The Blue Box LT at a Glance

Three enclosure sizes:

  1. GR1404 - 2 or 4 relays
    (8.4H x 8.4W x 3.125D)
  2. GR1408 - 4 or 8 relays
    (13.4H x 8.4W x 3.125 D)
  3. GR1416 - 8 or 16 relays
    (17.1H x 10.6W x 3.125D)

Two Panel Types:

  1. Master Panel with the Digital Time Clock (DTC), a photocell input and an optional modem. Every system needs one Master Panel.
  2. Remote Panels share the Digital Time Clock (DTC) clock, photocell and modem in the Master Panel.

One Digital System:

Our simple, intuitive network connects multiple Blue Box LTs and switches using Cat. 5 with RJ45s.

Lighting Relays

Our lighting relays are the most robust in the industry, with an SCCR of 18,000a and a duty-rating of over 250,000 throws!

  • 30a @277v (ballast)

The Blue Box LT Series is a cost effective, simple alternative to traditional time clocks, twist timers and contactor packages. It comes in three enclosure sizes, each with a compact footprint. The Blue Box LT Series is ideal for small-to-medium projects, and arrives pre-assembled and ready for installation. The Master Panel may be networked with up to 16 digital devices including Remote relay panels, switches and photocell. The Master Panel has an input for an outdoor photosensor which may be programmed to control any relay(s) on the bus. The Blue Box LT Series is compatible with LC&D’s GR 2400 system
accessories. Blue Box LT remote panels may be used on GR 2400 systems.

The Blue Box LT vs. Lighting Contactor-Panels

Electrical contractors around the country agree: the Blue Box LT beats contactor panels, hands down: competitively priced, pre-assembled, and easy to configure - try the Blue Box LT on your next job.

Lighting Contactors

All Blue Box LTs are UL Listed. Field assembled contactor panels are not usually UL Listed, even if some of the components are.

The Blue Box LT Non Volatile Memory for all programming, 10 year battery back up for the Time of Day. If your client loses power, all schedules will be restored when normal power is restored.

Most clocks use a 24-hour battery. Who does the customer call when the clock loses its schedules after a power outage?

Multiple panels are linked with Cat. 5 cable and share a single clock and photocell. Changing schedules and zoning is simple.

Multiple panels can only be linked to a single time clock with line voltage (and conduit) hard-wiring. Schedule changes or re-zoning may require hard-wire (and hardware) changes.

The Blue Box LT complies with every energy code in the USA and is CEC Certified for Title 24 in California. Field configured panels may require engineering to comply with energy codes, and may not be certified for Title 24.

Link our Digital switches to Blue Box LTs with Cat. 5 cable. On/off control and time clock override all-in-one and control any relay in any panel in any configuration. Programming changes are simple.

Twist timer switches are hardwired to contactors direct or in parallel with time clocks. Manual On/Off switches are also hardwired to contactors in series. Both switches require line voltage, conductor and conduit. Changes may require new hardware and new wiring.

Any relay can be assigned to any lighting zone through simple programming.

Lighting contactors can not be field configured without hard-wire (and hardware) changes.

The DTC Clock in the Master panel has 32 channels, and is a 7-day, 365-day and astronomical clock all-in-one. The only clock you will ever need.

Most commercially available clocks are 2 channels. More schedules require more clocks, usually located in multiple contactor panels.

Make changes to the Blue Box LT remotely (with purchase of a modem) over dial-up. Or call our Technical Support line and have us do it for you for free for the life of the system.

Changes made to lighting contactor panels require you to be on-site.

One photocell can control relays in multiple panels.

Usually a separate photocell is required for each group of contactors in each panel, increasing future on-site maintenance.

Energy Code Compliance
Lighting control panels (with a scheduled automatic shut-off) remain the most cost-effective solution for energy code compliance in common areas (lobbies, hallways), warehouse spaces, site lighting and signage. Use the Blue Box LT on your next project, instead of field-assembled contactor panels. Save time and money and get onto your next job FAST!

Build Your Blue Box LT System

Step 1. Master Panel
Each system needs one Master Blue Box LT
  1. How many circuits (relays) will you need? For more than 16 relays, add a remote Blue Box LT. See enclosure sizes
  2. Do you need a modem for remote dial-up programming?
  3. Do you need a Digital Input Card for occupant sensors, or switches?
complete_digital_bus

Step 2. Add Remote Panels
To control circuits fed from remote breaker panels, consider using multiple (remote) Blue Box LTs. Our intuitive network allows Blue Box LTs to share the time clock and photocell from the master Blue Box LT.

  1. For each additional Blue Box LT, how many circuits (relays) will you need? See enclosure sizes
  2. For each additional Blue Box LT,will you need a Digital Input Card for occupant sensors, or switches?
complete_digital_bus
Step 3.Add Switches, Outdoor Photocells & Accessories
  1. How many override switches do you need? How many buttons on each switch? (1 to 6 buttons cost the same)
  2. Will you need a photocell to supplement the DTC astronomical clock?
  3. Will you need any other accessories?

Ditch the Old Way of Doing Things.
Traditional lighting contactor panels require an electrical-mechanical assembly specific to the job at hand. This means parts/pieces and assembly time. Programming or hardwire changes made to lighting contactor panels require you to be on-site.
