A Smarter Way to Install Emergency Battery Equipment
What is AC Activate? AC Activate is an intelligent circuit design that detects the
presence of AC power needed to charge the internal batteries of an emergency
driver. Since the intent of an emergency battery system is to operate a xture
during a loss of normal power, some method of control must be provided so that
the emergency unit can distinguish between an actual loss of power or an unpow-
ered luminaire sitting inside a box waiting to be installed.
Typically, this is achieved through a physical connector between the battery and
charging circuit (often referred to as “go” connectors.) After the xture that is
equipped with an emergency battery is installed, a contractor has to go up into
the ceiling to plug in the go connectors after the building’s electricity is turned on
to allow the emergency battery to begin charging. This task adds an additional
step, and cost, to the install process.
AC Activate technology allows the contractor to make all electrical connections at the
time the luminaire is rst installed regardless of whether the branch circuit will be en-
ergized or not. This feature prevents the contractor from having to visit the luminaire a
second time to mate the battery circuit to the charger.
The Advantages of “Plug and Play” Performance
Once the Switched and Unswitched Input connections are completed to both the xture and emergency
driver, no further connections are necessary. The installed xture can remain in a powered-down state until
AC power is supplied to the circuit or facility. This “Plug and Play” capability of the AC Activate design delivers
several unique advantages over traditional battery packs with physical unit connectors:
Faster / 1X Installation Charge Protection Fixture Integrity Reduced Wiring
Above: AC Activate eliminates the
presence of a physical battery connect, as well as the need to manually
connect the battery at installation.
AC Activate eliminates one
nal step needed at installation. Often, the unit
connectors remain disconnected until AC power
is permanently supplied
to the facility. AC Activate
avoids the need for the
installer to make a second
visit to the xture to complete installation.
If physical battery connectors are mated prematurely
(before AC power is present) the emergency unit will
enter emergency mode and
discharge the battery. The
depleted unit will not be
available for testing by the
AHJ until it has received a
full charge (24 hours after
power is nally supplied.)
In some instances, connecting physical battery
connectors requires the
installing electrician to
access the wiring com-
partment of the xture,
compromising integrity of
the xture and adding the
possibility of inadvertent
damage to xture components or housing.
Servicing Your Emergency Equipment
As always, when servicing a xture equipped with an emergency driver, both nor-
mal and emergency sources should be disconnected to avoid the risk of electrical
shock. With standard emergency products, this is achieved by disconnecting the
battery’s unit connector. Units equipped with AC Activate, the test switch/charge
indicator provides this function: either by simply disconnecting the test accessory
or by pressing and holding the test button for a pre-determined time to activate
the battery’s ‘sleep mode.’ Refer to individual product instruction manuals for
specic details. Once servicing is complete, reconnecting the test switch/charge
indicator and restoring AC power will cause the emergency unit to resume stand-
by mode and continue charge maintenance of the battery.
Eliminating the physical
unit connectors means
less wiring within xture
compartments or junction
boxes. Fewer wires make
it easier during installation when connecting the
normal driver, LED array
and emergency unit in the
xture.

the test switch component of an emergency driver with AC Activate serves as
the unit connector after initialization.
