May be a single-cell or dual-cell Lithium-Ion battery. Figure 2: Hard Hat Components Battery Charging Station. Can charge up to 4 battery packs simultaneously and is supplied separately. Additional Battery Packs. May be procured through Guardhat to allow for extended hard hat use.
USER INTERFACE Wearing the Hard Hat Before wearing the hard hat, loosen the suspension by turning the ratchet mechanism knob counterclockwise (see Figure 3). Put the hard hat on your head and tighten the suspension as necessary by turning the knob clockwise. Figure 3: Suspension Adjustment There are five aspects to the hat’s user interface. Buttons are pressed by the user in order to communicate, both with the Safety Control Center (SCC) and with other users.
The microphone allows the user to communicate directly with the SCC and/or other users as well as to capture audio to accompany a video recording. The camera is capable of capturing both still images and video, which are transmitted to the SCC. It also allows for video calling to show the Safety Operator what the user sees in real time. Buttons There are 7 buttons on the underside of the brim (see Figure 5) and 1 button on the top (see Figure 4).
Figure 5: Brim Buttons • Power Button. Used to turn the hard hat on (3 second press) and off (5 second press). • Channel Button. Used to change the channel for communication using PTT. • Push-to-Talk (PTT). Used to communicate directly with all users tuned to the current channel. No dialing is required for this portable-radio style communication. • Repeat Button. Used to recall the last event and replay the audio associated with it. • SOS Button.
The LEDs light up with various colors and frequencies depending on the event / message (see TABLE for a full list of LED indicators and the associated events). The visual indicator of the LEDs is a key communication method that responds to events triggered by the user, by the SCC, and by the hat / the software that powers it. These lights alert users even in situations where ambient noise is too high to accurately hear audio communication.
Figure 7: Neighbor LEDs Communication: Microphone, Speakers, & Camera The speakers allow communication to be extremely specific. While the same color might light up for multiple events, each audio alert is unique and can provide detailed notifications. Additionally, the SCC can communicate to users via the speakers and users can communicate with each-other using Push-to-Talk for CB-Style communication.

EVENTS Guardhat model HC-1 detects a number of safety-related conditions and communicates these conditions known as events to multiple recipients, including the SCC. Your company may choose to customize which events are detected as well as the priority ranking of each event. Event Audio is listed in English however, the audio can be configured to multiple languages depending upon the country and language of the users. The priority of each event is only relevant if multiple events happen simultaneously.
Evacuation An Evacuation Event occurs when an area is deemed unsafe or needs to be cleared of personnel for any reason. The evacuation area can include any part of the worksite, including the entire site. The SCC Operator draws a three-dimensional area in the web application to initiate an evacuation.
SOS An SOS Event occurs when a user is in danger and/or requires immediate assistance. In addition to the SCC Operator, nearby users will be notified of the SOS request and can find the user who initiated it by the flashing LEDs visible on the outside of the hat. Figure 11: SOS Event Item Description Event Initiated By User Reason for the Event Urgent help required Event LED Flashing Red SOS LED Flashing Red Neighbor EDs Event Audio (English) “SOS Initiated.” User Response Wait for help.
Fall Detection A Fall event is initiated when the hat detects a fall, indicated by a rapid drop in altitude greater than 4 feet. This setting can be customized depending upon the specifics of the worksite and situation. Item Description Event Initiated By Hat / Software Reason for the Event Fall detected (rapid drop in altitude greater than 4 ft). Event LED None Event Audio (English) “Fall detected.” User Response Wait for help. Contact SCC operator if no help needed.
Geofence Breach Geofences are defined by the SCC Operator and can be customized to allow specific personnel into the defined locations at specific times. A breach occurs when a user who is not permitted to be in the zone passes through the invisible barrier. The user will receive warnings about approaching the geofenced area before a breach occurs. Figure 12: Geofence Breach Event Item Description Event Initiated By Hat / Software Reason for the Event Unauthorized User has entered a geofenced zone.
Network Disconnect Event The hat may use one of many networks including Ultra-wideband, Wifi, LTE, & Bluetooth. If there is an interruption to the network that prevents the hat from connecting to it, the network disconnect event will notify the user. If the hat is equipped with a camera, video and still images can still be recorded during the disconnect but the files will not be transmitted to the SCC until the network connection is re-established.
Blackout Zone Event Blackout zones are defined by the SCC Operator. These are areas where no location data or media may be transmitted from the hat. Although defined by each worksite, blackout zones likely include restrooms, locker rooms, and other locations where privacy is expected. Figure 14: Blackout Zone Event Item Description Event Initiated By Hat / Software Reason for the Event Network signal lost Event LED Solid Amber Event LED Event Audio (English) User Response “No network connection.
Hat Not Worn Event When the hat is powered on but is not in use, it triggers the hat not worn event. This reminds a user to wear the hat if on the worksite or to power the hat down if it is not in use. Figure 15: Hat Not Worn Event Item Description Event Initiated By Hat / Software Reason for the Event Hard hat is powered on but is not being worn by a user. Event LEDs Flashing Amber Neighbor LEDs Event Audio (English) “Hat not worn.” User Response Wear hat or power off if not in use.
Elevated Noise Event Sensors in the hat respond to ambient noise over a set decibel level by providing a warning that the noise level is high enough to potentially cause hearing damage. This noise level can be customized for a worksite by the SCC Operator. Figure 16: Elevated Noise Event Item Description Event Initiated By Hat / Software Reason for the Event Ambient noise is at a level that may damage hearing. Event LEDs Flashing Red Event LED Event Audio (English) “Noise level high.
Low / High Temperature Event Sensors in the hat respond to ambient temperatures below and above set temperatures by providing a warning that the temperature is too cold or too hot. These minimum and maximum temperatures may be customized for a worksite by the SCC Operator. Figure 17: Low / High Temperature Event Item Description Event Initiated By Hat / Software Reason for the Event Temperature is detected to be lower or higher than a set limit.
Acceleration Event Sensors in the hat respond to acceleration over a set limit by providing a warning that the acceleration is high, indicating that a dangerous situation may be at hand. This maximum rate of acceleration may be customized for a worksite by the SCC Operator. Item Description Event Initiated By Hat / Software Reason for the Event Heightened acceleration detected. Event LEDs none Event Audio (English) “High acceleration detected.” User Response Seek help / report conditions to SCC.
Proximity Event A Proximity event is triggered when a user is approaching an object that has been tagged with a beacon, for example, dangerous and/or moving equipment. Figure 18: Proximity Event Item Description Event Initiated By Hat / Software / Beacon Reason for the Event Hat / User is close to a Beacon Event LEDs Flashing Red Event LED Event Audio (English) “Proximity Danger.” User Response Move away from the dangerous situation / location if possible to do so safely.
POWER & CONNECTIVITY The included battery is a dual-cell 4800 mAH Lithium Ion battery, which is suitable for an eight to 12-hour shift. Multiple batteries may be purchased separately in order to extend the hat’s working life before recharging. Installing and Removing the Battery Only a Guardhat battery may be used with this device. To install the battery, lower the battery pack into the compartment on the back of the hard hat and tighten the thumbscrew by turning it clockwise until it is finger-tight.
