1 INTRODUCTION

Blast Movement Monitors (BMM®s) are delivered to site with the transmitter in a low power

hibernation state. The BMM® transmitter must be switched on before installation into the

blast.

The BMM® can only be switched on by a specially coded signal which eliminates accidental

activation. The BMM Activator (Activator) is a remote control device that provides the signal

to turn a BMM® on and to also assign a delayed start-up time if required. It is also useful to

quickly determine if a BMM® is transmitting.

The signal from the Activator is low power to limit its range to approximately 0.5 m. This is to

control which BMM®s are switched on.

WARNING All BMM®s that are within range of the Activator will

switch on when the BMM On button is pressed. Ensure
other BMM®s are well out of range (several metres to be
certain) of the BMM® to be turned on or programmed. Do
not play with the Activator anywhere near BMM®s.
Store BMM®s in a separate location to the Activator

2 USING THE BMM ACTIVATOR

2.1 Hardware

The Activator consists of a tough ABS plastic case with a

sealed low-profile keypad. The battery compartment can

be accessed by pressing and sliding a section at the back
of the case. Use a good quality 9 V alkaline or

rechargeable Nickel Metal Hydride (NiMH) battery.

The BMM® System kit is supplied with an Aquapak. It is

a transparent case that is 100% waterproof when closed. It

has a cord for hanging around the user’s neck, which

frees up hands for other tasks and eliminates the chance
of dropping the Activator into a blast hole.

 It is strongly advised that the Activator be placed inside the supplied

Aquapak and hung around the user’s neck.

2.2 Quick Start

 Turn the Activator on by pressing the

Power button ❶. The digital display

❹ will quickly show the battery

voltage, and then show “00”. Once

less than 8.5, it is close to flat so have
a spare battery available.

 Press the yellow 1 or 10 button ❸ to

select the desired start-up delay time
in multiples of 4 hours up to a

maximum of 36 hours. The display
❹ shows the actual delay in hours.

 Position the Activator close to the

BMM® to be switched on (within
100 mm), and press the green BMM

On button ❷ briefly – the green

(transmit) LEDs ❺ will illuminate briefly. Activation is more reliable if the Activator is

pointing down at the BMM® (approx. 45) as shown in the photo in Section 2.1.

 If the transmitter switches on, the red (receive) LEDs ❻ will illuminate and an audible

tone will be generated at regular intervals (beep, beep, beep, beep…).

 Keep the Activator within range of the BMM

®

for at least ten seconds, to make sure the

BMM® continues to transmit. As a final check to make sure the BMM® is still

transmitting, move the Activator out of range of the BMM® and then back within

range.

 If the BMM

®

does not turn on, the respective transmit and receive aerials may be

unfavourably orientated, so move the Activator around the BMM® by 90° and try

again.

WARNING The BMM® cannot be switched off once activated

 In the future, the BMMs will be able to be assigned an ID code that

will make each one uniquely identifiable in a blast. The Type 5
Activator has been designed with this feature but it is not enabled at

this time.

2.3 Test Button

 The Test function only confirms that the BMM

®

is functioning by
turning it on briefly. It is not necessary to use this during normal use

and it is best to avoid using this function onsite.

If Test Mode has to be used to confirm a BMM® is functioning, position the activator as
previously described and press the grey Test button ❼ (the display ❹ can be any number).

The BMM® will then transmit for about five seconds and then turn off, ready to be switched

on normally.

2.4 Delayed Start-up

The BMM® transmits at constant power for about 10 – 12 hours so to accurately calculate the

depth of the BMM®s after the blast, they must be located within this period. The BMM® will

continue to transmit for about 24 hours beyond this time (total ~36 hrs) but the signal will

slowly decrease and eventually switch off. If the BMM® is located after the initial 10 hr period,

its horizontal location will be accurate but not its depth. The delayed start-up feature was

specifically designed for mines that could not access the muckpile immediately after blasting

due to light and/or safety reasons. It can also be used to install the BMM®s well before the

blast for operational reasons.

Once activated with a delayed start-up, the BMM® with transmit for approximately 15

minutes before switching off and sleeping for the requested period. At the end of the delay

period, it will transmit normally until the battery goes flat – just as it does with zero delay.

Refer to the “Monitoring Procedure Manual” for more information about how the delayed
start may be used.

Delays can be set in multiples of 4 hours, up to 36 hours. The displayed number is the actual

delay in hours, which is different to the old Type 4 Activator.

WARNING Once a BMM® is activated for delayed start-up it cannot

be changed. That is, it cannot be switched off nor be made
to switch on earlier or later.

2.5 Miscellaneous

The BMM Activator is also useful to quickly determine if a BMM® is transmitting since the red
receive LED ❺ will illuminate intermittently with sound whenever a BMM® signal is

detected.

3 TROUBLESHOOTING

Fault

Solution

The Activator won’t turn on

 Check the status of the battery and replace as necessary.

The display turns off during

operation

Low battery – replace

BMM® won’t turn on

 Change proximity of Activator and transmitter and try

again…and again.

 Confirm that the green button is depressed until the transmit

LEDs flash.

 Install an appropriate fresh battery. The transmit power may be

below the required threshold.

 The BMM

®

transmitter may be faulty. Set it aside, mark it

appropriately and contact BMT.
