location, as high as possible, away from water and rain sources.
Use four (4) screws to attach the siren housing to a solid wall.
Step Two: Wiring (refer to figure 1 and 2)
1. Disconnect DC Power and battery at control panel
2. The Bella is compatible with most alarm panels, operates with or without battery.
If an EasyLoader panel is connected: Verify that address 072 option 1 (Bell Mode) is
programmed (should be as it’s Factory Default).
Bella I: Connect the +TRG from Bella to +SIR, the –SIR to –SIR, or apply 12V DC.
Bella I AS: To activate the strobe apply –V from the SLO output to –STB at the siren.
To activate the strobe with siren at once connect the –STB to –SIR both at siren.
-SIR - DC input to drive the siren. Connect this terminal to the control panel –SIR.

Step Three: Powering-up
1. After the wiring to the panel is completed, re-check the polarity
2. Close the siren cover to prevent alarm caused by the Bella tamper switch
3. Power-up the control panel.
Step Four: Testing
Close the Bella box. Generate alarm condition; check if siren and strobe are
functioning correctly. Bella circuitry is protected against high voltage supplied (over
14V) to +TRG, if such supplied the siren operation is blocked.
Open the box for Tamper alarm test, verify alarm generated. Close the cover and
tight the screw mounted in the front face. Note: Consider strobe lens cleaning
service once a year.
