All power wiring must be completed by a licensed electrician and conform to the National Electrical Code,
ANSI/NFPA 70, and local codes and regulations.
The Access Door Module must be powered by the UL listed, 24VAC, 50/60 Hz Basic Electric transformer,
Model 7511CBDH, or equivalent. Connect low voltage power (24VAC) from the UL listed transformer to the
AC power terminals, marked as 24~.
•
The Access Door Module needs to use its own dedicated transformer as its 24 VAC
power source. You may not connect several controllers to the same transformer.
•
Use 14 AWG minimum for wiring the AC in (i.e.120VAC) side of the UL listed
transformer, per NEC requirements.
•
Keep adequate spacings between battery, power limited field wiring and AC in.
Suggest using UL recognized cable ties. Minimum .25” separation must be provided.
•
Use proper strain relief for any flexible wiring.
•
Use bushings on rough surfaces to protect cabling from abrasion.
•
Do not wire power cord behind electrical enclosure.
•
All terminals are acceptable for Class 2 Circuit connections only
•
Use copper conductors only
•
Apply minimum 6.0 lb-in torque for tightening field wires into the terminal blocks

APPLICATIONS
)
The Access Door Module has been designed with a battery circuit to provide the option of both battery
charging and battery backup for the controller. The battery backup supplies power to the controller, its
output devices (if power from the board), and Auxiliary power connections. Battery backup should be used
when using Magnetic Locks on any doors that you would like to keep locked when there is a power failure or
having the Access Control System be functional in the event of a power loss.
The battery charging circuit has been designed for the following battery specifications:
•
7 Amp Hours
•
Sealed Lead Acid battery only
•
Capable of both a trickle charge and bulk charge
•
Use supplied 0.25” Faston Lugs for connecting battery
Using a 7 AH Battery, the table below shows approximately how long the battery will last when fully
charged. (Not evaluated by UL)
Lock Duty (Battery Full Charge)
Battery Back-up Time (hours)
No lock activity, with Access System Manager backed-up
8
50% duty lock activity, with Access System Manager backed-up
5
100% duty lock activity, with Access System Manager backed-up
4
No lock activity
12
50% duty lock activity
6
100% duty lock activity
4
Note: Battery back-up times are approximations based on loads specified with a new battery. Old
batteries will not perform as well due to normal battery degradation.
