also unipolar ionization chamber
Each FSP-951R-IV Series detector uses one of the panel’s addresses (total limit is panel dependent) on the NOTIFIER Signaling Line Circuit (SLC)
They are smart analog standard addressable devices available in plug-in versions (UIO) and also in 1-group mounting versions
The Simplex 2190-9155 provides an addressable interface between conventional zone devices and the host fire alarm control panel
this allows impedance changes in supervised loop to the monitored device detected
System Sensor 2251TB Intelligent Photoelectric smoke detector with thermal 2251 also unipolar ionization chamberThe System Sensor 2251TB is an Intelligent Addressable Photoelectric Smoke Sensor w Thermal (135F 57. 2C fixed) Sensor. The sensitivity of 200 Series detectors can be programmed using the control panel software to suit the environment. In addition, detector sensitivity is continually monitored and reported to the panel.
