Safety Summary
This safety summary relates to the ACCOLADE Miner Mesh Locator (MML). Follow all
precautions that appear here and throughout the guide Ignoring warnings could result in
death or serious injury. Ignoring cautions could result in minor or moderate injury,
damage to equipment or property, or loss of system effectiveness
A WARNINGS
a Do not turn on or use the MML within 8 feet of explosives or blasting
components. The MML’s transmitted waveform characteristics are short
duration (milliseconds/second) pulses, with a power level of one (1) watt or
less. The MML is classified as a low—power RF source, as defined by the
Institute of Makers of Explosives. Safety Library Publication No. 20.
I Do not replace the MML battery yourself. Only a qualified technician can
remove or replace the MML battery. The MML is approved for use with the
MM}! rechargeable battery assembly (part no. 1 101-0083, drawing number
SGL2.932t008PA), 3.6V.
- Charge the MML battery according to the manufacturer’s directions in fresh-
air locations onlyt
- Do not modify the MML or remove its cover, since a fire, electrical shock, or
breakdown could result.
RF Expos u re
The MML with its internal antenna complies with the Specific Absorption Rate (SAR)
RF exposure requirements set forth for body worn equipment under all operating modes.
The MML complies with the requirements specified in AN SI/IEEE Std. C95,l-l999 and
FCC 47 CFR 2.1093 for the Uncontrolled Exposure/General population environment. It
has been tested and evaluated in accordance with FCC OET Bulletin 65, Supplement C
Edition 01-01.

Audio Indicator
I The audio indicator indicates the state of the MML. See Table l.
Multi-purpose connector (MPC)
- The MPC serves as the interface point between the MML and other
hardware.
o The MPC provides contacts to:
U Charge battery.
I Update the operational sofiware.
Battery
I The battery pack is composed of three NiMH cells that supplies a
nominal 36 VDC with a capacity of 1.65 Ah up to 2.20 Ah.
. The MML constantly receives from the mesh and transmits its
status to the Mine Operation center (MOC) through the mesh
network. The MML can operate in excess of 16 hours, under any
and all conditions on a fully charged battery. The worse case
average current draw occurs during Networkelnitiated
Emergency Mode and was measured as 88 mA.
- Note that as with all battery-powered devices.
temperature and storage conditions can reduce battery
life. To maximize battery life, store in a cool place
(-20""C to 30°C (- 4°F to 86°F) with humidity from 40%
to 80%. Minimize exposure to high heat above 50°C
(122°F), Fully charge the battery prior to long-term
storage. When in long-term storage, recharge every three
months.
- The battery maximum output voltage may be as high as 4.2 V, and may
go as low as 3.0 V due to temperature and discharge.
A WARNING
- Do not replace the MML battery yourself Only a
qualified technician can remove or replace the
MML battery, The MML is approved for use with
the NiMH rechargeable battery assembly (part no.
1101-0083, drawing number SGL2,932.008PA),
3.6V, l.65 Ah.

3 - MML Operation
The MML is a tracking, mesh status and emergency status indication device. It
requires minimal user interaction. The MML goes into sleep mode when inserted
in its charging cradle and activates (tums ON) when removed from its charging
cradle. The user need not turn it ON and OFF with the ON/OFF button, although
he can if he chooses to, The LEDs and audio indicator convey the MML’s status,
as shown in Table 1‘
The MML is a transceiver and therefore, in addition to allowing the Mine
Operation Center (MOC) to track the MML, it provides valuable feedback to the
MML users
0 The MML indicates when it goes outside the ACCOLADE mesh
network. This tells users they are no longer being tracked and that they
can no longer declare an emergency
0 The MML indicates when an Emergency it has declared has been
received by the M00
0 The MML indicates when the MOC has cleared an Emergency.
Normal Mode
Normal Mode is defined as inside the ACCOLADE mesh network, with no
Emergency declared and the MML’s battery at greater than 10%.
Outside the Network Mode
This is entered when the MML does not receive the ACCOLADE mesh network
for greater than 1 minutes
Low Battery Mode
Low Battery Mode is defined as when the battery is less than 10 % charged, The
remaining operating time of the MML when the low battery indicator activates is
greater than two hours. The MML user should go above ground and recharge the
MML when this mode is entered.

