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.
