smoke detectors

FDL ( fix)

The FDL series fixed temperatune detectors use bi-metal snap discs as heat sensing elements, which close the alarm contacts when ambient temperature has reached a predeter-mined level of temperature. The detectors are automatically self-restoring after operation, when the ambient temperature falls below the operating temperature.

This series also includes water-proof types, which are suitable for use in highly humid environments such as a kitchen, a bathing room, a drying room.

The acid-proof tpye fixed temperature detector is durable for use in acid-rich environments such as a battery room, a plating plant, a sewage disposal plant and so on.

The anti-corrosive fixed temperrature detector has a heat sensor and a heat receiving plate coated with an anti-corrosive agent to be use in a space where the detector is subject to corrosive gases against copper or alminum. This type of fixed temperature detector is used, for instance, in a storehuose where filled with a fumigation gas as an insecticide for goods inside.
