0 C to 50 C) 
High Voltage Output  29.1 V @ 3.3 A  
Output Current Limit 
1.4 A (For 6.2 – 18 Ah battery) 
3.3 A (Default; for 18-50 Ah battery – Canadian;  
for 18-110 Ah battery – U.S.) 
 
Notes: 
  The battery circuit is supervised. 
  When it is necessary to activate large numbers of output devices on IDNet peripherals  
(such as piezo sounders), the output voltage is increased to 35 V to provide sufficient voltage at 
the end of line to activate the piezo.  The higher voltage state is an alarm condition for the 
purpose of standby battery calculation.  The 30 V output is the normal condition and is used to 
prolong battery standby.  The system CPU activates the boost feature when 10 LED, Piezo or 
other outputs are activated.  
  AC power must be provided to the Power Supply from a dedicated branch circuit.
