1INTRODUCTION
▪The Leader SENTRY Wireless movement monitor was designed to ensure the surveillance of unstable structures.
It provides additional security to teams involved in firefighting and emergency and rescue operations.
▪An eye-safe laser range finder is aimed at a potentially dangerous structure and continuously monitors the smallest
movements of it. The device can be used to monitor movements of any object or mass that may put people working
nearby in danger, such as unstable buildings, mudslides, avalanches, poorly balanced vehicles or any other similar
danger.
▪The laser range finder can be mounted on the supplied tripod or with the suction cup mount for attaching to a smooth
surface (vehicle body, window, etc.) and can detect movements up to a distance of 50 m depending on weather
conditions. A scope allows the user to aim the laser at the target structure. The distance between the range finder and the
target is indicated on the screen, as well as the movement measured in comparison to the selected detection threshold.
The device will trigger an alert when the selected threshold has been exceeded by 2 to 100 mm (0.007 to 0.33ft).
▪The laser range finder measures movements in the direction of the laser beam. The maximum accepted movement is
selected in increments. This allows the device to adapt to poor weather conditions or natural movements in the
structure. The variations are displayed on the screen until the threshold is reached. If the structure moves so as to
exceed the selected threshold, a powerful alarm (105 dB) is activated.
▪Two laser range finders can be used simultaneously, thereby allowing the user to monitor two different structures or
monitor the same structure from two axes of movement. The 2 lasers communicate via wireless connection.
The Leader SENTRY Wireless movement monitor is available in one or two-laser versions. An optional wireless
remote control is also available and can be connected to one or two lasers.
The Leader SENTRY Wireless movement monitor satisfies EC European recommendations:
Electromagnetic Fields, RoHS, WEEE.

2USAGE WARNINGS
Give each alarm the most attention possible.
Never assume that the reason for the alarm is accidental until that has been established definitively.
▪Ensure that the monitoring area is free of any unnecessary movements, (people, machines, etc.) in order to avoid false
movement detections.
▪In the case where it is no longer possible to measure the distance when a structure is under surveillance (in case of fog,
for example), the alarm will sound to alert the user.
▪The device is designed to filter out short-term obstructions to the laser beam (passing people, birds, etc.).
Longer lasting obstructions will trigger the alarm.
▪Fog, dust or intense light can influence the device's range. The user must take into account the environmental
conditions and adapt the distance so as to have accurate measurements.
▪When the temperature is very low (0°C (32°F) or lower), the batteries cannot be used. It is strongly recommended to
use an external power source.
▪Always make sure to use good-quality lithium, alkaline or rechargeable NiMH batteries.
Never use zinc batteries (zinc-carbon or zinc-chloride).
▪Do not use a mix of battery types.
▪When using the mains adapter outside, always protect it from rain and moisture.
▪Always test to see that the device is working correctly before any real use by verifying that the alarm works and the
flashes light up.
▪The scope is adjusted in a way to make the laser's red dot coincide with the cross-hair at 35 m (114.8ft).
Their alignment differs for distances shorter and longer than 35 m (114.8ft).
▪To avoid measurement errors, try as much as possible to position the laser beam perpendicular to the targeted surface.
Do not aim at dust-free glass, expanded polystyrene or surfaces that are similarly transparent.
▪When aiming at highly reflective surfaces, the laser beam can be diverted and measurement errors can occur.
▪The measurement time can increase when the surfaces are dark or non-reflective.
▪Wear a protective headset when approaching the laser after the alarm is triggered (105 dB).
▪Never look directly into the sun through the scope. That could cause eye injuries.

4.4 Filtering for unintentional passages
▪The device is designed to filter out short-term obstructions to the laser beam (passing people, birds, etc.).
Longer lasting obstructions will trigger the alarm. This function is only operational if a threshold has been selected.
The filtering zone is located between the laser and the target at two times less (-2 x) than the selected threshold.
Example with a 100 mm (0.33ft) threshold:
▪A movement in the filtered zone, such as a knock against the tripod, will trigger the alarm with a longer response time
from 1 to 2 sec., due to the filter. Conversely, a movement in the threshold zone will trigger the alarm immediately.
4.5 Adjustment and maintenance of the scope, laser pointer compared to the laser range
finder
The scope is used to view the target at a distance. From a certain distance and depending on the light
levels at the time, the red dots of the laser range finder and the laser pointer are no longer seen on
the target. The target cross-hair (cross) is then the only means for targeting.
▪Please note that the scope is adjusted in a way to make the laser range finder's red dot which appears on the target
coincide with the cross-hair at 35 m (114.8ft). Their alignment differs for distances above and below 35 m (114.8ft).
This is due to the distance between the laser and the scope mounted a few centimetres above the box.

and (target distance - 2x

4.6 Device usage
▪Identify the target to be monitored.
▪Ensure that the tripod is properly balanced and set up on solid ground. A ballast can be suspended from the tripod
to stabilise it. Adjust the height of the tripod if needed.
▪Aim the laser beam on the selected surface by using the scope.
The laser only functions on a non-transparent surface.
It's best to select a flat surface with a light grey colour.
▪Check the distance indicated on the display. To obtain the best performance, it is recommended to place the
laser less than 50 m (164ft) away from the structure. Try as much as possible to position the laser beam
perpendicular to the targeted surface.
▪When selecting the unit of measurement, it is possible to change from the metric to imperial system and vice
versa (see §5.1).
▪Select the detection threshold using the buttons ranging from 2 to 100 mm (0.1” to 4”).
▪Using the selected threshold, monitoring is activated after 2 seconds to avoid button pressing causing a
movement detected by the laser range finder. Check that the flashes are blinking:

▪It is recommended to test that the device works correctly before any real use. To test this, you only need to place
your hand in front of the laser beam to trigger the alarm. You only need to press any of the buttons on the
keyboard to stop the alarm.
Once the alarm has been stopped, monitoring must be restarted by selecting a threshold again.
The Leader SENTRY Wireless has 3 alarm rates:
1 to identify when a threshold has been exceeded.
1 to identify an error message Exxx (see § 7).
1 to signal low battery level.
NB: See Meaning of Visual & Audible Alarms (see § 5.2.1).
▪The Leader SENTRY Wireless is designed to detect movement in the axis of the laser range finder beam. To monitor
the two axes simultaneously, two devices can be used together and operated from the same control screen.
4.6.1 VIEW ALL function
Function accessible by pressing the button.
▪The VIEW ALL screen is only available if at least two devices are all connected.

4.6.2 Operation of networked devices
If acquiring a Sentry DOUBLE (2 lasers) or a SENTRY SINGLE (1 laser) with optional remote control, the laser
range finders and the remote control are paired together in the factory.
▪The laser range finder numbers (LA1 and LA2) are factory assigned and do not change.
▪In the event of separate acquisition, they can be paired or unpaired if needed based on the procedure (see § 5.5).
The lasers must be switched on one after the other so wireless connection takes place correctly.
NB: For a successful process, wait for the control screen to switch on the 2nd laser or remote control.
▪Once they are turned on, the devices indicate the wireless connection level.
If the wireless connection level does not appear, turn off the devices and restart.
▪Pressing for 5 seconds on deactivates the laser's radio communication so it exits the network and
makes it independent. The other devices no longer "see" it. Pressing on for 5 seconds resets the communication.
From any device connected to the network making the symbol appear it is possible to:
