Lighting Controls

Our Emergency Bypass/Shunt Relays are UL924 listed and suitable for shunting around wall switches or lighting controls in order to turn on emergency lighting in the event of loss of normal utility power.

When normal power is present, the ESR relay coil is activated and the emergency panel is fed from normal power. The lighting load can be switched on/off using an individual wall switch.

When normal power drops out, the ESR coil is deactivated and N/C contact falls closed. The automatic transfer switch changes over to backup (generator) power, and the lighting load is illuminated regardless of the position of the wall switch.

The Latching Series comes prepackaged in their own NEMA 1 plastic enclosure with a 1/2" mounting nipple, LED indicator and pre-wired for a money-saving installation that is easy and quick. These relays are activated by pulse commands from a controller. The relay contacts are mechanically latched in the closed position and the load will remain on in the event of a control panel failure period. If power is completely lost the contacts will remain in their last state and the load will activate upon the return of normal power or emergency power.

EnOcean® enabled wireless relay receivers in both 120 and 277 Vac models work in conjunction with many switching devices that are EnOcean® enabled with 315 MHz transmitters. Wireless wall switches, occupancy sensors, thermostats, key card switches, patio door switches, and one-way controller transmitters are all devices which can activate Functional Devices' wireless control relays by using EnOcean®'s "energy harvesting" technology. Energy harvesting refers to the process by which energy is captured and stored, then used to transmit a wireless signal, which in turn is received by Functional Devices' wireless relay.

Functional Devices' prepackaged extended range wireless models can be ordered in many configurations. Whether your application calls for simply extending your network using just a single Server and Client transceiver configuration or your application demands a point to multi-point configuration, Functional Devices can meet your requirement with the perfect combinations to provide seamless plug-and-play wireless communications.

Our Closet Light Controllers are designed for a wide variety of applications where the load status (ON/OFF) is determined by the opening or closing of a variety of switches, such as door jam switches, ball switches or magnetic contact switches. These relays are powered by line voltage and can switch loads varying from 120 Vac to 277 Vac.

The PWH24V500A and PWH24V300A are UL Listed, Class 2 Power Supplies, tailor made for centralized power supply to many individual circuits. These packages provide 5 or 3 isolated individual 100 VA, 24 Vac outputs with circuit breaker protection and on/off switches. The primary of these power supplies is multi-tap at 480, 277, 240, and 120 Vac for versatility on many applications.
