P/S NAC EXT 6 AMPS

PAD-3 Siemens Power Expander
The Model PAD-3 Siemens from Siemens Building Technologies, Inc. is a notification and auxiliary power expander that provides up to 6 amps of 24 volt DC for powering notification appliances and auxiliary devices. The PAD-3 provides its own AC power connection, battery charging circuit, and battery connections. Used with a fire alarm control unit, this enables you to connect and distribute power to many more devices than your control unit may normally allow.

The PAD-3 Siemens has two optically isolated inputs that provide the connection from the fire alarm control unit notification appliance circuit to the PAD-3. The inputs also provide a connection for returning a trouble condition to the control unit notification appliance circuit.

Used with Siemens Fire Safety fire alarm control panels (FACPs), the Distributed Power Supply Unit (Model PAD-3 series) is a NAC expander with a built-in, auxiliary-power output. Each unit is designed to provide additional power for visual indicators in buildings that conform to the Americans with Disabilities Act (ADA).

The fire alarm control unit supervises its notification appliance circuit used for communicating with the PAD-3 the same way it supervises ordinary NACs. The inputs on the PAD-3 monitor the polarity of the voltage coming from the fire alarm control unit's NACs to determine when to operate the notification appliance circuit outputs. The PAD-3 emulates the trouble behavior of a NAC by opening the EOL supervision current for trouble conditions.
