10 Outdoor Self-Powered Siren
Automatic mode
For siren basic operation are required two wires only, as shown in figure 3: the control panel (A) must have a terminal (+N) where
13.8 V voltage (minimum 600 mA) is present on standby and no voltage in alarm; the control panel cannot detects the siren tamper,
and foam tamper (NEKA-F and NEKA-FS only) but the siren automatically activates for those events.

Automatic mode with independent management of foam tamper (NEKA-F/NEKA-FS only)
If foam tamper have to be managed by the control panel, jumpers position must be as shown in figure 4, and FT terminal of the
siren (B) must be connected to an input line of the control panel (A) that is on standby when connected to ground and in alarm
when floating (Z terminal in the figure).
