Generator Products

Generators are often employed to back up the normal power supply for important systems, such as lighting. Philips Emergency Lighting offers distinct products created to work with generators: GTD Generator Transfer Devices and BLCD-20B Emergency Lighting Control Unit for interim illumination.

Transfer Units & Control Devices
The GTD and BLCD-20B work in conjunction with a generator or central inverter system to supply emergency lighting regardless of local light switch position. This means emergency lighting is no longer dependent on expensive night lighting. In fact, you can switch off normal lighting at the end of the day or whenever it’s not needed without jeopardizing emergency lighting operation. These energy-saving devices sense the loss of normal power and, in response, switch the lighting load to a generator- or inverter-fed circuit.

Transfer Units & Control Devices
Model Function

GTD

GTD

Function: Transfer Device
Lighting Load : 3A max forfluorescent and LED

The GTD operates as a transfer device and functions by transferring both the hot and the neutral. It is designed for areas in which only one fixture may be needed for egress lighting, such as a stairwell or classroom, or in areas where multiple switches are in use. The GTD supports a lighting load up to 3A.

BLCD-20B

BLCD-20B

Function: Control or Bypass Device
Lighting Load : 20A max for fluorescent and LED; 10A max for incandescent

The BLCD-20B operates as a control or bypass device. The small (1.7” x 2.97” x 1.64”), easy-to-install unit mounts directly onto a junction box and supports a lighting load up to 20A. The BLCD-20B features auto-select to automatically select the correct voltage (120/277V) and offers a remote testing capability that permits it to interface with fire alarms and security panels.

BLCD-20X2

BLCD-20X2

Function: Automatic Load Control Relay
Lighting Load: Maximum Lighting Load of any 20A

UL924 Emergency Lighting Compliant Automatic Load Control Relay works with a generator or central inverter system to supply power to designated loads regardless of wall switch position. The BLCD-20X2 allows multiple application and wiring options, including wiring schemes for both line and low voltage dimming. It features universal input and supports a maximum lighting load of 20A.

GTD20A

GTD20A

Function: Transfer or Bypass Device
Lighting Load: 20A max for fluorescent, incandescent, HID and LED

The GTD20A Relay Control Device, like the GTD and BLCD-20B, works with a generator or central inverter system to supply power to designated loads. It functions as a transfer or bypass device and may be installed in areas where a number of fixtures are used and are controlled with a single switch. The device senses the loss of normal power service to the fixtures and immediately switches the load to designated alternate circuit. The GTD20A allows multiple application and wiring options, including wiring schemes for both line and low voltage dimming. It features universal input and supports a maximum lighting load of 20A. The GTD20A is classified under Optional Standby Systems (NEC Article 702).
