INSTALLATION MANUAL
V.1.0 R SERIES

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.

CONFIGURATION R SERIES
Rneeds to be configured by the iOS Latch Manager
App before use.
Download the Latch Manager App, login with the cre-
dentials provided by Latch, and follow the on-screen
instructions.
- Mag-lock’s require a separate power supply to fail
secure (stay normally closed) in the event of power
failure to R.
- Electric strikes also require a separate power supply
to fail secure if power is required to unlock the strike.
- We recommend using a voltage protector for electric
strikes and mag locks.
Note: If you would like your door to have scheduled
opening hours, please contact Latch for more infor-
mation.
IMPORTANT
REGULATORY COMPLIANCE
Federal Communications Commission (FCC) Compliance Statement
This device complies with part 15 of the FCC Rules. Operation is subject to the following conditions:
(1) This device may not cause harmful interference and (2) this device must accept any interference received,
including interference that may cause undesired operation.
CAUTION: Changes or modifications not expressly approved by the manufacturer responsible for compliance
could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B device, pursuant
to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy
and if not installed and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by one or more if the
following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected
• Consult the dealer or an experienced radio/TV technician for help
Industry Canada (IC) Compliance Statement
Operation is subject ot the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference, including interference that may cause undesired operation of the
device.
To satisfy RF exposure requirements, this device and its antenna must operate with a separation distance of at
least 20 centimeters from all persons and must not be colocated or operating in conjunction with any other
