and Battery Charging
WorkForce® model WF2 is a worker-worn motion-
sensing Man-Down Alarm that uses proprietary, ISM
license free, 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 motion sensing and also
radio trac for alarm messages. When the Auto-ON/OFF setting is
enabled, disconnecting the unit from the charger will activate the
WorkForce® and place it into Sensing Mode.
During activation, an operational signal of escalating audio tones
will be heard , the Power Indicator (at upper left) will begin to blink
approximately once per second, and the OLED display will turn
on. After a short series of splash screens, the OLED home page will
display the current status of the WorkForce including battery level,
unit ID, and Motion Sensing.
When WorkForce® is activated, its internal radio transmits signals
to other GRACE devices and equipment that are within RF range.
PRE-ALERT MODE: When a user remains motionless, a Pre-Alert
warning tone will begin to sound approximately 12 seconds
before going into Alarm Mode. When no motion is sensed for
approximately 78-83 seconds, WorkForce® begins an audible Pre-
Alert sound and the on-screen countdown Time to Alarm will be
highlighted. If motion is detected during Pre-Alert, WorkForce® will
reset into Sensing Mode.
ALARM MODE: There are three methods of activating Alarm Mode.
1) MOTION ALARM: After 90 to 95 seconds of no motion,
WorkForce® enters the Alarm Mode.
2) DISTRESS ALARM: WorkForce® user can activate Alarm
Mode at any time (from Sensing Mode or OFF Mode) by
pressing the Emergency Alarm Button.
3) FALL ALARM: After detecting a free fall of greater than 4
feet.
ALARM MODE: Is indicated by sounding a loud audio alarm
and the Alarm mode displayed on the screen. During alarm, an
emergency radio signal is transmitted to other GRACE devices and
equipment, alerting personnel of the alarm.
RESET the Alarm: Return WorkForce® to Sensing Mode by simulta-
neously 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 display screen
and LED activity ceases. When Auto-ON/OFF setting is enabled, con-
necting the unit to the charger will turn the WorkForce® OFF.
SYSTEM LOOP TEST: When in Sensing Mode, simultaneously press
and hold the UP and DOWN arrow buttons until a rapid tri-tone
and on-screen message conrms System Test Sent. During test,
the OLED display shows elapsed time and preset maximum time
for test to complete. A successful Loop Test is indicated by an
escalating tri-tone and display message “System Test Successful”.
If the Loop Test Acknowledge message is NOT received within the
congured timeframe, a de-escalating tri-tone will be heard and
“System Test Timeout” message displayed. NOTE: Use the Device
Settings option in WorkForce Conguration tool to enable/dis-
able this feature.
Operation of Special Features
EVACUATION ACKNOWLEDGMENT: If an Evacuate alarm message
is received by WorkForce®, it can be manually acknowledged by
simultaneously pressing both side buttons.
ABANDON ACKNOWLEDGMENT: If an Abandon alarm message
is received by 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® units or other GRACE devices. The
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 while sounding
a rapid ringing tone, and device info for the unit in alarm will be
displayed on the screen. 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 notications will be reactivated. This cycle will continue
until the telemetry unit in Alarm is reset or shut o. After the Alarm
Monitoring notication has been cleared, the last alarm received
can be recalled by scrolling through screens with the Select button.
NOTE: If an alarm has been received, the WorkForce® will not turn o
until the alarm has been cleared or reset.
MESSAGES RECEIVED: WorkForce® model WF2 is capable of
receiving canned and freeform messages sent by other WF2 pen-
dants, SC500, MS2000, Grace-Watch®, GMG, etc. When a message
is received: the red side LEDs ash in an alternating pattern, while
sounding a rapid ringing tone, and the message will be displayed
on the screen.
FALL DETECTION:
WorkForce® is capable of detecting a free fall of greater than 4 feet.
If a fall is detected, the device will enter the Fall Pre-Alert state for
15 seconds 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 automat-
ically 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 a Fall Pre-Alert message on
the display 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 a Fall Alarm message on the
display while sounding a loud audio alarm with a double beep.
Clear the Fall Alarm by simultaneously pressing both side buttons.
IMPORTANT NOTE: WorkForce® model WF2 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
Read Instructions Before Use
Always test WorkForce® prior to use

Grace Industries, Inc. 3
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g-
uration 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.
LOCATION: When the WorkForce® enters a Locator Beacon Coverage
Zone, the identity of the Locator Beacon will be shown on the Work-
Force® display screen. If a Locator Beacon is in a low battery condition,
the low battery indication will be displayed on the WorkForce® screen
in reverse contrast. The WorkForce®’s last three locations can be seen
by using the Left (Menu) button to scroll to the appropriate screen.
WorkForce® Mounting and Attachment
IMPORTANT NOTE: For WorkForce® to properly sense a falling
motion, the device must be securely attached to the user.
WorkForce® is equipped with a swivel-clip attachment designed
to clip onto a horizontal belt or strap. The optional high-strength
grip-clip is designed for secure attachment to personnel gear such
as to a vertical strap on the upper left or right shoulder with the

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.The WorkForce® 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.
