1INTRODUCTION
This LEADER Sentry Building Stabilisation monitor is designed to be immediately operational and very simple to use.
Supplied as a self-contained system with its own power supply, the unit can be used almost anywhere.
The LEADER Sentry alerts Search & Rescue teams of imminent danger from structural collapse or the movement
of any mass which may harm or impede rescuers.
A harmless laser is sited on the potentially dangerous site or structure and the LEADER Sentry continually monitors
for any slight movement. In addition, it can be used to monitor any movement of mass or material which might slide and
endanger life during rescues involving mud slides, avalanches, unsafe vehicles or similar hazards.
Either mounted on a telescopic tripod or by using a high performing sucker pad for vehicular mounting, the LEADER
Sentry can detect a pre-selected movement accurately up to a distance of 30m (98ft). A telescopic sight allows the user
to precisely pinpoint the laser on the target area. The LEADER Sentry display will indicate the distance from the unit
to the target area and display the variance of movement up to the pre-selected alarm threshold.
The LEADER Sentry will alarm at pre-determined thresholds. These thresholds can be selected in increments between
5mm and 100mm or 0.2 inches to 4.0 inches.
The LEADER Sentry detects movement in the direction of the laser beam. Rescuers can select a maximum movement
tolerance in increments. This is useful when the operation is executed in adverse weather conditions or when there is
an acceptable tolerance of movement naturally occurring in the structure. The fluctuation is displayed on the unit until
it reaches the threshold. Should the structure move greater than the distance selected, it will immediately trigger a piercing
98dB audible alarm.
Two LEADER Sentry systems can be linked together via the same control system to allow two elevations to be
monitored simultaneously or two axis of the same structure.

OVERVIEW OF THE LEADER SENTRY
The LEADER Sentry comprises of a harmless laser telemeter with a high level of accuracy, allowing the measurement
of distances and movement. Both visual alarms and a powerful 98dB audible alarm will alarm users of excess movement
in the monitored area. A red flashing beacon provides a visual confirmation that the unit is activated and working.
The laser has a telescopic scope to enable accurate positioning of the laser beam.
(Magnification: 3x / 7x objective lens: 28mm).
DESCRIPTION DU TREPIED
DESCRIPTION OF THE ACCESSORIES
DESCRIPTION OF THE OPTIONS
The aluminum telescopic tripod: associated with a ball both axes will allow the user an
establishment and an optimum adjustment of the laser. The maximum adjustment height of
the tripod with the laser is about 2 meters. the tripod can be ballasted if used in strong
winds.
EXTERNAL POWER SUPPLY: 12V adaptor for
110/220V 50/60 Hz. Supplied with international adaptors
for the United Kingdom, Europe, the USA and Australia.
SUCTION CUP: The suction cup allows the laser to be attached to
all smooth surfaces, such as metal or glass. (Ref: D11.06.014)

3INSTRUCTIONS FOR ASSEMBLY AND USE
ASSEMBLY
▪Insert the extension neck securely into the tripod base. Extend the legs to the required height.
▪Attach the Laser / Tripod connector.
▪Secure the Laser onto the tripod.
▪Connect the Laser to the control panel using the orange cable. Attach one end of the orange cable to the rear of
the Laser. Connect the other end to the control panel connection marked “TARGET 1”.
▪Connect the black power cable to the control panel where marked “EXTERNAL POWER”.
▪Plug the cable directly into a cigarette lighter or similar for 12V power*. If mains power is to be used, then plug
the 12v connector into the mains power adaptor.
▪Ensure the protective cap is removed from the laser and the rifle scope.
*Note: The unit can be powered by AA batteries and it is good practice to ensure that batteries are installed.
However, it is recommended that battery power is used only if no other power source is available. The primary purpose
of battery power is in the event of mains power failure.
INSTALLATION
▪Identify the area of the structure or hazard which is likely to fall or move.
▪Ensure the tripod is balanced and on secure ground. Ballast can be slung below the tripod by using the S hook
provided.
▪Using the telescopic sight, pin point the RED laser dot on the chosen area.
The beam will not work if focused on Glass. Light-colored flat surface
is most suitable.
▪Check the distance on the Laser display screen. For accurate monitoring, ensure the distance is <30m (98ft).
Attempt to set the unit at right angles to the area to be monitored and focused on a flat surface.
▪Choose the type of measurement: To switch between metric or imperial measuring modes, switch off the device.
At switch on, press and hold the “5mm” button and the “ON/OFF”switch simultaneously.
Hold for a minimum of 5 seconds and then release.
▪Select the alarm threshold by pressing the button adjacent to each measurement 5mm to 100 mm. (0.2in. to 4in.)
▪The alarm is now activated. Ensure the red beacon on top of the laser is flashing. (5 second intervals)
▪It is good practice to test the unit prior to deployment by breaking the beam (place hand over lens)
to activate the alarm. The alarm is de-activated by pressing any of the alarm threshold buttons.
Warning: If the test is done, the threshold will need to be re-selected.
LEADER SENTRY has two alarms, one for identifying when a threshold is passed,
and the other for identifying an “E- “error message.