Emergency Mode
Each MML has an individual Node H). The MML shall ignore all mesh network vorce
and data traffic except:
0 “All-call” messages from the MOC.
- Broadcast voice or text calls,
I Voice or text calls addressed to its individual Node D).
Emergency mode is entered by the MML or when the MML detects emergency traffic
directed to the entire mine (broadcast or “all-call”) or specifically directed to its node II).
MML Self-declared Local Emergency Mode
The MML user may initiate an emergency by pressing the emergency button for 2
seconds.
1. This shall cause the MML to send a broadcast emergency text message
“Emergency Declared” and enter Local Emergency Model
. Other MMLs receiving this message enter Network-Initiated
Emergency Mode.
' The MOC acknowledges by sending an Emergency Ack
message.
. If the initiating MML does not receive this
acknowledgement from the MOC within 5 seconds, the
intermittent buzzer will cease leaving just the flashing
red LED indication. In this state, the user may re-initiate
the emergency (in the hope of receiving an
acknowledgement) by pressing the emergency button for
two seconds. After the button has been held down for
two seconds, the MML shall continue as described in
step 1 (above). If the button is held for 4 seconds or
more, the MML shall continue as described in step 4
(below)
2. If the initiating MML receives the acknowledgement within 5 seconds, it
shall turn on the green LED and the buzzer. The buzzer shall turn off
after 5 seconds, The green LED shall remain on for a further 5 sees (10
seconds total) and then turn off, leavmg just the flashing red indication.
3‘ While the MML is in local emergency mode, the user may, at any time,
cancel the emergency by pressing the emergency button for 4 or more
seconds. In this case, the MML shall continue as described in step 4
(below).
4. If the user cancels the local emergency by pressing the emergency
button, the MML shall send a non-emergency broadcast text message
“Emergency Cancelled” to notify all other units and the MOC and then
revert to normal mode,

Network-Initiated Emergency Mode
When not in emergency mode, MML shall enter the Network-Initiated Emergency
Mode upon receipt of any of the following:
- Emergency broadcast voice from any source.
0 Emergency broadcast text from any source.
0 Any all-call communication from the MOCr
- When MML is in a Network-Initiated Emergency Mode, receipt of non-
emergency text or voice from the ID that initiated the emergency or from the
MOC causes the MML to revert to normal mode.
0 When MML is in a Network-Initiated Emergency Mode, the user may, at any
time, cancel the emergency by pressing the emergency button for 4 seconds.
In this event, the MML shall revert to normal mode.
I While in (local or network initiated) emergency mode, the MML shall ignore
all-call voice messages
0 Note: This is different from the MMR, which reverts to normal mode
after receiving all-call voice messages.

4 - Maintaining the MML
MML maintenance consists of charging the MML and replacing the battery.
Charging an MML
0 Charge the MML to full capacity before use in fresh-air locations only
(above ground) Fully charging takes less than 8 hours.
a Each full charge lasts 24 hours or more under nominal conditions.
0 Recharge each MML afler each miner finishes his shifi — whether it’s a
single shift (8 hours) or double shifi (16 hours). Do NOT give the MML
to another miner unless it has been recharged for at least 8 hours,
I Charge unused MMLs to capacity in a fresh-air location only, check
them once a quarter, and recharge as needed,
A WARNING
. Charge the MML battery according to the manufacturer‘s
directions in fresh—air locations only.
Replacing the MML’s battery
Have a qualified technican replace the battery afier 500 charging cycles
A WARNING
- Do not replace the MML battery yourself. Only a
qualified technician can remove or replace the
MML battery. The MML is approved for use with
the NiMH rechargeable battery assembly (part 110.
