WorkForce® model WF1 is a worker-worn motion-
sensing Man-Down Alarm that uses independent, high
performance RF (radio-frequency) wireless signaling
to help protect workers in dangerous and hazardous
environments.
WorkForce® provides real-time motion-sensing, includ-
ing fall-detection, and contains an Emergency Alarm
Button to immediately transmit a distress alarm signal.
WorkForce® Alarm Monitoring (AM) version also
receives distress alarm signals from other workers
equipped with WorkForce® and alerts the user with
audible and visual indicators. Other emergency
signaling features of WorkForce® include Evacuate, PAR,
Roll-Call and optional Out-of-Range indication.
A complete worker safety system can be achieved
by using additional Grace monitoring products with
locating capabilities.

Operating Instructions
(90 seconds to Alarm used for example)
ACTIVATING WorkForce®: Simultaneously pressing both side
buttons turns the WorkForce® ON and activates Sensing Mode.
In Sensing Mode, the device is monitoring radio trac for alarm
messages. The WorkForce® is also sensing motion, if enabled.
When Auto-ON/OFF setting is enabled, disconnecting the unit from
the charger adapter will activate WorkForce® and put into Sensing
Mode.
During activation, an operational signal of escalating audio tones
will be heard and the Power Indicator (at upper left) will begin to
blink approximately once per second. A pair of Green LEDs in the
Alarm Ring will begin ashing in an alternating display to indicate
motion is being sensed.
When WorkForce® is activated, its internal radio transmits signals
to other GRACE devices and equipment.
PRE-ALERT MODE: When a user remains motionless, a Pre-Alert
warning will begin to sound approximately 12 seconds before go-
ing into Alarm Mode. When no motion is sensed for approximately
78-83 seconds, WorkForce® begins an audible Pre-Alert sound and
an alternating Yellow LED display in the Alarm Ring. If motion is de-
tected during Pre-Alert, WorkForce® will reset into Sensing Mode.
ALARM MODE: There are 2 methods of activating Alarm Mode.
1) MOTION ALARM: After 90 to 95 seconds of no motion,
WorkForce® enters the Alarm Mode.
2) PANIC ALARM: WorkForce® user can activate Alarm Mode at
any time (from Sensing Mode or OFF Mode) by pressing the
Emergency Alarm Button.
ALARM MODE: Is indicated by a rapid pulsing of Red LEDs in the
Alarm Ring while sounding a loud audio alarm. During alarm, an
emergency radio signal is transmitted to other GRACE devices and
equipment, alerting personnel that personnel may need assistance.
RESET Alarm Mode: Return WorkForce® to Sensing Mode by si-
multaneously pressing both side buttons.
OFF: When in Sensing Mode, turn OFF by simultaneously pressing
and holding both side buttons for approximately 3 seconds until
a series of de-escalating audio tones are heard and all LED activity
cease. When Auto-ON/OFF setting is enabled, connecting the unit to
the charger adapter will turn the WorkForce® OFF.
SYSTEM LOOP TEST: When in Sensing Mode, press and hold
top button until a rapid tri-tone conrms the device has sent
Loop Test Message and the countdown timer has started. A
successful Loop Test is indicated by an escalating tri-tone and
side LEDs 4-1 blinking yellow in an upward sequence. If the
Loop Test Acknowledge message is NOT received within the
congured timeframe, a de-escalating tri-tone will be heard.
NOTE: see Device Settings, pg.10, to enable/disable this System
Loop Test feature.
Operation of Special Features
EVACUATION ACKNOWLEDGMENT: If an Evacuate message is
received by the WorkForce®, it can be manually acknowledged by
simultaneously pressing both side buttons.
ALARM MONITORING: Allows the user to monitor the status of
other personnel working in the same general area when they are
equipped with WorkForce® or other GRACE devices. WorkForce®
MUST be in the Sensing Mode to receive Alarm signals from other
Grace devices or equipment.When one device goes into Alarm and
an Alarm Monitoring WorkForce® receives the signal, the Red side
LEDs will ash in an alternating pattern. This alert can be cleared
for one minute by pressing both side buttons simultaneously. If
additional GRACE devices go into Alarm during this one-minute
period, the Alarm Monitoring LED display will be reactivated. This
cycle will continue until the telemetry unit in Alarm is reset or shut
o.
NOTE: If an alarm has been received, the WorkForce® will not turn o
until the alarm has been cleared or reset.
