INSTALLATION GUIDE
R SERIES

Latch R is a proximity reader, keypad, and wireless entry system,
that can be operated as a standalone device or be connected to a
panel as part of a wider system.
Welcome to your
smartest install yet.

Only use screws provided. Other screws can cause Latch R to
disengage from the mounting plate.
The relay will revert to an open state in the event of power failure.
Take precautions when wiring fail-safe locking hardware.
Apply power only after all devices have been properly connected.
Conguration requires the iOS Manager App running on an iPhone
5S or newer.

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 o and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
Regulatory Compliance

• Connect the equipment into an outlet on a circuit dierent 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 to 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 antenna or transmitter.
Le présent appareil est conforme aux CNR d’Industrie Canada
applicables aux appareils radio exempts de licence. L’exploitation est
autorisée aux deux conditions suivantes :

Testing and Maintenance Operation
•
•Loose wiring & loose screws.
Normal operation (attempt to unlock with all possible methods).
Prior to installation, ensure that all wiring is secure. Each unit should
be checked annually for:
Impaired Operation
Units are designed to operate under adverse environmental conditions.
Under normal circumstances, they will function properly regardless
of outside conditions. However, units do not have secondary power
sources and cannot function without direct continuous power. If a
unit is damaged by natural causes or deliberate vandalism, it may not
function properly depending on the level of damage.
