| Abstract: | Analyses the signal interferences which come from the inside and outside of automatic fire alarm systems. Some measures to enhance the reliability of the fire alarm systems such as taking power line filter, interference controller, soft magnetism and insolated transformer are brought forward to prevent inner signal interferences and other measures such as shielding, grounding, taking twisted-pair connection and magnetism line filter can be used to control outer signal interferences. |
| Keywords: | automatic fire alarm system signal interference control measures |
