Compliance Notes:         
Note 1: For UL294 Compliance when using 8 output PDB boards with fire trigger: Fire Alarm disconnect wire length must be less than 
98.5 ft. (30m) 
Note 2: For ULC-S318 compliance, the power supply battery fail line must be connected to and monitored by a control panel trouble 
zone 
Note 3: AQDX Series uses a standard power supply enclosure, not an attack proof enclosure. As such, they should not be used to power 
a mercantile bell 
Note 4: When using a battery that is not housed inside the power supply enclosure, the battery leads require protection from the 
enclosure via the use of conduit. The enclosure shall be UL Listed to the above categories and shall have sufficient space to 
accommodate the standby batteries.  
Note 5: When using AQDXB modules in another enclosure, minimum standard spacing between live electrical circuits shall be taken 
into account 
Note 6: Model AQD1B power supply requires a low battery disconnect module (model# BDM) manufactured by Life Safety Power. This 
device is required to provide the required battery disconnection for ULC-S318.  
Note 7: Power supplies shall be installed in accordance with the National Electrical Code, ANSI/NFPA 70, Canadian Electrical Code, or any 
other applicable codes 
Maintenance 
The power supply and standby batteries should be tested at least once a year as follows: 
1.  CHECK LEDs for normal state: AC ON Green, Trouble Normal ON Green (Amber LED indicates trouble), DC ON Red.
