Stability monitor
Leader SENTRY B1

Firefighter and USAR applications

Leader SENTRY laser allows the user to monitor the distance of the structure to be monitored during a fire, as well as during a rescue-clearance operation.

Accurate for optimal safety

Leader SENTRY detects a movement of 5 mm at a distance of 30 m. A telescopic sight can point accurately the unstable structure targeted.

Versatility

Multiple maximum movement thresholds (from 5 to 100 mm) can be selected. When a movement is sensed that exceeds the selected threshold, the sound alarm is triggered (98 dB).
It continuously monitors detected movements and displays changes on its screen 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 on its screen for real-time awareness.

Leader SENTRY can detect a 5 mm structure movement at a distance of 30 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 (98dB) when a structure movement, however small, is detected.

GENERAL CHARACTERISTICS

Primary function
Monitors movements of unstabilised and stabilised structures at distance (30m) = far safer
Configurations
Sentry B1 (1 laser beam with control box)
or 2 Sentry B1 can also be used together so that they can be autonomous and are not constrained by 20 m linkable cable in case user wants more distance between them.
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 5 mm to 100 mm.
Several thresholds (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 98 dB ensures alarm to be heard or OFF
Alarm option
Sentry proposes an out put source to plug a remote loud speaker
Flash light
2 blinking rythms: working signal or alarm triggering
Filters
Out short-duration interruptions of the beam passing through it (e.g. people, birds etc.) are filtered.
Environnement
Designed for external positioning during rescue response
Specialties
Avoid shiny surfaces or too bright and too dark surfaces
Laser efficiency (distance) decrease with high luminosity from sun
Does not work with smokes, rain or fog.
