1. An integrated access system, comprising:
a processor;
a memory coupled to the processor;
one or more credential transceivers;
a power monitoring circuit;
one or more light emitting diodes;
a communication interface;
a proximal motion detection circuit;
a lock interface configured and disposed to operate an electronically activated lock; wherein the memory contains instructions, that when executed by the processor, perform the steps of:
detecting a low power condition from the power monitoring circuit;
sending a low power condition message to a remote computing device; and
setting a lock force reduction mode in response to the low power condition; and
reverting the lock force reduction mode for a predetermined time interval, in response to detection of motion from the proximal motion detection circuit; and wherein the memory further contains instructions for setting the lock force reduction mode that cause the processor to perform pulse width modulation of a power signal supplied to the electronically activated lock, wherein the total cycle of the power signal has a value ranging from 400 milliseconds to 700 milliseconds.
