The Elpas Lone Worker Transmitter is a personal duress button device with optional
pull cord and fall detection capabilities. The LWT is designed for real-time monitoring
and tracking of staff members and visitors. The LoneWorker Fall Detect Transmitter is
designed both for seniors in assisted living facilities or work place staff members that
may be subject to attack or injury in high-risk environments.
Alarms may be triggered either by squeezing the two side buttons. In the Fall Detect
version, when worn on a belt, a short rip cord may be attached to a belt loop so that
an alarm is transmitted when the device is pulled off the belt.
Note: Users can also wear the LoneWorker Transmitter as a pendant using a lanyard. If you
choose to do so, make sure you use a lanyard for which, the force required to unlatch the tether
switch is less than the force required to open the clasp.
The pull mechanism is particularly useful for seniors with arthritis who have difficulties
pressing buttons.
The LoneWorker Fall Detect Transmitter also detects falls and alarms when tilted
horizontally. To prevent false alarms, the device indicates a pre-alarm by giving the
wearer a chance to cancel the alarm before it is transmitted by pressing on the front
cancel button.
(Actual product may vary from photo)
Button press or pull cord should be used as the primary means of calling for help even
after a fall. The fall detection is meant to alert in the event that the victim falls
unconscious and may not trigger if not sufficiently horizontal.
LWT based help call systems may be monitored by Elpas ELC controllers and/or by
Eiris Software. Elpas Low Frequency Beacons or IR readers may be used to provide
room level indoor location.
Outputs on all Elpas network devices may be used to drive sirens, strobe lights or PA
systems. Alerts may be sent to various handheld devices such as DECT handsets
using Eiris DECT interfaces or to IOS or Android smartphones using EirisGo apps.
Calls may be cleared by exposing the LWT to a responder’s handheld LF beacon
requiring that staff arrive at the location of the caller.
The same Elpas infrastructure used for the duress solution may also be leveraged for
Access control, Asset tracking, Attendance and intrusion alarming making Elpas one
of the most competitive comprehensive solutions available today.

Initial Activation & Software Enrollment
The Lone Worker Transmitter is shipped from the factory in
Sleep Mode to conserve battery power during transit.
1. Prior to initial usage, remove the Activation Label and then
press, simultaneously, both of the emergency call push buttons
for at least 7 seconds.
This action Awakens the Transmitter from Sleep Mode and also
enrolls its unique factory installed ID Number (a six-digital
hexadecimal value) into the Host RTLS Application.
If the Enrollment process is successful, the Red LED
Status Indicator of the transmitter lights up for 3 seconds.
(Refer to your Eiris Configuration Guides for additional details.)
Battery Replacement
1. Temporarily suspend usage of the Transmitter in the host
RTLS application.
2. Place the transmitter on its right side. Remove the 2 screws
that hold the battery cover to the body of the Transmitter
3. First time replacement: Utilize the pull tab (find it with the
Bat▼ mark engraved on the back) to slide the battery out of
the Transmitter.
Future replacements: In the absence of the pull tab,
remove the cover from the other side, and use a plastic
instrument to slide the battery out.
Dispose of the used battery in accordance with local
regulations.
CAUTION! After removing the battery please wait at
least 30 seconds before installing the replacement battery
so as to not cause damage to the tag or to negatively affect
the tag’s operational performance.
4. Slide the new battery into the transmitter.
IMPORTANT! Ensure that the positive (+) side of the
battery faces up.
5. Close the side-cover(s) such that the screw holes are
correctly aligned. Tighten the 2 screws snugly into place. Do
not over-tighten as this may strip the case threads.
6. Reactivate the Transmitter in the Host RTLS Application.
Safety Issues
It is the responsibility of the system installer to ensure that the
appropriate staff members are suitably trained in the usage and
maintenance of the Lone Worker Transmitter.
Additionally, Supervisory Alerts should be configured in the Host
RTLS Application to notify staff members that the detection
Transmitter is:
In a low battery condition, or
Not properly transmitting location and status data.
Note: The above configured Supervisory Alerts should be triggered
periodically to ensure system integrity.
Alert Testing
When you press either the left or the right emergency call pushbutton individually, you trigger the Lone Worker Transmitter to emit
a Test Alert Message for the host RTLS application to confirm that
the unit is functioning properly.
