Notification Appliances—PS12/24ADA Series Signaling Strobe and Sounder 7
All models can be powered using Full-Wave Rectified (FWR), unfiltered
(unregulated) power supplies. However, if the power supply is
unregulated, the notification appliance must be compatibility listed for use
with the fire alarm system. If the power supplied is from a regulated
power supply, no compatibility listing is required. In addition, follow the
guidelines listed below:
●
Under no circumstances can PS24ADA series devices input voltage
exceed 33 VDC or be less than 16 VDC peak when using a regulated
power supply. When using an unregulated power supply, the range is
16-33 VRMS.
●
Under no circumstances can a PS12ADA or MASS12ADA series
device input voltage exceed 18.7 VDC or be less than 8.5 VDC for a
regulated power supply. When using an unregulated power supply,
the range is 8.5-18.7 VRMS.
