Exterior/interior piezo sirens
Onboard output 1 (OUT 1—terminal 9) is a 9 to 14 VDC switched, programmable
output that can handle a maximum of 1,000 mA current. The default setting (01614)
activates the output 30 seconds after a police or fire alarm condition occurs. This
allows you to connect a piezo siren without changing the output configuration
number in programming. This output is typically used for exterior siren applications.
Connect multiple piezo sirens in parallel. (For more information on output
configuration numbers, see “
Onboard options menu” on page 75.)
Note: For 24-hour backup, external power drain is limited to 90 mA (during normal
standby condition), using a 4.5 or 5.0 Ah battery, or 190 mA continuous using a 7.0 Ah
battery.
