call is triggered even in the event of power
failure. The accumulator included is easy to replace and available as a spare part. This
emergency power supply is monitored, every disruption is reported.
In battery mode, a short acoustic signal is sent to the emergency signal every 12 seconds.
Two short acoustic signals every 12 seconds are sent to the emergency signal to indicate
an accumulator disturbance.
