Notifier SFP-5UD Conventional Fire Alarm Control Panel
The Notifier SFP-5UD is a UL Listed 5-zone conventional fire alarm control panel designed for small to medium-sized fire signaling applications. It includes a built-in DACT (Digital Alarm Communicator Transmitter) and supports remote upload/download for faster service and configuration.
What does the SFP-5UD fire alarm control panel do?
The SFP-5UD supervises initiating devices (smoke/heat detectors, manual pull stations, waterflow and tamper switches) and activates notification appliances (horns, strobes, bells) when an alarm condition is detected. It also supervises key system conditions including wiring integrity, AC power, and battery status.
- Five Class B IDCs (Class A option via N-CAC-5X module)
- Four Class B NACs rated up to 2.5A per NAC (Class A option via N-CAC-5X)
- 3.0A total system signaling power
- Built-in DACT with remote upload/download support
- 80-character LCD with backlighting and keypad
- Up to 8 ANN-BUS devices (LCD annunciators, LED modules, printer gateway, etc.)
- Programmable NAC patterns (silence inhibit, autosilence, temporal/steady, strobe sync)
- 3 Form-C relays (factory defaults: Alarm, Trouble, Supervisory)
- Optional IP communicator for internet monitoring modules
Why choose a 5-zone conventional panel like SFP-5UD?
If your building layout is straightforward, conventional zoning can deliver strong performance with simpler configuration. The SFP-5UD adds modern usability (LCD, walk test support, remote programming) while keeping conventional zone architecture.
- Clear zone-based indication for faster response to the affected area
- Flexible NAC programming for different evacuation signaling strategies
- Remote upload/download reduces site visits for certain service tasks
- ANN-BUS expandability for remote annunciation and reporting
- Small commercial buildings with multiple areas (zones)
- Schools and institutional blocks
- Warehouses with distinct compartments
- Small-to-mid industrial facilities
What are the key technical specifications of the SFP-5UD?
Use these specifications to confirm circuit capacity, NAC loading, and auxiliary power requirements during design and commissioning.
| Category | Specification |
|---|---|
| Zones / IDCs | 5 × Style B (Class B) initiating device circuits (Class A optional via N-CAC-5X) |
| NACs | 4 × Style Y (Class B) NACs (Class A optional via N-CAC-5X) |
| NAC current capacity | Up to 2.5A maximum per NAC; 3.0A total system power (SFP-5UD) |
| Relays | 3 × Form-C relays (factory defaults: Alarm, Trouble, Supervisory) |
| Special application resettable power | 24VDC nominal; up to 500mA (jumper selectable resettable/nonresettable) |
| User interface | 80-character backlit LCD + keypad; piezo sounder; walk test support |
| Communications | Built-in DACT; optional IP monitoring modules (internet monitoring) |
| Annunciators | Up to 8 ANN-BUS devices (LCD/LED annunciators, printer gateway, etc.) |
| Listings | UL Listed (File S635); other listings may apply by configuration/region |
How do I specify the SFP-5UD correctly for a project?
Start with zoning and notification requirements, then confirm power and reporting needs. This helps avoid under-sizing NAC capacity and ensures the right signaling strategy for the building.
- Zones: confirm you need up to 5 Class B zones (or plan Class A with N-CAC-5X).
- NAC load: total current per NAC (≤ 2.5A) and total panel power (3.0A).
- Monitoring: phone line DACT vs. optional IP monitoring requirement.
- Remote annunciation: determine how many ANN-BUS devices you need (up to 8).
- Aux power: confirm 24V resettable power needs for 4-wire detectors (up to 500mA).
- N-CAC-5X: Class A converter option for NACs and IDCs
- ANN-BUS devices: N-ANN-80 (LCD), N-ANN-LED, N-ANN-RLY, N-ANN-S/PG, etc.
- Printer interface: serial/parallel printer reporting support
- IP monitoring modules: for internet monitoring where applicable
