Addressable Dual Input Module That Monitors Two Class B or One Class A Circuit on a Single SLC Loop Address The Potter PAD100-DIM is an addressable dual input fire alarm module that monitors either two Class B initiating device circuits or one Class A circuit while consuming only a single SLC loop address. This allows installers to monitor a paired waterflow switch and valve tamper switch at the same riser location without using two separate addresses on the loop, cutting module counts and simplifying system programming on Potter IPA Series panels. The compact 4.17 x 4.17 x 1.14-inch housing mounts directly to a standard 4-inch square or double gang electrical box. The PAD100-DIM uses the PAD protocol for addressable communication on the SLC loop, with a standby current of just 240 microamps to minimize loop power consumption across large systems. A red LED flashes during normal panel polling and blinks rapidly when either input activates, providing instant visual identification during walk testing and alarm events. Each IDC supports up to 100 ohms of wiring resistance and 1 microfarad of capacitance, and a 5.1K ohm end-of-line resistor supervises each circuit. Up to 127 PAD100-DIM modules can be installed on a single SLC loop. Where the PAD100-DIM Fits Sprinkler riser rooms and valve monitoring stations where a waterflow switch and tamper switch sit within feet of each other at the same riser, the dual input design eliminates the need for two separate monitor modules, and the single SLC address conserves loop capacity for larger systems with hundreds of addressable devices Commercial buildings and high-rise towers where multiple floors each require paired waterflow and tamper monitoring, the compact housing fits inside existing electrical boxes without adding junction boxes, and the 240 microamp standby current keeps total SLC loop current draw manageable across large device counts Warehouse and industrial facilities where sprinkler zones cover large areas and each zone needs both flow and valve supervision, the Class A and Class B wiring flexibility accommodates the facility wiring topology, and the 32 to 120 degree Fahrenheit operating range handles mechanical room environments What the PAD100-DIM Delivers Dual Input on a Single Address: Monitors two Class B initiating device circuits or one Class A circuit while using only one SLC loop address. Pairs waterflow and valve tamper switches at a single monitoring point without doubling the module count or consuming additional loop capacity. Low-Current Addressable Communication: 240 microamp standby and alarm current on the SLC loop minimizes power draw across large systems. PAD protocol communication with red LED status indicator that flashes during polling and blinks rapidly on input activation. Up to 127 modules per SLC loop. Supervised IDC Circuits: Each initiating device circuit supports up to 100 ohms of wiring resistance and 1 microfarad of capacitance. 5.1K ohm end-of-line resistor provides continuous circuit supervision. Operating temperature range of 32 to 120 degrees Fahrenheit with humidity tolerance to 93% non-condensing. Compact Mounting: 4.17 x 4.17 x 1.14-inch housing mounts to a standard 4-inch square or double gang electrical box. 24V DC operating voltage from the SLC loop. Compatible with Potter IPA Series fire alarm panels.
