How to wire the alarm switch
The alarm switch is an important part of the security system, and correct wiring can ensure its normal operation. This article will introduce the wiring method of the alarm switch in detail, and provide hot topics and hot content in the past 10 days to help readers better understand related technologies.
1. Basic wiring method of alarm switch
The wiring methods of alarm switches are mainly divided into two types: normally open (NO) and normally closed (NC). The following are common wiring steps:
| Wiring type | Wiring method | Applicable scenarios |
|---|---|---|
| Normally open (NO) | The circuit is open when the alarm switch is not triggered and closed when it is triggered. | Door and window alarm, intrusion detection |
| Normally closed (NC) | The circuit is closed when the alarm switch is not triggered and disconnected when it is triggered. | Fire alarm, emergency button |
2. Precautions for wiring
1.Power matching: Make sure the voltage and current of the alarm switch match the system to avoid damaging the equipment.
2.line protection: Use appropriate cables and install fuses or circuit breakers to prevent short circuits.
3.Grounding treatment: Make sure the equipment is well grounded to avoid electromagnetic interference or leakage risk.
