EST3 Installation and Service Manual 3.39
Power from an AC source
Description of the application
By AC power, we mean that the CRC provides the power to
operate the electric door strike or maglock by using a 16.5 Vac
transformer (model CRCXF). This supply can provide
continuous power to the door strike or maglock, and also power
the CRC.
Using an AC source:
• Limits power drawn from the control panel
• Supports continuous duty locks
• Supports schedules with unlock periods
Note: Be sure to check the installation sheet for the CRC and
CRCXM—Card Reader Controller Installation Sheet (P/N
387625) for a list of applications that prohibit the use of the
CRCXF.
A typical CRC using AC power is shown in Figure 3-14.
