A lighting agency’s line card is stronger when it carries the products that building code typically requires a specifier to buy. Functional Devices, Inc. manufactures UL924-listed emergency lighting relays, UL1008 transfer switches, phase dimmers, power packs, wireless lighting controls, and the RIB® (Relay-In-a-Box®) devices commonly used across building automation.
For an independent agency deciding which lines to represent, our line of RIB® lighting controls pairs demand that already exists with a manufacturer that is straightforward to carry: American-made, tested before it ships, and backed by a support team that a rep can easily reach.
Why a Code-Driven Line Sells Itself
Functional Devices manufactures lighting controls listed to both UL924 and UL1008. UL924 is the product standard for emergency lighting equipment, covering the automatic load control relays and bypass/shunt relays that force a fixture to full brightness when normal power is lost. UL1008 covers transfer switches that move a load from a normal source to a generator or inverter.
When building code and the local Authority Having Jurisdiction determine that a product that is listed to a specific standard must be present in a build, the only open question is which manufacturer’s device gets specified, rather than whether the product itself is necessary in the first place. A rep carrying a strong emergency lighting line is therefore competing primarily on product fit and support.
The Emergency Lighting Line
The ESR series is the core of Functional Devices’s emergency lighting offerings.
The ESRN is a 20 A SPST automatic load control relay accepting universal 120–277 Vac, with a 0–10 Vdc dimmer override, a dry-contact fire alarm interface, and local and remote test capability. The ESRN-U adds SPDT switching and a DALI override for projects on addressable dimming. Where fixture design constrains placement, the ESRB mounts inside the ballast channel, and the ESRLBC uses a slim enclosure suited to linear lighting. For specifications that call for a simpler bypass/shunt device rather than a full ALCR, the ESR2401B (120 V) and ESR2402B (277 V) provide 20 A contacts with UL924 listing.
Where the emergency source is a generator or inverter (a normally-off source), the specification calls for a transfer switch rather than an ALCR. The ESR-BCELTS is a Branch Circuit Emergency Lighting Transfer Switch that transfers a lighting load to an emergency source upon loss of normal power.
The Broader Lighting Line
Emergency lighting anchors the Functional Devices line, but the catalog extends across the rest of a lighting control package.
The LR21F600 phase dimmer accepts a 0–10 Vdc control input across a 120–277 Vac range, rated 600 W at 120 Vac and 1300 W at 277 Vac, with selectable dimming modes. Universal power packs switch lighting circuits from occupancy or daylight sensors while supplying control power, which consolidates devices in a retrofit. The line also includes light controllers, EnOcean energy-harvesting wireless lighting devices for installations where running control wiring is impractical, and step-down transformers. Functional Devices also carries the RIB® Trifecta—relays, current sensors, and power supplies—which gives a lighting-focused agency adjacency into building automation on the same line card.
Why Functional Devices?
American-made, since 1969. Functional Devices designs and manufactures its products in the United States, which affects lead times and supply predictability.
Tested before it ships. Every product is tested before it leaves the facility. Functional Devices reports fewer than one field failure per 16,000 products.
A support team a rep can reach. Functional Devices maintains a tech support and application-engineering team that a rep’s specifiers can consult on device selection and wiring.
Prewired and labeled for the field. ESR series devices come prewired with clearly labeled terminals, which reduces field error on installation.
Frequently Asked Questions
What products would my agency represent?
The Functional Devices lighting controls line spans UL924 emergency lighting relays (the ESR series), UL1008 emergency lighting transfer switches, phase dimmers, universal power packs, light controllers, EnOcean wireless lighting devices, and lighting transformers, as well as the RIB® relay, current sensor, and power supply trifecta used across building automation applications.
Why is emergency lighting a strong category for a rep agency?
Emergency lighting is specified because building code typically requires it, not because a customer necessarily wants it. That makes the demand specification-driven rather than something the rep has to generate.
Does Functional Devices make both UL924 and UL1008 devices?
Yes. UL924 covers the emergency lighting relays that override local controls to bring a fixture to full brightness on power loss; UL1008 covers the transfer switches that move a load to a generator or inverter. Functional Devices manufactures both.
Where are Functional Devices products made?
Functional Devices designs and manufactures its products in the United States and has since 1969.
