The table shows the input current taken by the various units. 
The current levels shown above are for the 440Hz Continuous tone @ nominal input voltage.  
Nominal current at nominal voltage.

 

Table 1: Electrical Ratings.

 

It is important that a suitable power supply is used to run the equipment. The power supply selected must have the necessary capacity 
to provide the input current to all of the units. 

 

The above table shows the input current taken by the various sounders and shows the maximum voltage at which the sounders can 
be operated: 

 

The input current will vary according to the voltage input level and the frequency of the tone selected. 

 

2.  Warnings 

  

 

  DO NOT OPEN WHEN AN EXPLOSIVE ATMOSPHERE IS PRESENT 

  DO NOT OPEN WHEN ENERGIZED 

  POTENTIAL ELECTROSTATIC CHARGING HAZARD – CLEAN ONLY WITH A  DAMP CLOTH 

  COVER BOLTS CLASS A4-80 

  USE HEAT RESISTING CABLES AND CABLE GLANDS (RATED 110°C) AT AMB. TEMPERATURES OVER 

40°C
