Overview
The Check Out Station (COS), model #1370755, is an auxiliary component for the iWAREHOUSE Field Sense System. This device, built by Frederick Energy Products, performs a functional test of an iWAREHOUSE Personal Alarm Device (PAD), model # 1329196. The mechanical geometry of the COS model # 1370755 is specifically designed to test PAD model # 1329196. This PAD is comprised of a Base Module and a Warning Module connected to the Base Module via a flexible cable. Thus, the COS design includes slots that exactly fit the PAD Base Module geometry and includes a slot to exactly fit the Warning Module geometry.
Theory of Operation
The COS contains three miniature magnetic field generator elements that create
small magnetic fields for a PAD to sense and respond to. The COS evaluates the
interaction with a PAD to verify that the PAD properly detects and responds to
the COS magnetic fields. It also tests and verifies that a PAD has a proper
LED and sounder response to the magnetic field.
Functions of the Check-Out Station are:
- To generate small 73 kHz magnetic fields.
- To receive 916.48 MHz RF response signals from a PAD.
- To measure the output sound level from a PAD Sounder when the PAD responds to the COS magnetic fields.
- To detect LED output from a PAD Sounder when the PAD responds to the COS magnetic fields.
- To turn on a PASS indicator light if the PAD passes all functional tests or turn on a FAIL indicator light if any functional test is not successfully passed.
Each of the above functions is performed sequentially to test each PAD function.
Frequency of Operation
The Check Out Station will generate a pulsing magnetic field on a frequency of 73 kHz and receive on a frequency of 916.48 MHz.www.hitnot.com
FCC/IC Information
The FCC ID for the Check-Out Station QUI-FS-ICOS. This device complies with Part 15 of the FCC Rules. Operation is subject to the following conditions:
- This device may not cause harmful interference.
- This device must accept any interference received including interference that may cause undesired operation.
Any intentional or unintentional changes or modifications to the configuration
of the Personal Alarm Device, not expressly approved by Frederick Energy
Products LLC, could void the user’s authority to operate the equipment.
Note: This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
–Reorient or relocate the receiving antenna.
–Increase the separation between the equipment and receiver.
–Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
–Consult the dealer or an experienced radio/TV technician for help.
The required notices are specified in the RSS documents (including RSS-Gen)
applicable to the equipment model. These notices are required to be shown in a
conspicuous location in the user manual for the equipment or to be displayed
on the equipment model. If more than one notice is required, the equipment
model(s) to which each notice pertains should be identified. Suppliers of
radio apparatus shall provide notices and user information in both English and
French.
This device complies with Industry Canada license-exempt RSS standards (s).
Operation is subject to the following two conditions:
- this device may not cause interference, and
- this device must accept any interference, including interference that may cause undesired operation of the device.
Operation
Installation Information
The Check Out Station can be placed on any table or desk near a 110-240 VAC
electrical source. However, it is best located near the place PAD batteries
are being charged, and thus, convenient for conducting PAD tests when PADs are
removed from the charger and being readied for use. Another good location is
at entrance points to areas where PADs must be worn to protect from moving
vehicles. The COS is activated as soon as it is connected to a 110-240 VAC
power source via a 12 VDC Wall Wart Power Converter.
Inoperability Warning
The Check Out Station has no specific warnings for its own inoperability, but
there is a blue LED on top of the unit that should be illuminated when the
unit is powered on.
PAD Testing Operation
A PAD functional test is initiated by inserting an iWAREHOUSE PAD model
1329196 into the appropriate slots in the COS using the following sequence:
- Insert the PAD Warning Module into its designated slot. (see figure on the right) The Warning Module must be oriented so that the metal clip on the Warning Module fits into a pocket provided in the slot.
- Insert the PAD Base Module into its slot with the Warning Module cable oriented as shown in the figure on the right. A microswitch installed in the Base Module slot is activated when the Base Module is inserted and immediately begins a PAD test operation.
Note: If Step 2 is performed before Step 1, the COS detects that the Warning Module is missing and turns on both PASS and FAIL lights. If this occurs, remove the Base Module and reinstall the Warning Module and Base Module in the correct sequence.
When a PAD test is initiated at the end of Step 2 above, the COS automatically and sequentially performs the following tests on a PAD.
- During the first 2 seconds, the COS checks whether a PAD is issuing a low battery voltage alert (2 rapid beeps of the sounder every 1.6 seconds). If a PAD is issuing a low battery alert, the COS will simultaneously illuminate both the PASS and FAIL lights. If this occurs, remove the PAD and charge the PAD battery.
- The COS checks the operational status of each of the three magnetic field sensing elements inside the PAD. This step is performed for each of the three sensing elements in the PAD by sequentially energizing small 73 kHz magnetic field generators inside the COS close to each PAD sensing element. If a PAD properly senses the small magnetic field, (1) the PAD transmits a 916.48 MHz RF signal and (2) the PAD turns ON the sounder and LED on its own Warning Module. Thus, proper operation of a sensing element is verified by the COS receiving the 916.48 MHz RF signal and the COS microphone and light meter sensing the sound and light from the PAD Warning Module. The COS microphone and light meter are calibrated to verify that acceptable levels are present. If a check is failed at any sequential test of the PAD, the COS FAIL light is illuminated and testing stops. When all tests are successfully completed, the COS PASS light is illuminated. Note that a PASS or FAIL light illumination stays ON until the PAD is removed from the COS.
Charging
The Check Out Station plugs into a 110-240 VAC outlet via its Wall Wart Power Converter.
Alerts
The only alerts issued by the Check-Out Station is the PASS and FAIL lights illuminated during PAD testing.
Maintenance
The Check Out Station should be regularly cleaned to reduce the buildup of dust and dirt. There is a blue power-LED visible on the COS housing to verify that the COS is receiving electrical power.
Adjustments
Factory settings of the Personal Alarm Device are expected to be stable and change very little with time.
Interferences
The Check Out Station should not be used in a location with high electromagnetic interference (EMI) because the EMI can prevent a PAD from properly detecting the magnetic field pulses from the COS.
