The Ksenia 'Imago' Siren box installation requires for the box to be powered by a 6V battery BEFORE connecting the bus power from the Lares panel.
Before going to site to install the Imago siren box it is recommended to check that the auxiliary battery is fully charged with an open-circuit voltage of approx 6.3-6.4V as the panel will not start up correctly if the battery voltage is low.
Once installed the battery is 'trickle charged' by the panel and kept up to operating voltage.

START UP PROCEDURE
The correct powering procedure of imago siren must initially to be done through the battery (6V 1.2Ah
Dimensions: 98x50x22 mm - not included) and then giving power (13.8 Vdc typical) coming from the Control
Panel. It is fundamental to respect this order.
Once powered, the siren will give just a single flash from its main power LED and the buzzer will sound for a
second to verify the correct functioning of all parts ; moreover the red signaling LEDs will keep flashing
(slow at 1 Hz) until the siren will remain open (tamper switches open).
After closing the cover, the LEDs will flash faster (2 Hz) for 20 sec. If the siren has been powered also from
the Control Panel, then the power LED will start to flash (period 300/700ms) for 20 sec.; the siren will
acquire the inputs stand-by condition and start its full functioning. In case you still need to connect the
power to the Control Panel, the siren will go in “low consumption mode” waiting for the external power. 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), the alarm condition will last until all power missing will last.
2) The siren is being opened.
