It is a bidirectional proximity warning system that detects the approach of heavy machinery and workers using "ultrasound" and "radio waves."
This is a bidirectional proximity warning system that detects the approach of heavy machinery and workers using "ultrasound" and "radio waves." The heavy machinery operator is alerted to danger through "sound" and "light," while the workers are notified through "vibration" and "sound." With one transmission unit, an unlimited number of workers' receivers can be added, and the system can operate with "up to 5 transmission units" at the same site.

basic information
1. Operating voltage: 24V 2. The heavy machinery side uses "sound" and "light," while the workers receive alerts through "vibration" and "sound." 3. Detection distance can be set in two stages (danger distance and warning distance), adjustable from 1m to 15m. 4. Furthermore, the warning distance setting can distinguish whether the heavy machinery is approaching, moving away, or stopped based on the vibration pattern of the receiver. 5. The workers' receivers can be expanded without limit. 6. A maximum of five transmission units can operate at the same site. 7. The receiver has a built-in battery and is charged using a dedicated charger.

<Transmission Unit> Main Specifications 1. Detection Distance (2-stage setting / Danger Distance and Warning Distance): Adjustable from 1m to 15m * Danger Distance: When a worker enters a very dangerous distance from heavy machinery * Warning Distance: When a worker enters a distance considered dangerous from heavy machinery ◎ Please set the Warning Distance longer than the Danger Distance * If the Warning Distance setting is shorter than the Danger Distance setting, the Danger Distance setting will take precedence, and the vibration and sound of the sub-unit will be one pattern (the vibration and sound of the Danger setting). 2. In-vehicle Patrol Light and Engine Stop * If a worker enters the Warning Distance, the patrol light will turn on and a buzzer will sound. * If a worker enters the Danger Distance, the engine of the heavy machinery will stop (the patrol light will also turn off and the sound will cease). 3. Up to 5 transmission units can be operated at the same site. 4. Operating Voltage: 24V 5. Waterproof equivalent to IPX5.

<Helmet-mounted receiver (subunit)> Main specifications 1. Detection distance (set in two stages: danger distance and warning distance) changes vibration and sound ● In the case of danger distance: Vibration continues, and the alarm sound also continues ● In the case of warning distance [when heavy machinery is approaching]: Vibration repeats at regular intervals of vibration ⇔ stop (approximately 1-second intervals), and the alarm sound also follows the same pattern, repeating sound ⇔ stop at regular intervals ● In the case of warning distance [when heavy machinery is far away or stopped]: Vibration repeats for about 0.5 seconds ⇔ stops for about 1.5 seconds, and the alarm sound also follows the same pattern, repeating sound ⇔ stop 2. LED lighting/blinking patterns ● When power is ON: Green light ● When power is OFF: Light off ● Battery level below 10% (in use): Red blinking ● During charging: Green blinking ● Charging complete: Light off ● At danger distance: Red light ● At warning distance: Orange light 3. Estimated usage time (battery capacity: 1000mAh) ● Approximately 30 hours (standby time) ● Approximately 3.5 hours (vibration and sound at danger distance) ● Approximately 5.5 hours (vibration and sound at warning distance) When the battery level falls below 10% during use, it will forcibly vibrate and continue to vibrate until the battery is depleted 4. Charged with a dedicated receiver charger (no USB terminal, using a conductive metal plate)
