Sargent 1256NB-8710G 84" Fire Rated Surface Mount Vertical Rod Exit Device with Electric Latch Retraction
The Sargent 1256NB-8710G is a UL listed, fire rated surface mount vertical rod exit device built for 48" × 84" narrow stile doors. The 8710G electric latch retraction function integrates directly with access control systems — 24VDC operation, 600mA draw during retraction, 250mA maintained in the dogged position — enabling remote dogging and free-egress scheduling without mechanical dogging at the device. Finished in 32D satin stainless steel. Right Hand Reverse (RHR) handing.
Key Features
- Electric Latch Retraction (ELR): 24VDC, 600mA retraction / 250mA maintained — integrates with access control panels, time-clock schedulers, and fire alarm systems.
- Remote Dogging: Electrically holds the latch retracted; eliminates the need to manually dog the device at the door.
- Fire Rated Construction: UL listed for fire-rated door assemblies; meets NFPA 80 and IBC egress requirements for exit device applications.
- UL Class II Circuitry: Low-voltage wiring compliant with NEC Class II requirements — no conduit required in most jurisdictions.
- Surface Mount Vertical Rod: Top and bottom rods engage the door frame at head and threshold; no mortise prep required in the door.
- Narrow Stile Door Compatibility: Designed for 48" wide × 84" tall narrow stile aluminum or hollow metal doors.
- Exit-Only / No Bottom Rod Option: No trim, exit-only configuration; no bottom rod simplifies installation on doors with threshold constraints.
- 32D Satin Stainless Steel Finish: Corrosion-resistant finish suited for high-traffic and exterior vestibule applications.
- Grade 1 Commercial Duty: Meets ANSI/BHMA A156.3 Grade 1 cycle and force requirements.
