System Sensor 2251TB Intelligent Photoelectric smoke detector with thermal 2251 compatible for use with ONYX®

compatible for use with ONYX® Series nodes such as the NFS2- 3030

The Simplex 2190-9155 provides an addressable interface between conventional zone devices and the host fire alarm control panel

Communication takes place over the power (+ and –) lines

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)

Activate on-board end-of-line resistors by setting “ON” switch SW100 (Channel A)
