Intelligent System Smoke Detectors - ANSWER-Send information about smoke conditions to the control unit. The detector indicates the location of the alarm and provides environmental change information to the panel. Smoke Detectors with Control Output Functions - ANSWER-When smoke detectors are installed on an initiating device circuit an are used for controlling operation (fan shutdown or elevator recall) with other devices installed on the same circuit, the control function must perform correctly, even with all other devices on the circuit in an alarm condition. Smoke Dampers - ANSWER-Open and close when required to provide fresh air or to stop smoke passage. Fire Dampers - ANSWER-Close when a rise in temperature occurs and stay shut to stop fire from passing through a barrier. Rate-of-Rise Heat Detectors - ANSWER-Activate the alarm when the room temperature increases at a rapid rate. This type of detector is more sensitive and does not have to be replaced after it has activated the fire alarm. Fixed-Temperature Heat Detectors - ANSWER-Activate the alarm when the detector components melt at a preset temperature level. Normally require replacement after they have sounded an alarm.
