2 System overview
These instructions cover installing the D298M (24 V), D298S (24 V), and D278S (12 V) Addressable Bases in an addressable system controlled by a G Series control panel (D9412G/ D7412G or later) 12 V Fire Alarm Control Panel (FACP) with a D8125 POPEX Module and 24 V auxiliary power1 provided by a UL 1481 regulated power limited power supply, or a D9124
24 V FACP.
The D298M base provides individual addresses on the FACP data expansion circuit and accepts:
–D263 and D263TH Photoelectric Smoke Detectors
–D287 and D288 Smoke Detector Bases, with the following detectors:
–D285 and D285TH Photoelectric Smoke Detectors
–D286 Ionization Smoke Detector
–D603, D604, and D605 Heat Detectors
When used with the D285 Series Detectors, the D298M base indicates chamber check trouble to the control panel through the POPIT bus. The chamber check trouble indication appears on the control stations as a fire trouble.
The D298M base also provides connection points for supervised circuits with up to 19 twowire conventional detectors reporting to the D298M’s address. When the D298M base is combined with a PAM 4 Relay Module, one Form “C” output (normally open [NO]/common [C]/ normally closed [NC]) provides auxiliary functions such as recalling an elevator or closing fire doors.
The D298S and D278S bases have a built in POPIT to provide individual addresses on the FACP data expansion circuit. These bases accept:
–D285 and D285TH Photoelectric Smoke Detectors
–D286 Ionization Smoke Detector
–D603, D604, and D605 Heat Detectors
1 Depending on the current requirements of the application for the D278S base, power can be provided by the FACP or by a UL 1481 regulated power limited auxiliary power supply
