Fire detection apparatus
A fire detection apparatus 1 A includes a heat detection unit 110 A provided such that a part of the heat detection unit 110 A is accommodated in an outer cover 20 A and another part of the heat detection unit 110 A is exposed to an outside of the fire detection apparatus 1 A through an insertion hole 120 A formed in a top surface portion 22 A, and a guard portion 130 A which is provided to cover a periphery of the insertion hole 120 A and another part of the heat detection unit 110 A in the top surface portion 22 A and has a plurality of ribs, in which a material of a rib corresponding to a first guard side rib 131 A among the plurality of ribs is made different from a material of some other ribs, or a shape of the first guard side rib 131 A among the plurality of ribs is made different from a shape of some other ribs.
1. A fire detection apparatus for detecting a fire in a monitored area, the fire detection apparatus comprising:
a housing;
a first detection space for performing detection of a first detection target contained in a gas flowing in from an outside of the housing on the inside of the housing;
a second detection space located on the inside or the outside of the housing, the second detection space being provided to perform detection of a second detection target; and
a partition wall provided in the housing, the partition wall being provided to partition the first detection space or the second detection space so that inhibiting the gas flowing into the first detection space from flowing out to the second detection space is allowed,
wherein the first detection space includes,
a first detection space body in which detection of the first detection target is performed, and
an inflow space for allowing the gas containing the first detection target to flow into the first detection space body,
the fire detection apparatus further comprises an insertion hole provided in a portion facing the inflow space in a portion of the housing to insert a part of a second detection target detecting unit that detects the second detection target accommodated in the housing, into the second detection space, and
the partition wall is configured to surround at least a part of a periphery of the second detection target detecting unit and the insert hole in the inflow space.
