Consumption:     120 

mA 

RMS 

maximum 

Appliance Input Level:          0.5 V RMS or 25 V RMS (Switch selectable) 

Appliance Input Impedance: 

0.5-V Setting: 
   Greater than 400 Ohms, or equivalent to less than 
   1/1000 W (0.001 W or 1 mW) load 
  
25-V Setting: 
   Greater than 20 kOhms, or equivalent to less than 
   1/32 W (0.03125 W or 31.25 mW) load 
 

Sound pressure level measurements were made at 16 VDC with audio inputs of 0.5 V RMS in the 0.5-V setting and with 25 V RMS 
in the 25-V setting. Current measurements were made at 33 VDC with audio inputs of 0.5 V RMS in the 0.5-V setting and with 
25 V RMS in the 25-V setting. 
 

WARNING:  THIS APPLIANCE WAS TESTED TO THE OPERATING VOLTAGE LIMITS OF 16-33 VOLTS 

REGULATED POWER. DO NOT APPLY 80% AND 110% OF THESE VOLTAGE VALUES FOR SYSTEM OPERATION. 

 

CAUTION:  

The

 

Speaker

 

is not designed to be used on coded systems in which the applied voltage is cycled on and off. 

 

SETTINGS: 
 

The switch on the PCB (SW1) is used to select the input voltage and sound output level, see Figure 1.
