Maximal D Series Overview: Maximal Access Power/Controllers distribute and switch power to access control systems and accessories. They convert a 115VAC 60Hz input into sixteen (16) independently controlled 12VDC or 24VDC Class 2 Rated PTC protected power-limited outputs. The outputs are activated by an open collector sink or normally open (NO) dry trigger input from an Access Control System, Keypad, Push Button, REX PIR, etc.
• Automatic switch over to stand-by battery when AC fails. • Zero voltage drop when unit switches over to battery backup (AC failure condition). • Short circuit and thermal overload protection with auto reset. • Green AC input and red DC output LED indicators on power supply board(s). • AC fail supervision (form “C” contact rated @ 1A/28VDC). • Battery fail and battery presence supervision (form “C” contact rated @ 1A/28VDC). • Enclosure accommodates up to four (4) 12VDC/12AH batteries.
8. 9. 10. 11. 12. (b) Open Collector Sink inputs: Connect the access control panel open collector sink positive (+) to terminals marked [IN] and the negative (–) to terminals marked [GND]. Fire Alarm Interface options (Figs. 8-12, pg. 14): A normally closed [NC] or normally open [NO] input trigger from a fire alarm control panel or a polarity reversal input from an FACP signaling circuit will affect selected outputs.
Maintenance: Unit should be tested at least once a year for the proper operation as follows: FACP Supervision: To ensure proper connection and operation of the Fire Alarm disconnect hookup. Please follow the appropriate procedure below: Normally Open Input: Placing a short between terminals marked [T] and [+ INP] will trigger the Fire Alarm Disconnect. Remove the short to reset. Normally Closed Input: Remove the wire from terminal marked [INP –] will trigger the Fire Alarm Disconnect.

NEC Power-Limited Wiring Requirements for Maximal3D: Power-limited and non power-limited circuit wiring must remain separated in the cabinet. All power-limited circuit wiring must remain at least 0.25” away from any non power-limited circuit wiring. Furthermore, all power-limited circuit wiring and non power-limited circuit wiring must enter and exit the cabinet through different conduits. One such example of this is shown below. Your specific application may require different conduit knockouts to be used.
NEC Power-Limited Wiring Requirements for Maximal5D: Power-limited and non power-limited circuit wiring must remain separated in the cabinet.
