Overview - Setting Up Your Locker System
There are two types of systems available for the SM-344H RFID Lock:
• Standalone Fixed System: Numbered RFID wristbands are coded to operate on
a specific numbered locker. Guest is assigned a numbered locker and issued an
RFID card, wristband or key fob that opens/closes it.
• Software Managed System: Guest is issued an RFID card, wristband or key fob
that is assigned to an available locker using a central software suite.
No matter what kind of system you install, SM-344H RFID Locker Locks are easy to set
up and manage. Before you begin an installation, here are a few things to consider:
1. Locker Numbering: Each locker door should have a number on its outside that is
visible to the guest. This normally comes in the form of an engraved plastic or metal
number plate or handle that is affixed to the outside of the locker door.

2. Tag Numbering: For standalone fixed locks, 1-5 pcs of RFID tag (wristband, fob or
card) can be assigned to each lock. Most installations have the matching locker
number engraved into or written onto the tag. These can be purchased from
SYNOMETRIX at time of order.
Alternatively, a reusable plastic fob can be attached to the RFID tag with the locker
number on it, rendering it reusable should the wristband, card or fob break or be lost
by a guest.
Please consider how to handle broken straps on any wristbands that have been engraved.
Can you easily source a few new bands as replacements? Or is it better to buy the bands
blank and assign them to the locks when needed, attaching a number fob or writing the
locker number on the bands using a felt pen?
Not sure? Please contact us for a consultation, we are happy to help.
Two Part Set Up Before Installing the Locks onto the Doors
Part 1: Initialize the lock by setting the reset button
Load 3 AA alkaline batteries into the battery holder. Press the reset
button and hold it down until you hear a beep, see the red light flash and
hear a musical sound. The lock is now initialized, and all cards previously
programmed to the lock are deleted from memory.
Part 2: Set the Switches for Locking Mode and Allowed Number of Guest Cards
I. Switch A: Choose (1) auto-locking or (2) manual locking.
Auto-locking is the default setting. This allows the lock to open
when the guest card is scanned and locks automatically 5
seconds later. Manual locking means the lock opens and closes
when the guest card is scanned.
II. Switch B: Choose between (1) 5 pcs guest card per locker or
(2) 1 pc guest card per locker.
You can now install the lock, face plate and the latch stopper with the screws provided.

place and do not lose it.

in your facility or assigned to handle members and guests separately.

the music sounds and the red and green lights will flash. On the third scan a different
type of music sounds and the lights stop blinking. All master cards are now deleted

A user card (normally an RFID wristband or fob) is only used for locking or unlocking the
lock. Your choice of setting the locks to 1 user or 5 users depends on how you will use the
lockers in your facility. For example, is a locker randomly assigned to an individual who
visits your gym? Or does a family that has a membership get up to 5 pc of user cards?

and the red and green lights flash. During blinking, scan the card again and the music
sounds and the green light flashes, now scan a RFID card, the music sounds and the

cards can be programmed if the function is set to 5 pcs card mode.

sounds and the red and green lights will flash. During the blinking scan the master
