4.2. Alarm triggered
The alarm can be triggered by three different operations:
Keypad Alarm Pushbutton Pressed.
The trapped passenger must press the pushbutton for 5 seconds. The equipment will check the lift status and, if
applicable, will trigger the alarm (see item 4.3. Alarm filtered). The alarm pushbutton contact should be in
accordance with the ID_16 “Operating Mode” parameter which, by default, will be normally closed (NC), so that
the circuit opens when the pushbutton is pressed.
Fonomac 3 will indicate that the alarm process has started through a yellow LED and the system will try to connect
with the alarm call centre. If connection fails, it will try again and again until it connects. There is a 2-minute wait
between each attempt. Fonomac 3 will make three attempts to reach the call centre at each of the three
programmed numbers. Should connection fail after the third attempt made to the last number, the process would
start again from the first number and it would continue indefinitely until communication is made and the
corresponding call is registered.
Alarm Pushbutton on ceiling or under car floor pressed.
The process would be similar to that of the keypad alarm pushbutton although no previous filtering would occur,
thus directly triggering the alarm. These pushbutton contacts will always be NC.
Fonomac 3 has a specific telephone number for calls coming from these pushbuttons. If the user does not want to
use this specific telephone number, calls will be automatically redirected to the list of alarm telephone numbers.
Batteries not working properly or flat.
The equipment has an internal emergency power supply and continuously checks the status of its batteries.
Should the equipment detect incorrect operation or extended discharge of batteries, it will call the alarm centre
sending the corresponding alarm message, thus ensuring that, from that moment on, it has an hour of life
maximum. This alarm is not subject to filtering and the calling process will be similar to that described in the
previous items. In addition, there is a specific telephone number for calls made for this reason.
Should you not require this function, just deactivate it by assigning the ID_32 “Trigger Low Battery Alarm”
parameter value “0” (Deactivated).
