Test or certification item 测试名称：EN 54-12 (Linear/optical beam smoke detectors) 火灾探测和报警系统—第12部分：感烟探测器—光束线型探测器
Test or certification info 测试和认证相关内容:
EN 54-12测试项目：
1. 标准火试验 Standard Fire Tests（核心）
多组标准烟雾火情，验证不同减光阈值下的报警响应；检验光束衰减触发报警逻辑。
2. 光束对准与偏移测试 Alignment & Beam Drift
发射器/接收器安装偏移、微小位移，验证探测器是否正常工作、故障告警。
3. 灵敏度与减光等级 Sensitivity & Obscuration Levels
检验报警阈值、阈值重复性，区分火警与故障（脏污漂移补偿）。
4. 环境耐久测试 Environmental Endurance
高低温、湿热、振动、冲击、二氧化硫腐蚀、防尘防水。
5. 供电适应性 Supply Variation
电压上下波动，考察灵敏度、故障监控稳定性。
6. 电磁兼容 EMC Immunity 射频、电快速脉冲等干扰，防止误报。
7. 杂散光抗扰测试 Stray Light Immunity 外部强光干扰，避免误触发。
8. 机械与可靠性 Mechanical & Fault Monitoring 外壳强度、光路遮挡故障报警、脏污监测功能。
