Addressable Single Input Monitor Module That Monitors One Class B Circuit on a Single SLC Loop Address with PAD Protocol Communication
The Potter PAD100-SIM is an addressable single input fire alarm monitor module that monitors one Class B initiating device circuit while consuming only a single SLC loop address. This makes it the right choice for locations where a single contact-type device such as a waterflow switch, tamper switch, or pull station needs to be brought onto the addressable loop without wasting a dual-input module on a single point. The PAD100-SIM uses the PAD protocol for addressable communication on the SLC loop, with a standby current of just 240 microamps to keep total loop power draw low across large systems.
The PAD100-SIM is part of the Potter PAD Series and shares the same compact 4.17 x 4.17 x 1.14-inch housing as the dual-input PAD100-DIM, mounting directly to a standard 4-inch square or double gang electrical box. A red LED flashes during normal panel polling and blinks rapidly when the 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, with a 5.1K ohm end-of-line resistor supervising the circuit. Up to 127 PAD100-SIM modules can be installed on a single SLC loop.
Where the PAD100-SIM Fits
- Standalone waterflow or tamper switch monitoring points where only one initiating device needs to connect to the addressable loop at a given location, the single-input design conserves SLC addresses compared to using a dual-input module for a single device, and the 240 microamp standby current minimizes loop power consumption across systems with hundreds of addressable devices
- Pull station connections and door holder relay monitoring where a single Class B circuit ties one contact-type device into the Potter IPA Series panel, the compact housing fits inside existing electrical boxes without adding junction boxes, and the red LED provides instant visual confirmation during walk testing and alarm events
- Warehouse and industrial sprinkler zones with single-device risers where each riser has only a waterflow switch without a paired tamper, the PAD protocol communication maintains reliable polling across long wire runs, and the 32 to 120 degree Fahrenheit operating range handles mechanical room and riser closet environments
What the PAD100-SIM Delivers
- Single Input on a Single Address: Monitors one Class B initiating device circuit while using only one SLC loop address. Connects waterflow switches, tamper switches, pull stations, and other contact-type devices to the addressable loop without consuming a dual-input module.
- 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 Circuit: The 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.
What Does a Fire Alarm Monitor Module Do
A fire alarm monitor module connects a conventional contact-type device to an addressable fire alarm panel by monitoring the state of an initiating device circuit and reporting changes back to the panel over the SLC loop. When a connected device such as a waterflow switch, tamper switch, or pull station activates, the monitor module detects the change in circuit state and transmits its unique address to the panel, which identifies the exact device location and initiates the programmed response. The PAD100-SIM handles this for a single Class B circuit on one SLC address, making it the efficient choice when only one device needs monitoring at a given location.
