and Battery Charging
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 environ-
ments.
WorkForce®providesreal-timemotion-sensing,
including fall-detection, and contains an Emer-
gency 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 radio trac for alarm messages. The WorkForce® is also
sensing motion, if enabled. When Auto-ON/OFF setting is enabled, discon-
necting 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 approxi-
mately 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 going into Alarm
Mode. When no motion is sensed for approximately 78-83 seconds, Work-
Force® begins an audible Pre-Alert sound and an alternating Yellow LED
display in the Alarm Ring. If motion is detected during Pre-Alert, WorkForce®
will reset into Sensing Mode.
ALARM MODE: There are two 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 simultane-
ously 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.
WorkForce® 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 per-
sonnel 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 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-
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: When the Emergency Alarm Button is pressed, a radio
transmitted signal is sent from the WorkForce® to notify monitoring person-
nel that an emergency situation is present and rescue action is requested.
Alarm Mode: A WorkForce® is placed in Alarm Mode by pressing the
device’s Emergency Alarm Button. When this occurs, the device transmits
an emergency radio signal and emits a loud alarm audio tone.
Alarm Monitoring: Allows the user to monitor the status of other person-
nel working in the same general area when they are equipped with Work-
Force® 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 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.
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®.
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.
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.

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 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.
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.
