sirena da esterno imago - imago outdoor siren
17
If the siren will be opened again, the red LEDs will turn on, getting back to the previous
mode. Once the external power will be detected, the siren will let the power LED flash for
20 sec. and after that, the siren will acquire the input stand‐by condition and will start its
full functioning. The
imago
siren will sound and the power LED will be flashing (300ms ON /
700ms OFF) when:
1
External power is missing (wire cutting or voltage below 7,6Vdc).
2
The input [AL] goes in alarm (Universal version
imago
only).
3
The siren is being opened and JP1 is inserted (Tamper ON)(Universal version
imago
only).
4
The siren is being opened (KS‐BUS version
imago
only).
In the case 1 e 2 the alarm condition will last until all power missing or alarm input active
will last; in any case for the maximum alarm time programmed by JP2, at the end of which
even if the alarm conditions still exist, only the power LED will keep flashing with setting
300ms ON / 1700ms OFF. To re‐activate the acoustic signal it is necessary to reestablish the
alarm condition. In the case 3 the siren activates the alarm acoustic/flashing for the
programmed time, regardless from the restoring of the tamper condition.
Programming (universal version imago only)
imago
is available with the following functions, programmable through Jumpers:
1
Tamper signal on/off (JP1)
2
Buzzer timing set‐up (3 or 10 minutes) (JP2)
3
Inputs configuration (JP3)
Programmable inputs (universal version imago only)
During the start‐up, if JP3 is inserted, the siren will delete the settings of the inputs polarity,
and will wait for its removal. When the start‐up procedure ends, the input status will be
stored in the flash memory.
Protection and tamper warning
imago
siren has two types of protection, one against the cover opening and another one
against the removal from the wall (two switches in series). The siren will check the status of
these switches and will activate the acoustic/optical warning when they are open. For
imago
universal version, when a tampering is detected the siren will open two terminal to
warn the Control Panel. The clamps relay [TAMP] reports the status of the tamper
protection switches regardless from the JP1 status. (Relay 100mA 24V max)
