提供CTI-TC105感温火灾探测电缆105批发价格_矿用电缆相关-上海道夫自动化仪表工程有限公司
Electrical protective signaling systems are configurations of components used to produce alarm signals indicative of fire, smoke,
sprinkler waterflow or other emergency and to produce supervisory signals indicative of conditions needing attention with respect to
protection equipment or watch service. System configurations are classified according to where and how the signals are received.
The categories are commonly designated as local, municipal, remote station, proprietary, emergency voice/alarm communication,
emergency communication, and central station. Auxiliary systems are either local or proprietary systems interconnected with a
municipal system.
This category presents the major system component categories and the integrated system configurations. The selection of
components to form a hybrid system should be made only by those skilled in system design. Also, the suitability of any system
application should be judged on the basis of the hazard(s) being protected.
Alarm Signal Initiating Devices
Alarm signals are initiated either automatically or manually. Automatic detectors respond to changes in characteristic phenomena
associated with fire or other emergency conditions.
