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, including 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 Work-
Force® 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 mes-
sages. When 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 sec-
onds, 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) PANIC 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 Alarm Mode: Return WorkForce® to Sensing Mode by simul-
taneously 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, connecting the unit
to the charger will turn the WorkForce® OFF.
Operation of Special Features
EVACUATION ACKNOWLEDGMENT: If an Evacuate alarm message is
received by the WorkForce®, an EVACUATE message is displayed on screen
and the Evacuate LED indicator ashes Red. EVACUATION message 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 alternat-
ing pattern, 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 but-
tons 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.
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 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 simultane-
ously 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 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.
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 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 the WorkForce® to properly sense a falling
motion, the device must be securely attached to the user.

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 sec-
ond period of time where the WorkForce® will not receive a
other alarm message from that same device.
Alarm Message: A radio transmitted signal is sent from the
WorkForce® to notify monitoring personnel that an emergen-
cy 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® 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, 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.
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.
Canned Text Message: Canned Text Messages are pre-
programmed, text-based messages that can be sent from
one WorkForce®2 to another.
Dilution of Precision: A term used in satellite-gps navigation
to express the positioning accuracy of a GPS enabled device.
EVACUATE: Displayed on the screen when 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 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
Pre-Alert before an Alarm is activated.
GPS Status Icon: The GPS Status Icon appears on the Icon
Line of the Home Page when the GPS Location feature is ac-
tive. The icon changes based on the satellite x quality.
Home Page: The Home Page is the main page of the Work-
Force®2 that is displayed on startup and any time the device
is reset. Displayed information includes status icons, motion
sensing timer, device OEM and ID numbers, and the rm-
ware versions loaded on the device.
Icon Line: The top line of the home page displays the device
status icons.
Man-Down Alarm Mode: A WorkForce® or other GRACE
safety device enters an audible Alarm Mode when the Pre-
Alert Timer counts down to zero.
Monitoring Authority: The person(s) responsible for moni-
toring the status of the devices used by the various on-scene
personnel, usually from a centralized base location.
Motion Sensing Activation Icon: Appears on the Icon Line
of the Home Page when the Motion Sensing feature is
active. This icon changes as the device senses motion.
Motion-Sensing Timer: Indicates the seconds of lack-of-
motion required before the WorkForce® enters the Pre-Alert
mode.

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.
