Module Models:
HRAM-1032 MAIN ANNUNCIATOR CHASSIS (32 Display Points)
20 to 31 VDC (filtered or full-wave-rectified)
Sealed membrane-like buttons and LED indicators.
Local Buzzer, Indicators (AC-On, Common Trouble, Remote Failure, Aux. Disconnect, Acknowledge, General
Alarm, Signal Silence, Test/Config Mode), and Controls (System Reset, Lamp Test, Fire Drill, Aux. Disconnect,
Buzzer Silence, Signal Silence, General Alarm, Acknowledge).
Buzzer Silence activation silences the main fire alarm panel buzzer and all attached annunciator buzzers.
Annunciation of up to 32 Points.
Expandable by using up to four HRAX Modules.
Standby: 50 mA Max., All LED’s “On”: 150 mA Max.
HRAX-1048 ADDER ANNUNCIATOR CHASSIS (48 Display Points)
Interconnect via one ribbon cable to HRAM-1032 or to previous HRAX-1048.
Annunciation of up to 48 additional Points.
Standby: 15 mA Max., All LED’s “On”: 100 mA Max.
Current Drain for Battery Calculations:
The maximum normal current drain will be during Lamp Test when all lamps are illuminated on one chassis at a
time. Thus the currents are ...
Normal Standby =50 mA +______________ X 15 mA = _________
(number of Adder Chassis)
Maximum =150 mA +______________ X 15 mA = _________
(number of Adder Chassis)
The Normal Standby Current is used for Battery Size Calculations (see the Fire Alarm Control Panel manual) and
includes the current drain for the Trouble Buzzer, Trouble LED, and one Alarm LED. The Maximum Current is used
to calculate the wire size (see the Wiring Instruction).
