Prerequisites

Step by Step Instructions

1. Here is your Electronic Buzzer, please read the product guide for this sensor to determine which lead is the power positive (ALARM OUT C1) and which lead is the Negative/Ground ⏚ in the event that the alarm is unidirectional and not bidirectional.

2. Also refer to the power requirements and specifications in order to make sure you are using the proper power supply unit for this device. Also Identify your power supply leads PSU+ and PSU- or Negative/Ground ⏚. PSU+ will go to ALARM OUT NO1.

3. Take the Electronic Buzzer and seat the positive lead it into the power block corresponding to ALARM OUT C1

4. Take the PSU and seat the positive lead it into the power block corresponding to ALARM OUT NO1

5. Now seat both the PSU and Electronic Buzzer's Negative/Ground ⏚ leads into any of the corresponding alarm out Negative/Ground ⏚ terminals on the NVR/HCVR/DVR

6. Now double check and make sure you have everything setup according to all of your device's (NVR/HCVR/DVR PSU and Electronic Buzzer) specifications. Also check that the leads are seated properly in the power block and are making full metal to metal contact with the power block.

7. Now Connect the power block to the corresponding ALARM OUT area, and plug in your power supply.

8. For testing purposes use this setup on your NVR/HCVR/DVR to make sure your setup works. Main Menu > Event (under settings) > click on Alarm tab > Enable Alarm > Select Alarm Out 1 > Enable Buzzer > click Apply.

9. Now trigger you magnetic sensor and you should hear the NVR/HCVR/DVR's Buzzer, and also now your Electronic Buzzer should be alarming out.

Now you know how to setup both alarm inputs (magnetic sensor) and powered alarm outputs (Electronic Buzzer)!

Please check all of your systems (NVR/HCVR/DVR PSU and Electronic Buzzer) power requirements and specifications before plugging things in without any understanding of how it works, as this can result in possible electrical fires or even the death of your systems (NVR/HCVR/DVR PSU and Electronic Buzzer).
