The Potter Electric Signal PAD200-DUCTR is an analog addressable duct smoke detector with an integrated Form C relay. First, it ships complete with housing and PAD200-DD head. Then, the on-board relay drives HVAC fan shutdown or damper control. As a result, integrators get duct detection plus a local control output in a single device.
Potter Electric Signal PAD200-DUCTR relay
The PAD200-DUCTR adds one Form C relay rated for fan shutdown and damper control. Specifically, the contacts handle 8 A at 30 VDC, 10 A at 120 VAC, or 10 A at 250 VAC. In addition, the relay drives building automation interfaces and HVAC controls directly. Therefore, the detector typically replaces an external relay accessory.
The PAD200-DUCTR also supports the PAD100-DRTS remote test switch. Furthermore, it works with MS-RA, MS-KA/R, and MS-KA/P/R remote annunciators. As a result, building staff can test and indicate the detector from a remote location.

Remote test and annunciator ordering
Order remote accessories based on staff workflow. Specifically, PAD100-DRTS (stock 3992711) provides supervised remote test. In addition, MS-RA (1000256) is a remote annunciator. Also, MS-KA/R (1000254) adds a test/reset switch. Finally, MS-KA/P/R (1000253) adds a test switch with pilot. Therefore, four remote-accessory options cover most install scenarios.
