Product Description
The Elpas Wi-Fi Man Down Tag is a personal duress button device with optional pull cord
and fall detection capabilities and is designed for real-time monitoring and tracking of staff
members and visitors. This tag is designed for both seniors in assisted living facilities or
workplace staff members that may be subject to attack or injury in high-risk environments.
Alerts may be triggered either by squeezing the two side buttons. When worn on a belt, a
short rip cord may be attached to a belt loop so that an alert is transmitted
when the cord is pulled.
Note: Users can also wear the Elpas Wi-Fi Man Down Tag 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 Elpas Wi-Fi Man Down tag detects falls and alarms when
tilted horizontally. To prevent false alarms, the device indicates a pre-alarm
by beeping and vibrating giving the wearer a chance to cancel the alarm
before it is transmitted by pressing on the front cancel button.
(Actual products may vary from photo)
Button press or pull cord (pull cord is present only in Fall detect version) 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.
Elpas Man Down Tags may be monitored by Elpas local controllers and/or by CenTrak
Omni Software. Elpas Low Frequency Beacons or IR readers may be used to provide
room level indoor location.
Note: Users who do not require it, can disable the IR functionality to prolong battery life. See page 3.
Outputs on all Elpas network devices can be used to drive sirens, strobe lights or PA
systems. Alerts may be sent to various handheld devices such as DECT handsets using
Omni DECT interfaces or to IOS or Android smartphones using the Omni Go app.
Calls may be cleared by exposing the Elpas Wi-Fi Man Down Tag to a responder’s
handheld LF beacon requiring that staff arrive at the location of the caller.
Warning: When IR location is needed, placing the Elpas Wi-Fi Man Down Tag in a pocket or covered area
will significantly reduce the IR range of the device. The Elpas Wi-Fi Man Down Tag should only
be worn on the outside of the user’s clothing.

Initial Activation & Software Enrollment
The Elpas Wi-Fi Man Down Tag is shipped from the factory in
Sleep Mode to conserve battery power during transit.
1. Prior to initial usage, remove the Activation Label and
simultaneously press, both of the emergency call push buttons
for at least 7 seconds.
This action Awakens Elpas Wi-Fi Man Down Tag 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.
Battery Replacement
CAUTION! Risk of explosion if battery is replaced an in
type. Dispose of used batteries according to the
manufacturer’s instructions.
1. Temporarily suspend usage of Elpas Wi-Fi Man Down Tag in
the host RTLS application.
2. Place Elpas Wi-Fi Man Down Tag on its right side. Remove
the 2 screws that hold the battery cover to the body.
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. Recommended
battery: CR2450 lithium battery.
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’s threads.
6. Reactivate the Transmitter in the Host RTLS Application.
Disabling/Enabling IR
By default, IR functionality is on.
1. Press button B1 (squeeze both side buttons) for five
seconds. The LED Flashes five times.
A single flash means IR is now on.
A double flash means IR is now off.
2. While the LED flashes, squeeze the side buttons again,
three short presses, to change from the current state. The
LED flashes again, as before, to indicate the new state.
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 Elpas Wi-Fi Man Down Tag.
Additionally, Supervisory Alerts should be configured in the Host
RTLS Application to notify staff members that Elpas Wi-Fi Man
Down Tag 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 push-
button individually, you trigger Elpas Wi-Fi Man Down Tag to emit a
Test Alert Message for the host RTLS application to confirm that the
unit is functioning properly.
CAUTION!
Before you remove the battery, press any
button for 4 seconds to discharge any residual voltage
from capacitors.

Cleaning & Disinfection Procedures
Use an appropriate antibacterial disinfectant such as Dispatch
®
Hospital Cleaner Disinfectant with Bleach from Caltech Industries
(http://www.caltechind.com) to clean the Lone Worker Transmitter.
Since ‘Cleaning Procedures’ may vary according to facility guidelines, thus the procedures given below are for illustrative purposes only:
Option 1 – Using Dispatch Disinfectant Spray
1. Lightly wet a disposable towel with Dispatch spray.
Do not saturate the towel
2. Wipe the outer surfaces of the sensor
3. Wipe the sensor with a dry disposable towel
4. Allow the sensor to air dry
5. Return the clean sensor to inventory or usage
6. Dispose of used towels per facility policies
Option 2 – Using Dispatch Disinfectant Towels
1. Open a new Dispatch pre-moistened towel
2. Wipe the outer surfaces of the sensor
3. Wipe the sensor with a dry disposable towel
4. Allow the sensor to air dry
5. Return the clean sensor to inventory or usage
6. Dispose of used towels per facility policies
Pull Switch Cleaning:
Frequent use of the pull switch may result in a buildup of dust on the mechanism. Dust buildup causes friction
which requires added force to pull and restore the switch. Should this occur,
clean the switch using a compressed air duster. Gently
spray on the pull switch, an
d use a brush (often included with the canister).
Alert Event Configuration in Omni
There are nine alert events relevant to the Lone Worker tag.
Lone Worker Fall Alarm (Fall Detect version only):When the
tag tilts and the pre-alert event is not cancelled within 15
seconds, the tag transmits the Lone Worker Fall alert which
indicates that the user has fallen and unable to function.
Lone Worker Front Button Press: In regular version, B2
down. In Fall Detect version, to cancel an alert event, the user
can press the button in the front of the tag. To cancel a Pre
Alarm event, the user can place the tag in the up-right position.
If the tag is repositioned, it transmits the Cancel (cancel the
pre-alert) event.
Lone Worker Panic: When under duress, the user can press
both of the side buttons, simultaneously, or pull the cord to
transmit a Lone Worker Panic alert.
Lone Worker Pull Cord Restore: When the user inserts the
cord back into place, the tag transmits a cancellation for the
pre-alert event.
Lone Worker Pre-Alert: When the tag tilts, it transmits a
Pre Alarm event. The pre-alert lasts for 15 seconds during
which, the user can cancel it.
Note that the Pre-Alarm and Fall event messages may
be disabled (and re-enabled) by pressing the front
button for approximately 10 seconds. The tag beeps
when the Fall function is disabled/enabled.
Lone Worker Single Side Button: To test the alerts, the
user can press either of the side buttons to transmit a Lone
Worker single-side button event.
Low Battery: When the battery of the tag runs low, it
transmits a low battery event.
Motion: When the tag is in motion, it transmits a Motion
event.
Stationary: When the tag is stationary, it transmits a
Stationary event.
