b) Alarm dialler’s alarm calls
If there is cause for an alarm, the FHZ1000 first calls telephone number 1 and tries to set off the alarm. If this is unsuccessful,
it then calls telephone numbers 2 and 3. If an alarm could be set off, this is then confirmed (a checkmark appears on the
display).
The alarm signal is a tone sequence, which comprises low (‘T’) and high (‘H’) tones.
Ö
The alarm dialler can be used by the FHZ1000 as well as by the control centre of the ‘HMS 100 home detection
system’.
When an alarm call is made via the alarm dialler the control centre is first identified so that it is clear which control centre
is giving the alarm.
Tones are used for this identification: After the alarm dialler’s call is answered, 1 or 2 low tones (‘T’) follow. The following
assignments apply:
• ‘T’ (1 low tone) = HMS100 control centre
• ‘T’, ‘T’ (2 low tones ) = FHZ1000 control centre
Afterwards high tones ‘H’ provide information on the alarm triggers.
The following table shows the correlation between the tone sequences and alarm triggers:
• ‘H’: Low battery
The batteries of the room control, control centre or the alarm dialler are empty.
• ‘H’, ‘H’: Low temperature
One or several rooms cannot reach the minimum temperature.
• ‘H’, ‘H’, ‘H’: Reception failure
There is no more reception for one or several of the room controls.
Ö
The alarm dialler repeats the alarm signal 10 times.
c) Remote control of the FHZ1000 via the alarm dialler
Macros can be activated with the help of the remote control operation. For this purpose, proceed as follows:
• Call the device.
• The device answers after the programmed number of call signs and responds with 2 short low tones (‘T’, ‘T’).
• Now enter the 4-digit PIN.
• The alarm dialler confirms the correct PIN with a short low tone ‘T’.
• Now enter the number of the macro to be activated (1 to 4).
• The alarm dialler confirms the execution of the macro with the tone sequence ‘T’, ‘H’, ‘H’.
If the transmission fails, the tone sequence ‘T’, ‘T’, ‘T’ is given. Try it again.
• After confirmation by the ‘T’, ‘H’, ‘H’ tone, ring off to disconnect the telephone connection.
Ö
Please note:
When using the alarm dialler without a power supply (battery operated) all settings are deleted when the
batteries are removed. The device must then be registered again with the FHZ1000. If the device is connected
to a power supply, however, you can replace the batteries without having to reregister the dialler.
