1 Overview
The Bump cap Personal Alarm Device (PAD), model BC-PAD-2, is part of a complete HIT-NOT® Proximity Detection System from Frederick Energy Products. This device, worn by pedestrians, provides warnings to both individuals and to vehicle operators to alert them that the individual has entered too close to an operating piece of equipment and is in a dangerous situation. The Personal Alarm Device is worn by the pedestrian to alert them of impending danger. The Bump Cap PAD is one device that comprises of two parts: (1) a PAD Base Module which is mounted to the rear of the user’s headwear and (2) a Warning Module permanently connected to the Base Module by an electrical cable that clips onto the user’s headwear brim.
1.1 Theory of Operation
Functions of the Personal Alarm Device are:
· To sense the 73 kHz field generated around a vehicle or piece of machinery equipped with a Magnetic Field Generator (MFG).
· To echo a signal back to the Magnetic Field Generator to confirm signal recognition. · To transmit a 916.48 MHz RF signal to the Magnetic Field Generator. · Turn on its own alarm when the 73 kHz signal from the Magnetic Field Generator is
confirmed.
When a PAD is in close proximity to the MFG, the PAD will detect the 73 kHz magnetic field from the generator and analyze its field strength. When the 73 kHz field strength received by the PAD is above a certain threshold it will indicate that the distance of the Magnetic Field Generator is close enough to the PAD to signify a Warning or Danger condition. The PAD is calibrated to differentiate the magnetic field into two zones: Warning and Danger. The PAD will echo back to the Magnetic Field Generator with a 916.48 MHz transmission to confirm the signal recognition and then send the alert to the Magnetic Field Generator. The Magnetic Field Generator has its 916.48 MHz receiver ON when it is transmitting the 73 kHz field and is “listening” to receive any 916.48 MHz transmissions from a pedestrian with a PAD to indicate the individual is too close to the vehicle and warrants a warning or danger condition. When an alert condition has been confirmed between the PAD and Magnetic Field Generator, the PAD will activate its own alarm. The signal in the Warning Zone will activate an LED light and a sounder as a continuing series of 3 rapid flashes/beeps followed by an OFF period every three seconds. If the pedestrian is in the Danger Zone, a continuous alarm and LED will be activated.
1.2 Frequency of Operation
The Personal Alarm Device will receive on a frequency of 73 kHz and transmit on a frequency of
916.48 MHz.

2 Operation
2.1 Installation Information
The PAD is a two-part device that includes a Warning Module permanently connected to a Base Module via a flexible electronic cable. Ideally, the PAD Base Module attaches to the back of a Hard Hat (or Bump Cap) using Velcro and the Warning Module clips to the brim of the Hard Hat (or Bump Cap) using a built-in metal clip. The flexible electrical cable is routed around the side of the Hard Hat (or Bump Cap). An alternative mounting is to secure the Base Module in a pocket inside clothing or a safety vest and attach the Warning Module to clothing or safety vest near the chest where the user can better hear the audible alert and see the LED light. To function properly, the Base Module and the Warning Module must be separated by at least four inches when installed. THE PAD IS POWERED AT ALL TIMES EXCEPT WHEN ITS BATTERY IS BEING CHARGED.

2.1.1 Inoperability Warning
When a PAD battery voltage drops to approximately 3.5 Vdc or below while connected to a PAD, the PAD will signal a low battery condition. This alert is two rapid beeps of the sounder every 1.6 seconds. When the PAD determines the battery to have low voltage, the PAD will cease to give zone warnings and will give only a low battery alert. CAUTION: WHEN A LOW BATTERY IS SIGNALED, THAT PAD SHOULD NOT BE USED UNTIL ITS BATTERY IS RECHARGED.
2.2 Charging
The 3.7V Li-ion PAD battery is charged from a special charging cable provided with each PAD. The special charging cable has a USB male connector on one end and a special plug on the other end that magnetically attaches to the PAD. The charging cable provided with each PAD includes a 100-240 Vac Wall Adapter. The Wall Adapter provides an output current of 0.1 A at a voltage of 5 Vdc. A LED light on the PAD displays a solid Red light while the battery is charging and changes to solid Blue when the battery is fully charged. When the charging cable is disconnected, the sounder on the PAD will activate for approx. 2 seconds to indicate it is in proper working order.
The PAD should to be charged daily and connected to the charger over weekends and holidays.
2.3 Alerts
The Bump cap PAD is typically worn on a Hard Hat (or Bump Cap) or alternatively near the chest of the pedestrian. The PAD has an LED visual indicator and an 85-88 dBA (typical) sounder to alert the user. If the battery voltage in the PAD drops to approximately 3.5 Vdc the PAD will signal a low battery condition with two rapid beeps every 1.6 seconds. NOTE: THE PAD WILL CEASE TO GIVE WARNINGS TO THE WEARER WHILE SENDING THE LOW BATTERY ALERT.
2.4 Maintenance
The Lithium Ion Battery in the Personal Alarm Device has a finite life and eventually will need replacement. Battery life is based on the number of times recharged. There are no published data about the exact number of charges the battery can undergo before its life is over, but literature suggests it’s at least 300 charges. Batteries in the PAD are designed to be replaced by the user. Only use an approved, protected Lithium Ion replacement battery. Contact FEP for the approved replacement battery list.
A daily check of the LED and sounder is advised to verify the PAD is functioning. Any PAD can be shown to be working properly by an approaching truck with a generator and verify that a warning is given at the expected distance.

2.5 Adjustments
Factory settings of the Personal Alarm Device are expected to be stable and change very little with time. Adjustment capability of the PAD by the user is not available for field use.
2.6 Interferences
There are instances when the magnetic field generated from other sources such as an electrical panel, motorized machinery, large conductor cables etc. can generate intermittent alarm signals that are picked up by the Personal Alarm Device. The PAD is designed to be fairly sensitive to pick up the energy from the Magnetic Field Generator though it is also fairly selective. This sensitivity can cause the PAD to be triggered by some sources that are producing a strong magnetic frequency (that happen to fall within our guidelines) if the PAD is very close to the sources usually within a few inches.
If a user stands against a wall near a vehicle path, it is advisable that they do so with the PAD sticking furthest away from the wall as the wall may have interference sources such as high current cables or power panels etc. that may silence the PAD.
