The multisensor construction is similar to that of the optical detector but uses a different
\nlid and optical mouldings to accommodate the thermistor temperature sensor. The
\nsectional view (below) shows the arrangement of the optical chamber and thermistor.
\nThe signals from the optical smoke sensing element and the temperature sensor
\nare independent, and represent the smoke level and the air temperature
\nrespectively in the vicinity of the detector. The detector\u2019s microcontroller processes
\nthe two signals. The temperature signal processing extracts only rate of rise
\ninformation for combination with the optical signal. The detector will not
\nrespond to a slow temperature increase – even if the temperature reaches a high
\nlevel. A large sudden change in temperature can, however, cause an alarm without
\nthe presence of smoke, if sustained for 20 seconds.
\nThe processing algorithms in the multisensor incorporate drift compensation. The
\ncontrol panel must not have a drift compensation algorithm enabled.
\nThe sensitivity of the detector is considered the optimum for most general
\napplications since it offers good response to both smouldering and flaming fires.<\/p>\n","protected":false},"excerpt":{"rendered":"
