Title:
Optical alarm equipment and an optical alarm system
Document Type and Number:
Japanese Patent JP5943420
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To synchronize deviation of light emission control with light emission control of another optical alarm apparatus with simple configurations.SOLUTION: An optical alarm apparatus constituted so as to be connectable in parallel with an optical alarm line includes: a light emission part subjected to light emission control on the basis of a light emission pattern; a setting part for setting the optical alarm apparatus to a first state (master); and a control part for, when the optical alarm apparatus is set to the first state (master) by the setting part, performing the light emission control of the light emission part on the basis of a first light emission pattern, and for performing output based on a second light emission pattern to be used for the light emission control of another optical alarm apparatus, and in which a deviation between light emission timings to be specified by the first light emission pattern is within a predetermined time.
