The siren/sounder may require a specific resistor as determined by the manufacturer, otherwise, 2GIG recommends a 820 ohm resistor for low current sounders.
Enable Q21 (1-3) to supervise external siren wiring
Bell output is 6-12 VDC @120mA maximum
resistor in blue:For an alternative to a wired bell/siren, you can also use a indoor/outdoor 100db/105db zwave siren/strobe (up to 240 zwave devices can be used on panel, which includes siren/strobes)
