Wholesale PricingThe Potter PAD-100OROI (P/N 3992702) is an addressable one relay, one input module for Potter fire alarm systems. It provides one programmable Form-C relay output and one supervised input circuit on a single SLC address. The input can monitor a contact-type initiating device such as a waterflow switch, tamper switch, or fire suppression pull station, while the relay can be configured for building system control functions like door holder release, elevator recall, or fan shutdown. The compact design mounts easily inside or adjacent to the field device enclosure.
The addressable fire alarm slc architecture means each PAD-100OROI reports its status individually to the fire alarm control panel — giving technicians precise location data for any alarm or fault condition. For fire alarm parts suppliers and contractors managing commercial fire alarm equipment supplies, the PAD-100OROI is the most commonly specified single-function interface module in the Potter PAD series, ideal for locations that need one monitoring input paired with one control output without the additional capacity of the two-relay TRTI model.
This module is used throughout commercial fire alarm system installations wherever a single monitored device needs to trigger a single building system response — for example, a sprinkler waterflow switch triggering an HVAC damper, or a fire damper fusible link position switch reporting to the fire alarm control panel. It is a foundational building block of any integrated Potter addressable system and a standard stock item for any fire alarm supply store serving commercial contractors.

Assign a unique address on the fire alarm SLC loop before installation. Wire the supervised input to the monitored device using Class B wiring with an end-of-line resistor sized to the panel specification. Connect the relay output to the controlled building system per the system design drawings. Verify all functions during commissioning — activate the input device and confirm the relay operates correctly and the fire alarm control panel logs the correct event. Document all zone assignments and test results in the fire alarm inspection and test records. Annual testing of both the input and relay functions is required per NFPA 72. Update fire alarm inspection stickers after each test cycle.
What is the difference between the PAD-100OROI and PAD 100-TRTI?
The PAD-100OROI (3992702) provides one relay and one input. The PAD 100-TRTI (3992701) provides two relays and two inputs. Choose the OROI for single-device monitoring and single-output control. Choose the TRTI when two separate devices need to be monitored and two separate building systems need to be controlled from one SLC address.
Can this module monitor a manual pull station for a fire suppression system?
Yes. The supervised input is compatible with normally-open contact devices including fire suppression system pull stations and fire suppression pull station accessories. This allows manual pull station activations to be monitored and logged on the addressable fire alarm slc loop with precise location identification.
