Blast Movement Monitors (BMMs) are delivered to your site in a low power hibernation state. Each
BMM
must be switched on using the Activator before installation into a blast.
The BMM Activator provides the signal to turn a BMM on and to assign a delayed start-up time. It is
also determines if a BMM is transmitting.
The BMM Activator is a low power device, limiting its range to approximately 100 mm (3 in).
WARNING
All BMMs that are within range of the Activator will switch on
when the BMM On button is pressed. Ensure other BMMs are
well out of range (2-3 metres (6-10 ft)). Do not operate the
Activator anywhere near BMMs in storage.
Store BMMs in a separate location to the Activator.
The Activator works with Blast Anytime (BAT) or Normal BMMs.
The mode, BAT or Normal, is set at the BMT factory to match the BMM
type in your BMT package.
1.1 Blast Anytime
• BAT BMMs start transmitting upon sensing a blast. They also transmit for 15 minutes during
installation in a shot (when initially turned ON using the Activator) so you can take
measurements. BAT BMMs enter standby mode (stop transmitting) until sensing a blast. A
transmission delay can be set.
1.2 Normal
• Normal BMMs start transmitting once they are turned ON using the Activator until the internal
batteries run out of power. They also transmit for 15 minutes during installation in a shot
(when initially turned ON using the Activator) so you can take measurements. A transmission
delay can be set.
How does the delay work?
• For BAT BMMs, the delay counter starts upon sensing a blast. E.g. if a 4-hour delay is set,
the BMM will start transmitting 4 hours after blast detonation. Calculate the delay from blast
detonation.
• For Normal BMMs, the delay counter starts when the BMM is turned ON during installation.
Calculate the delay from installation time.
