Model OH121 from Siemens Industry ??? Fire Safety is a photo / thermal smoke detector that contains a thermal sensor. When the sensor is utilized, an Alarm condition will trigger when the temperature reaches 135°F ??? at this point, the detector will also lock into Alarm condition.
The magnet-test feature allows for Model OH121 to be tested without the use of a heat gun, providing quick testing for installers and test personnel to prove the integrity of the wiring and proper connection to the fire alarm control panel (FACP).
The auto-sensitivity feature for Model OH121 stems from the internal, self-monitoring circuitry, and provides dynamic verification of sensitivity and / or required maintenance. The auto- sensitivity feature is displayed by Siemens unique (3) three-color LED provided locally on the detector ??? and optionally with the various remote LED indicators.
