The remote reader does not have its own latch relay. Using a valid card in
either reader will activate the latch relay on the
ENTRACOMP
®
28SA-Plus
.
Other devices with either a Secura Key 31-bit or 26-bit Wiegand output may be
also be connected to the Remote Reader Input. Various transmitter-type gate
openers, bar code scanners, and proximity readers are available with a
Secura Key 31-bit or standard 26-bit Wiegand output format.
When using any reader other than the SK-029W as a remote reader, be sure
to order the Secura Key “Wiegand Cable’, part number 7994995. This is
required to allow connection to the
ENTRACOMP
®
28SA-Plus
.
A popular remote reader choice is the Secura Key RK-WL long-range proximity
reader. The RK-WL reads proximity cards up to three (3) feet away. Many
drive-up applications need the convenience of long-range proximity. Connecting
the RK-WL to the 28SA-Plus makes it possible to program the system with a
PD-26 Program Deck.
Note that these other Wiegand-output devices may need their own power
supplies, since the Remote Reader output voltage varies, depending on the
input voltage as follows:
DC Voltage Out: = AC Voltage In x 1.3
OR
DC Voltage In x 0.9
Recommended input voltage to the 28SA Plus with a Remote Reader is
12 - 16 Volts AC or DC. Lower voltages will be insufficient to operate the
SK-029W reader; higher voltages will cause the reader’s voltage
regulator to run hot, which could cause early component failure.