FALL DETECTION:
WorkForce® is capable of detecting a fall of greater than 4ft. If a fall
is detected, the device will enter the Fall Pre-Alert state for 15 sec-
onds to allow the user to reset the WorkForce® after a false trigger
or a fall that does not require assistance. Fall Pre-Alert can only be
reset by simultaneously pressing both side buttons. If the Fall Pre-
Alert is not reset within 15 seconds the device will automatically
enter the Fall Alarm mode. This will send out a Fall Detected Alarm
message to any compatible Grace monitoring equipment.
FALL PRE-ALERT MODE: Is indicated by alternating Yellow LED
display in the Alarm Ring, and a double beep after the Pre-Alert
tone. Fall Pre-Alert may be cleared by simultaneously pressing
both side buttons.
FALL ALARM MODE: Is indicated by rapid pulsing of the Red LED’s
in the Alarm Ring while sounding a loud audio alarm with a double
beep. Clear the Fall Alarm by simultaneously pressing both side
buttons.
IMPORTANT NOTE: WorkForce® model WF1 cannot detect every
possible type of ‘fall’-event and it is the user’s responsibility to
be trained to always push the Emergency Alarm button, if they
are able, following any type of ‘fall’-event.
SIGNAL-LOST/OUT-of-RANGE OPERATION:
Signal-Lost/Out-of-Range is an indication that the user is
beyond the eective signaling range of theWorkForce® and a Grace
monitoring device or unit, such as a Grace GMG or GFG Gateway,
MS2000, SMS or GraceWatch® system. This feature operates using
2 way signaling between the WorkForce and the monitoring unit
for the purpose of indicating to the user they may be out of the
eective signaling range of the system.
When this feature is enabled and under normal operation,
the user will receive notication they are in the eective
signaling range on the monitoring device within 30 seconds after
powering on the WorkForce®.
This feature can be enabled through the PC software
conguration tool. If this feature was not enabled, verify there is
a Grace monitoring device that present that supports Signal-Lost/
Out-of-Range notication and is congured to actively operate
with the WorkForce® units.
WorkForce® Mounting and Attachment
WorkForce® is equipped with a high-strength grip-clip designed
for secure attachment to personnel gear such as to a vertical strap
on the upper left or right shoulder with the sound port facing out,
or on the right or left hip area. The optional swivel-clip attachment

Grace Industries, Inc. 3
is designed to clip onto a horizontal belt or strap. However, the
ideal wearing position of WorkForce® is often best determined
by the end user for ease of access and operation.
IMPORTANT NOTE: For WorkForce® to properly sense a falling
motion, the device must be securely attached to the user.

Grace Industries, Inc. 6
Denition of Terms
Alarm Inhibit Timer: When WorkForce® receives an alarm message
from another GRACE Industries device and that alarm is cleared,
the Alarm Inhibit Timer provides a 30 second period of time where
the WorkForce® will not receive another alarm message from that
same device.
Alarm Message: A radio transmitted signal is sent from the Work-
Force® to notify monitoring personnel that an emergency situation
is present and rescue action is requested.
Alarm Mode: WorkForce® transmits an emergency radio signal
and emits a loud audio alarm tone when motion-sensing timer
has lapsed, fall-detection was recorded, or the emergency alarm
button is activated.
Alarm Monitoring: Allows the user to monitor the status of
other personnel working in the same general area when they are
equipped with WorkForce® or other GRACE devices. WorkForce®
MUST be in the Sensing Mode to receive Alarm signals from other
GRACE devices or equipment.
When one device goes into Alarm and an Alarm Monitoring
WorkForce® receives the signal, the Red side LEDs will ash in an
alternating pattern. This alert can be cleared for 30 seconds by
pressing both side buttons simultaneously. If additional GRACE
devices go into Alarm during this one-minute period, the Alarm
Monitoring LED display will be reactivated. This cycle will continue
until the unit in Alarm is reset or shut o.
NOTE: If an alarm has been received, the WorkForce® will not turn o
until the alarm has been cleared or reset.
Auto ON/OFF: When this setting is enabled, WorkForce® is turned
On and O by disconnecting or connecting the device into the
Charger Adapter.
Dilution of Precision: A term used in satellite-gps navigation to
express the positioning accuracy of a GPS enabled device.
EVACUATE: Evacuation signal received, indicating the user should
leave the area immediately.
