Pre alarm function: | When the rescuer is in the automatic working state, it has the pre alarm function. When the static time exceeds the allowable static time, it shall send out a fast intermittent pre alarm sound signal. During the prediction tube, when the working orientation of the rescuer changes or the plane uniform motion with the working speed rate of the rescuer not less than 5m / s, the pre alarm sound signal shall be released immediately. |
Automatic alarm function: | When the rescuer is in the automatic working state, when the static time exceeds the sum of the allowable static time and the predicted alarm time, it shall send out continuous alarm sound signal and azimuth indication frequency flash signal. During the alarm period, the alarm sound signal azimuth indication frequency light signal is not affected by the change of the working azimuth or movement rate of the rescuer, and can only be eliminated manually. |
Manual alarm function: | When the pager is in manual working state, it shall send out the same alarm sound signal and azimuth indication frequency flash signal as the automatic alarm function. During manual alarm, the alarm sound signal and azimuth indication frequency flash signal shall not be affected by the change of working azimuth or movement rate of the pager. |
Low voltage alarm function: | When the voltage of the power supply battery of the pager is lower than 80% of the rated voltage, a slow intermittent alarm sound signal or optical signal different from the alarm sound signal shall be sent |
Communication function: | when the communication type pager is in the alarm state, it will send out alarm sound signal and azimuth indication frequency flash signal. At the same time, the pager shall be able to transmit signals to the receiving terminal for identification, and receive and identify the signals transmitted from the receiving terminal. |
TChange over switch: | The "off manual and automatic" change-over switch shall be set for the pager. The change-over switch shall be flexible, reliable, durable and equipped with anti misoperation structure. |
Allowable rest time (s) | 30.09 |
Pre alarm time (s): | 15.18 |
Pre alarm sound level loudness (dB): | 101.7 |
Alarm sound level loudness (dB): | 101.0 |
Low voltage alarm sound level loudness(dB): | 100.1 |
Continuous alarm time: | 600min |
continuous startup time: | 60H |
weight: | 163.8g |
Waterproof performance: | The rescuer is placed in a container with a water depth of 1.5m for 2h, no water penetrates into the rescuer, and the rescuer can work normally. |
