Wholesale PricingThe Potter PAD 100-DIM (P/N 3992703) is an addressable dual input module for Potter fire alarm systems. It provides two independent supervised input circuits on a single SLC address, allowing two separate contact-type initiating devices to be monitored and individually reported to the fire alarm control panel. Compatible devices include waterflow switches, tamper switches, manual pull stations, and any other normally-open contact initiating devices used in commercial fire alarm systems.
The dual input design makes the PAD 100-DIM an efficient choice for locations where two nearby devices need to be brought onto the fire alarm slc loop without consuming two separate SLC addresses. This is particularly valuable in large addressable fire alarm systems where SLC address capacity is a design constraint. By consolidating two supervised inputs onto one addressable module, system designers can maximize the number of monitored points within the panel's address limit.
For fire alarm parts suppliers and fire alarm equipment supplies contractors, the PAD 100-DIM is a cost-effective monitoring-only module for locations that need two device inputs but no relay output. It complements the PAD-100OROI (one relay, one input) and PAD 100-TRTI (two relays, two inputs) in the Potter PAD interface module family — together covering the full range of input and output combinations needed for commercial fire alarm signalling system integrations.

Assign a unique address on the fire alarm SLC loop before installation. Each of the two input circuits requires separate end-of-line resistors and can be assigned to different alarm or supervisory zones at the fire alarm control panel. Wire each input to its respective device using Class B wiring per the Potter wiring diagram. During commissioning, activate each input device independently and verify the correct zone response at the panel. Document address assignments and test results in the fire alarm inspection and test records. Annual testing of both input circuits is required per NFPA 72 — verify each input generates the correct signal independently and update fire alarm inspection stickers after each test cycle.
Can both inputs on the PAD 100-DIM be assigned to different alarm zones?
Yes. Each of the two supervised inputs can be independently assigned to different alarm zones, supervisory zones, or trouble zones at the fire alarm control panel. This allows the PAD 100-DIM to monitor two completely different systems — for example, a waterflow switch on one input and a fire suppression pull station guard circuit on the other — from a single SLC address with independent reporting.
Does the PAD 100-DIM have any relay output capability?
No. The PAD 100-DIM is a monitoring-only module with no relay outputs. If control output capability is also needed at the same location, use the PAD-100OROI (one relay, one input) or PAD 100-TRTI (two relays, two inputs) instead.
