The
LATCH R
is a proximity reader, keypad,
and wireless entry access control system. The
R can operate as an entire standalone access
control system or as a proximity reader for
integrating into existing systems.
The R has an NO relay that can handle locks
and devices up to 1.5A at 24VDC. The system
has 3 flexible IOs which can be configured to
interface with inputs (such as request-to-exit
switches, motion detectors, open-door detec-
tors, and admin switches), or outputs (such as
audible alarms, small locks < 350mA, light
indicators, alarm-panel signals, and tamper
signals).
Tamper is detected using a 3 axis acceler-
ometer, and the signal can be configured as
an IO output or sent via ethernet. A heartbeat
event can also be sent with critical telemetry
via wifi or ethernet.
The R communicates with existing panels
using 26/32-bit Wiegand Communications
via Wiegand are electrically isolated from
processor circuitry.
There are 2 cables routed out the back of the
product: an 8 conductor and 10 conductor.
The 8 conductor cable is 4 sets of 24 AWG
twisted pair used for ethernet communica-
tions. The 10 conductor houses 22 AWG
wires for power, communications, IO, and
relay connections.
Wi-Fi, Ethernet, or Bluetooth can be used to
sync new user credentials to device memory.
Credentialing and operational management
are managed using the Latch Manager Web-
site and iOS App. Device setup is done using
the Latch Manager App.
