Fixed temperature heat detectors will sound the alarm when the temperature at the detector reaches a pre-set limit, typically 135 or 200 degrees. These devices are generally used in attics, boiler rooms, or garages. Rate of rise heat detectors will sound the alarm if the temperature at the detector increases at a very rapid rate, typically 15 degrees per minute. These units also have a fixed temperature detector included. They can be used in areas where smoke detectors are not suitable such as kitchens, or work shops.
Pull stations are devices that can be manually activated to signal a fire.
If used, they should be mounted by the exits of the house so that they can be triggered as you leave your house during a fire. These units can either be silent or activate your sounders. If you desire the silent version than you must have your system monitored. You should bear in mind that activating these units may alert the intruder to your actions, so care must be exercised in their use. Panic devices can be fixed buttons, portable wireless buttons, or a special combination at the keypad.
