Installation Instructions
- Mount the SirenDriver in desired location (mounting hardware included).
- Connect 4 Ohm or 8 Ohm speakers to terminals marked [SPKR] (Figs. 1, 2 below). See suggested speaker wiring diagrams below.
- Connect 6VDC to 12VDC from output terminals on control panel or other desired power source (observing polarity) to [GND] and [STY+] or [YLP+] on siren driver.
Note: Steady tone overrides yelp tone if both channels are triggered simultaneously.
Typical Speaker Wiring Diagrams
Two (2) Speakers, 8 Ohms each
Three (3) Speakers, 8 Ohms each
Four (4) Speakers, 4 or 8 Ohms each
Two (2) Internal/External Hook-up
Fusing External Speakers:
Speakers that are accessible from outside the building should have a 2.5A fuse
placed in series with the speaker leads so that any attempt to short the
speaker leads will blow the fuse on that speaker while other speakers will
continue to operate.
