The invention provides an alarm device suitable for wall mounting. The alarm device comprises a supporting board (21), at least three light emitting units (23) which are arranged on the supporting board (21) and are arranged at intervals along a roughly semicircular arc (C), and at least one reflection cup (25) which can be fixed on the supporting board (21), wherein each reflection cup is suitable for accommodating at least one light emitting unit (23), the reflection cups (25) roughly extend or are arranged into a semicircular ring structure, inner surfaces of the reflection cups are reflection surfaces and are constructed to reflect light emitted by the light emitting units (23) to one cuboid optical covering space (V), and the alarm device is arranged at the top-edge center position ofthe optical covering space (V). 本发明提出了种适于墙装的报警器，包括：个支撑板(21)；至少三个发光单元(23)，其设置在所述支撑板(21)上，且沿个大体上的半圆弧线(C)彼此间隔开地排列；至少个反光杯(25)，其能够固定在所述支撑板(21)上且每个反光杯适于容纳至少个所述发光单元(23)，所述反光杯(25)大体上延伸或排列成个半圆环形，所述反光杯的内表面为反射表面且构造成将所述发光单元(23)发出的光线朝向个立
