The AUTOCALL Power supplies (models RPS-424
and DCPM) are solid state electronic power
supplies which provide filtered regulated DC
power to the AUTOCALL TFX series fire alarm
system. The RPS-424 converts 120Va.c. primary
power to 24Vd.c., 5Vd.c. and 15Vd.c. The DCPM
converts 24Vd.c. power from the RPS-424 to the
supply voltages necessary for the TFX family.
The power supply monitor module (module
500PSM) monitors the RPS-424 and provides
visual trouble indication of faults.
Features - RPS-424
. Converts 120Va.c. input power to d.c.
operating power
. Charges and supervises batteries
. Automatic transfer to battery during a.c. power
failure or brownout
. Unique voltage booster feature for notification
purposes
Features - DCPM
. Converts 24Vd.c. to voltages required by the
TFX family
Features - 500PSM
. Provides visual indicators for RPS-424 power
supply faults
. Mounts directly to RPS-424 power supply
. Provides addressable interface to TFX data
circuits
