Stability monitor
Leader SENTRY B2

Firefighter and USAR applications

Leader SENTRY WIRELESS laser allows the rescuer to monitor risky unstable structures during fire or rescue first responses, like heavy rescue road accident, trench rescue, land slide, building collapse, rescue-clearance operation, etc…

Wireless connection & Multiple monitoring

2 lasers are connected wirelessly for a simultaneous monitoring at 100m distance. As an example, 2 sides of an unstable building are monitored for 2D monitoring which bring safety to rescue teams working around or inside the structure.
Wireless provides ability to manage one laser from the other one at 100m distance.
A wireless remote control (option) can be used for even easier management from the field.

Accurate for optimal safety

The Leader SENTRY WIRELESS detects a movement of 1 mm at a distance of 50 m. A telescopic sight accurately helps targeting the unstable object that must be secured.

Versatility

Multiple maximum movement thresholds (from 2 to 100 mm) can be selected. When a movement is sensed that exceeds the selected threshold, the sound alarm is triggered (105 dB) together with powerful 360° flashlights.
It continuously monitors detected movements and displays changes for real-time awareness.

PRODUCT CHARACTERISTICS

Leader SENTRY is a stability monitor that detects the structural movements of an unstable building. Its laser continuously monitors detected movements and displays changes for real-time awareness.

Leader SENTRY can detect a 1 mm structure movement at a distance of 50 m! A telescopic sight helps to point the laser accurately at the targeted unstable structure.

It allows firefighters and USAR teams to be alerted by a visual and audio alarm (105dB) when a structure movement, however small, is detected.

GENERAL CHARACTERISTICS

Primary function
Monitors movements of unstabilised and stabilised structures at distance (50m) = far safer
Configurations
Sentry Double (2 laser beams wireless connected)
Risk during implementation
None as it is done in a chosen safe area and before any risk is taken, monitoring larger structurers and larger areas of work, thus protecting larger numbers of people
Technology
Telemeter laser beam
Monitoring method
Monitors and detects movements from 2 mm to 100 mm.
Several thresholds (2, 5, 10, 20, 40, 70, 100 mm)
Live monitoring
Sentry displays distance to target(s) in real time for movement evaluation allowing to choose relevant threshold
Unit calibration in field
None
Alarm
1 audible alarm level at 105 dB ensures alarm to be heard or OFF or Mute
Alarm option
Sentry proposes an out put source to plug a remote loud speaker
Flash light
3 powerful LEDs for an about 360° visibility that give working signal or visual alarm
Filters
Short-duration interruptions of the beam passing through it (e.g. people, birds etc.) are filtered.
Environnement
Designed for external positioning during fire and rescue responses
Specialties
Lasers are wireless connected giving them ability to manage one laser from the other one at 100m distance. An optional wireless remote control can also be paired allowing easy management from the rubble pile.
