Wireless doorbells
Functionalities, error checking, connection problems
Can I connect several electronic doorbells in parallel?
It is possible to connect several electronic doorbells in parallel. Please ensure that the total current consumption does not exceed the capacity of the bell transformer. For further information, please refer to the instructions for the devices (can be found online on the respective product detail pages) or contact our Customer Service.
How do I open the Mistral wireless bell push?
Two holes can be seen on the narrow side of the bell push. Here you will find the screw plugs, which you can open with the enclosed 2 mm Allen key. Please refer to the description on page 5 of the instructions.
How is the transmitter paired with the receiver?
In general, depending on the model, a button on the doorbell must be pressed for approx. 3 seconds. A green LED on the doorbell then lights up for 30 seconds. The button on the bell push must be pressed once during this time. Successful pairing is acknowledged with a call signal. If the process is not successful, the green LED on the transmitter will change to a flashing display after approx. 15 seconds and then go out. In this case, please try the procedure with new batteries in the transmitter and/or receiver. Please refer to the description on page 14 of the instructions.
How do I connect the Mistral wireless bell button for call forwarding?
The wireless bell push is connected in parallel to the existing wired doorbell using terminals C and T. Insert the batteries. Attention: the voltage must not exceed 12 V. Please refer to the circuit diagram and description on page 7 of the instructions.
My wireless doorbell is not working. What tests can I carry out?
There is no fault if
a) the radio bell button flashes red 7 times after being pressed
b) the doorbell plays a melody after the T2 button is pressed
The receiver must play a melody to the end without interference when the T2 button is pressed, otherwise please replace the batteries. Alternatively, check whether the maximum range for the wireless doorbell set has been observed.
If necessary, pair the transmitter to the receiver again.
Please refer to the description on page 14 of the instructions.

How many repeaters can I use with the wireless doorbell?
You can connect a maximum of two repeaters in series.
How do I install and connect the Mistral repeater?
The MISTRAL repeater can be operated either via battery or a fixed power supply. To pair with the wireless bell push, press the button in the repeater for 3 seconds and then press the wireless bell push.
Can I operate the Mistral wireless push button without battery?
If you want to replace the batteries, you must supply the transmitter with a permanent direct voltage of 6 - 12 V DC at terminals "V" and "0".
This voltage source must not be used for triggering (control) at terminal "T" at the same time!
Please refer to the description on page 6 of the instructions.
I have a large property. Which wireless doorbell has the longest range?
The range depends on the wireless bell push. I.e. if the SE03.0 wireless bell push is used, the ECHO and MISTRAL wireless gong series have a range of 250 m (in free field). If the wireless bell push 03.1 is used, the range is 500 m (in free field). The range can be extended using a repeater.
Can I operate the Mistral wireless doorbell with my old wireless doorbell 396?
Unfortunately not. The wireless doorbell 396 is not compatible with any wireless doorbell of the new generation. Simultaneous control of a 396 transmitter and a MISTRAL transmitter is also not possible.
Why does the CALIMA wireless doorbell emit two beeps after the melody?
Possibility 1: The batteries in the wireless doorbell do not have the required voltage. Common rechargeable batteries often do not have the required voltage, but only 1.2 V. Only use batteries or rechargeable batteries with a voltage of 1.5 V.
Possibility 2: The battery power is low. Insert 4 new 1.5 V batteries (type AA).

You can connect an unlimited number of wireless doorbells to one wireless doorbell push-button.
How many wireless doorbell buttons can I connect to my wireless doorbell?

Why does the LED of the wireless doorbell button on the CALIMA wireless doorbell not flash after being pressed?
Option 1: The batteries in the wireless bell push do not have the required voltage. Insert 2 1.5 V batteries (type AAA).
Possibility 2: The batteries are not inserted correctly (incorrect polarity). Insert the batteries with the plus sign in the direction of the embossed "+" in the battery holder.
Why does my wireless doorbell sound two additional tones after playing the melody?
The double attention tone at the end of the call melody sounds to indicate an (almost) empty battery in the wireless doorbell. In addition, an attention LED flashes on the front of the radio chime.
Corresponding pictograms for the transmitter and wireless doorbell are printed on the left-hand side of the receiver.

How can I play my own melodies on the doorbell ECHO?

Why doesn't my flush-mounted doorbell (120WS or 230WS) play the complete melody?
Check whether the flush-mounted doorbell has a fixed power supply. A push-button command is then switched from this voltage source to channel C1 and/or C2 to start the doorbell. A connection with only one keyed voltage and only two wires is not correct.
Please refer to the description on page 3 of the instructions.