Fall Detection: When in Sensing Mode, WorkForce® monitors the
user for a falling motion. Once a possible fall is detected, the unit
enters Fall Pre-Alert mode, alerting the user of a detected fall and
allowing time (< 15 seconds) to clear the detected fall before an
Alarm is activated.
Man-Down Alarm Mode: A WorkForce® or other GRACE safety
device enters Man-Down Alarm Mode when the Motion Sensing
Timer counts down to zero.
Monitoring Authority: The Monitoring Authority is the person/
people responsible for monitoring the status of the devices used
by the various on-scene personnel, usually from a centralized base
location.
PAR: Personnel Accountability Report is used to prompt the
person wearing the WorkForce® to acknowledge a PAR-request sig-
nal sent from a Grace-Watch® software monitoring system. This is
designed as a periodic check-in for the WorkForce® user providing
an indication of their well-being.
Radio Signal Propagation: Radio Signal Propagation is the
behavior radio waves exhibit when they are transmitted. Radio
Signal Propagation can be aected by structural, environmental,
and atmospheric conditions.
Resetting the Device: Simultaneously pressing the side buttons
resets the WorkForce®.
ROLL-CALL: Requires the use of a Grace-Watch® software
monitoring system and is designed to signal the WorkForce® user
of an escalated situation prompting the user to acknowledge their
safety status immediately.
Sensing Mode: When the WorkForce® is turned on, it is in Sensing
Mode. In Sensing Mode, the device is monitoring radio trac for
alarm messages. The WorkForce® is also sensing motion, if enabled.
Signal-Lost/Out-of-Range: Signal Lost is an indication that the
user is beyond the eective signaling range of the WorkForce® and
a Grace monitoring device or unit, such as a Grace GMG or GFG
Gateway, MS2000, SMS or GraceWatch® system
Unit ID: The Unit ID is the unique ID number assigned to the
WorkForce® device for the purpose of radio communication. It can
be viewed on the HID WorkForce® Conguration Tool.
Unit OEM: The Unit OEM is a number assigned to the WorkForce®
device and is similar to the Unit ID. The key dierence is the Unit
OEM is not a unique number to each device. In most applications
all of the WorkForce® devices will have the same OEM number;
from the factory, this number will usually be 9090.

User’s Manual info: Survey Mode,
WorkForce® Models WF1, WF2
1. The WorkForce® models WF1 and WF2 have a RF performance
Site-Survey test mode, further referred to as “Survey mode”,
whereby two WorkForce® units transmit and receive RF signals
between them providing an indication of anticipated RF signaling
performance when used in the environment that is being
surveyed. Important, PLEASE READ THIS ENTIRE SECTION ON THE
SURVEY MODE BEFORE ATTEMPTING TO PLACE A WorkForce®
UNIT IN TO SURVEY MODE.
a) The WorkForce® Survey mode is operational between two
model WF1 and/or model WF2 units and are not exclusive to
any model, thereby allowing two model WF1 units, two model
WF2 units or one of each (a model WF1 and a model WF2) to be
used in this Survey mode.
IMPORTANT NOTE: WorkForce® units placed in Survey mode
are not operational as a safety device.
b) While WorkForce® units are in the Survey mode, only
two WorkForce® units can be used at the same time for this
purpose, however on-going use of other Grace devices (includ-
ing WorkForce® units) can continue to operate, unaected by
the Survey mode testing.
c) The WorkForce® units, when placed in Survey mode
will assume a role of either roving-Primary or stationary-
Secondary, determined by which WorkForce® unit was put in
the Survey mode rst.TheWorkForce® unit powered on rst and
placed in Survey mode becomes the roving-Primary and the
second WorkForce® unit placed in Survey mode becomes the
stationary-Secondary.
d) The WorkForce® Survey test mode uses a method indicating
a successful RF transmit and receive from both units. When in
Survey mode, the WorkForce® does not Smart-signal® repeat
other RF signals from other Grace devices nor will they trans-
mit any polling signals. Typically, a WorkForce® model WF2 is
used as the Primary and a WorkForce® model WF1 is used as a
Secondary.
2. Placing the WorkForce® models WF1 and WF2 in to Survey
mode is done using this sequence:
IMPORTANT NOTE: WF1 can only enter the Survey mode
within the rst 15 seconds after powering on the WF1 unit.
