Model PAD-5-MB also allows for expansion of notification appliances (NACs) <br /> that plug into each main board. Each PAD-5-MB main board connects via the P2 loop of a Siemens 'X'-series <br /> Device Loop Card (Model XDLC) connected to the Siemens Modular fire-alarm control panel (FACP). Up to 32 <br /> Siemens PAD-5 main boards or mixture expansion cards can connect to one (1) Model XDLC at a time. <br /> Additionally, Model PAD-5-MB has one(1)address,and is programmed with the Siemens Device Programmer <br /> 1 Test Unit, Model DPU. <br /> PAD-5-CLSA <br /> Used in conjunction with PAD-5 units, the 'Class AIB' Expansion Module (Model PAD-5-CLSA) provides <br /> additional connectivity of Siemens signaling appliances. In order for proper additional functionality, two (2) <br /> circuits, rated at 3A max., are wired as 'Class A', or four (4) circuits are wired as 'Class B'. Model PAD-5-CLSA <br /> uses one (1) address on the P2 loop. The address for Model PAD-5-CLSA must be the next sequential <br /> (numerical)address to that of the connected Model PAD-5-MB main board. E <br /> The Model DPU programmer 1 test unit is used to program the P2 address of each Model PAD-5-CLSA. <br /> There are LED indicators for each zone,as well as for the P2 interface and for the status of the card. <br /> Additionally, Model PAD-5-CLSA can be used in Sinorix®pre-action,deluge sprinkler,or for clean-agent <br /> control. There is an on-board releasing disconnect switch that can be used to disable power to both releasing <br /> circuits,thus preventing accidental discharge of clean agent during routine maintenance. <br /> Mounted to a <br /> PAD-5-MB Main <br /> Siemens _ <br /> Smart Infrastructure— Building Products —2 usa.siemens.comlfire <br />
