Technical Specifications:

Input Voltage: AC 220V

DC Current: ≤10 mA

Dynamic Current: ≤500 mA

Operating Voltage: DC 5V, DC 12V

Feature:

1. Automatic alarm system for real-time monitoring and alerting of grounding system conditions.

2. Set the ground monitoring resistance value according to the requirement of working ground resistance, and trigger an audible and visual alarm when the resistance exceeds the set value.

3. An audible and visual alarm is triggered when the grounding system is disconnected, effectively enhancing the reliability of the grounding system. The LCD display features a lockable configurator. (As shown in Figures 3 and 4) Suitable for work environments with high requirements for grounding resistance values.

4. Grounding system resistance monitoring is adjustable (0-500Ω), and an immediate audible and visual alarm is triggered when the loop resistance of the ground wire exceeds the set value.

5. Can also be used for factory and garage security systems. (As shown in Figure 2)

Operation:

Connect the police light wire to the alarm output connector on the back of the cabinet, following the positive and negative poles (red wire for positive; black wire for negative).

2. Connect the two grounding pins at the back of the cabinet to the workbench surface and the earth ground wire, respectively. (As shown in Figure 1)
