Remote Capable Emergency Lights – Spec Guide
- Remote capacity (watts): Confirm total remote-head wattage the unit supports and verify 90-minute runtime with on-board heads plus remotes attached.
- Remote circuit voltage: Match remote heads to the output voltage (e.g., 3.6 V / 6 V / 12 V) and observe polarity/terminal conventions.
- Wiring & voltage drop: Size conductors and limit run lengths so heads receive required voltage at load; follow manufacturer voltage-drop tables for each circuit voltage and wattage mix.
- Circuit count/zoning: Use separate remote circuits by corridor/area to simplify testing, isolation, and future maintenance; label junctions and terminations clearly for inspections.
- Head compatibility: Align remote head wattage, lumen output, beam, and environment rating (damp/wet, vandal-resistant) with spacing and site conditions.
- Egress photometrics: Lay out for ≈ ≥1 fc average and ≥0.1 fc minimum along the path at 90 minutes; adjust aiming/beam options accordingly.
- Batteries: Maintenance-free Ni-Cd or lithium; check capacity (Ah), recharge time, ambient range, and expected service life for maintenance planning.
- Electronics: Universal 120/277 VAC input, brownout protection, low-voltage disconnect, status LED, and accessible test switch (local or remote as required).
- Self-testing diagnostics: Prefer units that automate monthly/annual tests and indicate distinct faults for on-board heads vs remote circuits if available.
- Environment & rating: Specify damp/wet-location housings, corrosion-resistant hardware, and heater options for cold storage or exterior vestibules.
- Mounting & service: Provide clear access to battery/charger; include junction boxes for remote taps and strain relief/conduit support along runs.
- Documentation: Maintain a one-line showing remote loads, run lengths, conductor sizes, and measured test results for AHJ review.
FAQs About Remote Capable Emergency Lights
What is a remote capable emergency light?
It’s a fixture with extra battery capacity designed to power one or more remote emergency lighting heads in addition to its built-in lights.
How many remote heads can one unit power?
It depends on the fixture’s total output and the wattage of each head. Check the unit’s VA rating and calculate how many additional heads it can support.
Where are remote capable units typically used?
They’re ideal for large spaces, stairwells, corridors, warehouses, and multi-level facilities where distributed emergency lighting is needed.
Are these fixtures code compliant?
Yes. Remote capable models are UL 924 listed and meet NFPA 101 requirements for emergency egress illumination.
What’s the advantage of using remote capable fixtures?
They let you centralize battery backup in one location and extend coverage with small remote heads—reducing fixture count and simplifying maintenance.
Can they be used outdoors?
Many models are available with wet-location or NEMA 4X ratings for outdoor or harsh environments.
