Specifications

Readers: 8

 max.

Quiescent supply input

: 100mA @11.7 to 12.7Vdc (excludes 

readers and optional modules, with no relays energized).

Maximum supply input

: 590mA @11.7 to 12.7Vdc (all modules 

fitted, all board & module relays energized, excluding readers). 
Each relay on the 8DC consumes 20mA when energized.

Operating Range

: 14 to 131°F (-10 to 55°C) max. Humidity 15 to 

90% non-condensing; indoor use only.

Compliance

: EN50133, 1999/5/EC, UL 294 Access Control & 

UL1076 Proprietary Burglar Alarm Systems.

The 8DC is used to expand a database unit, by enabling direct connection of eight extra 20mA or Wiegand readers. Additional monitor 
points and auxiliary outputs are available by fitting an optional I/O Module (the module type determines the number of available monitor 
points and auxiliary outputs). 

Note: 

For information on mounting the 8DC into the cabinet, refer to the appropriate cabinet installation instructions.

UL Compliance Notes:
1). For UL1076 Proprietary Burglar Alarm Systems and Non-Stand Alone UL294 Access Control System (central monitoring 
employed) installations, Altronix AL600ULX power supply must be used for system battery supervision function.
2). When using Altronix AL600ULX power supply, the installer will need to provide a remote input to the 8DC to monitor AC power 
loss and battery supervision conditions as indicated below:
