Fire, the fire process is generally accompanied by smoke, heat, light, three kinds of combustion products. Early in the fire, because the lower temperature, more material in the smoldering stage, produce a lot of smoke. Smoke is an important feature of early fire, smoke fire detector is able to visible or invisible smoke particles in response to the fire detectors. It is part of the smoke detection is converted to electrical signal changes in the concentration of purpose to achieve a kind of alarm device.
Smoke fire detector with ionization smoke type, photoelectric type smoke, laser type, and so are several types of smoke. Suitable for smoke fire detector installed in the event of fire or smoke more prone to smoldering place; it should not installed in the usual smoke ventilation speed greater or place. Today we recommend you several smoke detectors, high to low prices for different building, for when you choose as a reference.
I. XP95 addressable analog ionization smoke detector 55000-520PRCAPOLLO Apollo
XP95 addressable analog ionization smoke detector
Price : 538 yuan Supply Enterprise: Shanghai River Sea Trading Co., Ltd.
Supply quantity: Open Details Detector with a white poly resin plastic shell of carbon acids, top of the smoke into a wind of mouth, the back of the sliding contact with stainless steel sheets, used in connection with the detector base.
Detector inside a printed circuit board, circuit board side of the installation of an ion chamber, which Am241 source of radiation, the other side of the circuit board installed address intercepted, signal processing and system communication circuit .
When the detector installed in the detector base, by a system alarm control panel to provide voltage and current to the detector, the detector is in standby working condition. At this point the internal sources of radiation detector internally generated ionization in the ionization chamber, automatic formation of positive and negative ions, and produce a small current and voltage. Case of fire, smoke particle detector into the smoke through mouth into the ion chamber, one of the positive and negative ions are adsorbed on the smoke particles, causing the normal current and voltage changes. Alarm system control panel inside the detector that small changes in voltage and current monitoring process, until it reaches a certain level will send alarm signal.