DESCRIPTION OF THE MENUS
The operation of the LEADER Sentry is displayed via several different screens to highlight the mode of operation.
LASER 1 AND LASER 2 MENUS
The menus for Laser 1 and Laser 2 are only displayed if the respective laser is connected. The menus are identical and display
the following:
Laser1 screen
Start-up screen
Laser2 screen
Two laser screen
Measured distance
Selected threshold
Laser selected
Battery level
Target motion

DUAL LASER MENU
If two Lasers are connected, the viewing screen will show both displays simultaneously. Each laser can be selected
individually and set to individual settings.
Follow the ASSEMBLY and INSTALLATION instructions for each laser, attaching the second Laser to TARGET 2
on the control panel. Set the monitoring threshold for Laser 1. Then select the threshold for Laser 2.
The LEADER sentry is designed to detect forward and backward movement in the direction it is pointing. To allow
2 dimensional monitoring, two LEADER Sentry detection systems can work in tandem from a single control box.
FILTERING OUT OF BRIEF INTERRUPTIONS
The apparatus is designed to filter out short-duration interruptions of the beam, e.g. people, birds etc. passing
through it. Longer interruptions will trigger the alarm. This function is operational only if a threshold is selected.
The filter zone is between the laser and the target –2 x the selected threshold.
Example with a threshold of 100 mm:
0mm
1000mm
800mm
900mm
1100mm
1200mm

4CONSIDERATIONS FOR USE
TREAT ALL ALARMS SERIOUSLY. NEVER ASSUME THEM TO BE
ACCIDENTALLY ACTIVATED UNTIL THE CAUSE IS ASCERTAINED
▪Ensure the area in the focal direction of the laser is cordoned off from all but essential personnel, to avoid false alarms
being activated.
▪If the LEADER Sentry is in monitoring mode (a threshold is selected) and the distance measurement is no longer
possible (Due to fog for example), the alarm will go off to warn the user.
▪The unit is designed to filter out minimal breaks of the beam by unavoidable actions. (Birds, People crossing).
Longer breaks caused by vehicles etc… will activate the alarm.
▪Airborne particles mist or high ambient light may affect the measurement range. The user should pay attention to
the weather and adapt the distance accordingly to get accurate measurements.
▪When the temperature is very low (0°C or below), batteries may not be usable. It is highly recommended to use an
external power supply when the weather is cold.
▪Always use good quality lithium, alkaline or NiMH batteries.
Never use zinc-carbon or zinc-chloride batteries. Always ensure battery polarity is correct.
▪Always use same battery type.
▪Always apply care if using the mains adapter outdoors. Protect it from rain.
▪Always ensure a pre check of functionality is done before deploying the system. Ensure the alarm is working and
the red beacon is flashing.
▪The sight scope is adjusted so that the laser dot is aligned with the crosshair at 65ft. Be aware fluctuation will occur
slightly outside this distance.
▪To avoid errors of measurement, do not aim laser at dust-free glass, expanded ploystyrene surfaces of a similar level
of transparency.
▪In the event of aiming the laser at trongly reflective surfaces, the laser beam can be deviated and errors of
measurement can occur.
▪The amount of time required to take a measurement can increase when surfaces are dark and non-reflective.
