About This Product

PAD-3 - Power Supply with Black Enclosure. Designed for use with Siemens Building Technologies, Fire Safety Division fire alarm control panels, the PAD-3 is a Notification Appliance Circuit Expander with a built-in auxiliary power output. It is This power source is designed to provide the extra power required in buildings conforming to the Americans with Disabilities Act. The PAD-3 provides 6 amps of 24 VDC power for multiple uses. All 6 Amps can be directed to 4 Notification Appliance Circuits (NAC s). Each is rated at 3 A and is power limited. Either 1 or 2 inputs can control the four outputs. These outputs are compatible with all Fire Safety 24 VDC notification appliances. The PAD-3 can be configured so that the inputs can be programmed as steady outputs, ANSI temporal outputs, or synchronized strobe outputs. It can also be programmed so that one input will silence U-MHU Series horn/strobe horns while the strobes remain on using one set of wires. The PAD-3 also offers a 3 Amp auxiliary output for driving other portions of your fire alarm system such as door holders. This 24 VDC filtered output is power limited. When using this output, the total power available from the PAD-3 will not exceed 6 Amps. A trouble contact is provided for monitoring the PAD-3with a fire alarm panel through the input. It also has a Form C dry contact for trouble monitoring, allowing the user has the option of connecting it to a conventional fire alarm panel’s existing notification circuit, or controlling it with a TRI Series device on intelligent fire systems. The PAD-3 offers battery supervision and management as is required of fire alarm system components. Ground faults are transmitted as are any other trouble conditions. Trouble conditions not only change the state of the trouble contact in the unit, but they also break the notification circuit input to create a trouble signal in the fire alarm control unit. System 3 enclosures may also be used to house multiple PAD-3 modules in a single enclosure. Two modules are capable of sharing the same battery set when mounted in the same enclosure.
