OVERVIEW

Hubbell Building Automation’s Enclosed 20 Amp SPDT UL 924

Bypass Relays from Functional Devices, Inc. provide an isolated

N.C. contact that can be used to provide bypass shunt to power

emergency egress lighting directly from the emergency generator

source. The coil in these relays is powered by a normal power supply

and when the loss of commercial power occurs the contact returns

to its Normally Closed state and bypasses controls to the emergency

egress lighting. These fi xtures will remain connected directly to generator

emergency source until transfer back to normal power occurs. An externally

visible LED indicates the generator power source status of the contacts.