(Lone Worker models are automatically powered On by
disconnecting the WorkForce® from the Charger Adapter.)
a. With the unit turned o, power on the WorkForce® unit by
pressing and releasing both side buttons simultaneously.
b. The WorkForce® model WF2 will use a menu and display to
enter Survey mode. After powering on the WF2, use the MENU
button to index the display showing message “Hold Select
3Sec for Setup Mode” and then press and hold the Select
button for 3+ seconds to enter Setup mode. Once in Setup
mode, press the MENU button to navigate to the“Radio Survey
Mode”menu item and enable the Survey mode by pressing the
SELECT button. To exit Survey mode, press and release both
side buttons (MENU and SELECT) and then again press and
hold the MENU and SELECT buttons simultaneously to power
o the unit.
c. The WorkForce® model WF1 is placed in Survey mode after
powering on by pressing and holding the unit’s SELECT button
(on the antenna side) and then the TOP button both for 3+ sec-
onds until a double-chirp beep tone sounds, indicating Survey
mode is entered. Note: Lone Worker models are automatically
powered On by disconnecting the WF1 from the Charger
Adapter.
d. Once the rst WorkForce® unit is placed in Survey mode,
THERE IS A REQUIRED 20+ SECOND WAITING PERIOD before
placing the second WorkForce® unit in to Survey mode. After
the 20+ second wait period, the rst WorkForce® unit begins
transmitting the Survey mode signals every 2 seconds indicat-
ed by the red LED transmit indicator and the audible two-tone
(high to low) chirp sound.
3. The rst WorkForce® unit placed in Survey mode will
automatically become the roving-Primary after 20+ seconds,
assuming there are no other WorkForce® units present that are
already in roving-Primary Survey mode. After the 20+ second
wait period, the second WorkForce® unit is to be powered on
and placed in Survey mode and will automatically become the
stationary-Secondary unit if it receives the Survey RF signal from
another WorkForce® already in roving-Primary Survey mode.
Once the WorkForce® units are successfully placed in their respec-
tive Survey modes, the roving-Primary WorkForce® unit will emit
two separate audible two-tone chirp sounds indicating successful
signaling between the roving-Primary and stationary-Secondary
WorkForce® units.
4. While the WorkForce® units are in Survey mode, the
recommended method used to survey an environment is to
place the stationary-Secondary WorkForce® unit at the physical
location that is intended to be the monitoring place for worker
alarms from all WorkForce® users, or the location that a Grace
Repeater would be placed, for large areas. Then a user is to carry
the roving-Primary WorkForce® unit to various locations in your
facility or environment while listening to the audible chirp
sounds, realizing that a change (not hearing the second two-tone
audible sound) will be noticed if the signaling links between the
WorkForce® units are not successful.
It is recommended that if available, a WorkForce® model WF2
is used as the roving-Primary unit as there are both audible
and visual (via OLED display) indications of successful signaling
performance including a resettable counter that shows the
number of attempts and successes of each set of test signals sent
and received every 2 seconds.
The Survey mode test signals are repeated by Grace telemetry
system Repeaters and other Grace xed monitoring equipment
including MS2000 series units.

Motion Timing Seconds: This setting controls how long the user and device can remain motionless before the Man Down Alarm is
activated. A Pre-Alert warning will begin to sound approximately 12 seconds before the Man-Down Alarm, indicating the WorkForce® is
closer to going into Alarm. Available timing (in seconds) includes: 0, 30, 60, 90, 120, 180, 300, 600, and 900. NOTE: Setting the timing to
zero (0) will DISABLE the motion sensing protection.
WARNING: Any motion sensing alarm time period longer than 90 seconds is potentially dangerous to the user of this product. The longer
the motion sensing time period is, the greater the risk of exposing the user to a delayed response to an incapacitated, distressed worker.
Alarm Button Delay Time: This value controls the number of milliseconds the alarm button must be held before an alarm is declared.
This timer is useful in eliminating accidental alarm triggers caused bumping the alarm button.
Note: This value is in milliseconds 1 second = 1000 milliseconds.
System Loop Test Timeout, in Minutes: Setting the value to zero (0) disables the System Loop Test feature. Selecting a
value of 1-15 sets the maximum number of minutes before System Loop Test failure is declared. System Loop Test sends a
message from the WorkForce® through your gateway to a monitoring platform. If the platform does not respond with an
Acknowledge of the loop test within the allotted time, the unit will trigger a System Test Timeout. (See page 2 for more
information on system loop tests).
