Overview
The Automatic Load Control Relay (ALCR-DIN) is a UL924 listed device,
powered by a normal/emergency source. The ALCR-DIN tracks the state
of normal power and automatically bypasses control of
the load to the emergency state upon loss of the normal
power sense feed source or when triggered by an
emergency contact closure (for example, a fire alarm). The
ALCR-DIN ensures a lights-on state during loss of normal
power while tracking and matching the control state of
normal lighting loads during normal operation.
The ALCR-DIN provides a relay output that follows the
state of a normal input. Because the output is a relay, the
output side of the ALCR-DIN does not dim, however the
ALCR-DIN can be used in a dimming application when installed correctly
to do so. See Examples of Use on page9 for details. Alternatively, the
ALCR-DIN can be secondarily connected to a 0-10 VDC control source.
Even with external 0-10 VDC control present, in an emergency state the
ALCR-DIN bypasses the external control source and allows the fixture to
switch to its data-loss state (On full).

ETC Installation Guide
ALCR-DIN
Note: The ALCR-DIN does not provide emergency power transfer.
The normal power sense feed allows the ALCR-DIN only to detect
the loss of normal power; it does not connect to the load. In order
to control fixtures that are intended to operate under both normal
power and emergency power, a branch circuit fed from a
normal/emergency panel is required.
Applications that require emergency transfer of single branch
circuits, such as phase-dimmed circuits, should use the ETC
SC1008 branch circuit emergency lighting transfer switch
(BCELTS). For more information, visit the ETC website:
etcconnect.com/SC1008.
Installation Requirements
The ALCR-DIN is designed to be permanently installed on a 35mm

activate the emergency circuit?
• No: Go to Initial Test on page7 to confirm the connection.
• Yes: See Remote Activation Input below for wiring instructions.
7. Restore power to the circuits.
Remote Activation Input
The ALCR-DIN offers a normally closed, dry contact input to
accommodate connection to a fire alarm panel, security system, or test
switch. This input ships from the factory with a blue wire loop (jumper)
connected to two of the top screw terminals. It is a complete loop that
disables remote activation. Do not remove or cut this jumper unless you
are installing a remote triggering device.
Note: ETC recommends that you power up and test your system
before connecting to a remote device. See Initial Test on page7.
The remote device that triggers the Emergency circuit On must provide a
normally closed, maintained dry contact closure for fire alarm systems.
When the remote device is activated, the contact closure opens and the
contacts force the ALCR-DIN into the emergency On state.
Note: The remote triggering device, test switch, or emergency
system must be installed within 305 m (1,000 ft) of the Automatic
Load Control Relay when using recommended1mm2(18 AWG)
wire.
1. Remove the wire loop jumper from the Remote Loop In and Remote
Loop Out terminals.

2. Connect the Remote Loop In and Remote Loop Out terminals on the
ALCR-DIN to the single pole contacts on the remote device or test
switch.
3. Go to Remote Activation Test on page8 to confirm the connection.
Configure a Time Delay
If your lighting requires a warmup period (for example, for high-intensity
discharge [HID] lamps), you can configure a time delay to keep the
emergency lighting on for a period of time after the normal power is
restored. The default time delay is zero. To configure a longer transition
time follow the steps below.
1. Press the [Option] button on the ALCR-DIN. Both the Status and
Remote LEDs will blink to indicate the current time delay
configured.
2. Press and release the
[Option] button to cycle
through the settings, and
stop when the blink pattern
matches the setting you
want.
3. Wait 10 seconds for the
ALCR-DIN to save the setting
and resume normal
operation.
No. of Blinks Time Delay
1 blink no delay
(default)
2 blinks 10 seconds
3 blinks 30 seconds
4 blinks 10 minutes
5 blinks 15 minutes
Note: The configured time delay applies when the ALCR-DIN
senses the loss of normal power and switches to the emergency
state and when the emergency state has been triggered by the
remote activation input.

Power Up and Test
Initial Test
Initial testing of the ALCR-DIN should be done with the Remote Loop In
and Remote Loop Out jumper installed.
1. Turn On the circuit breaker in the emergency panel for the
controlled circuit. The Status LED on the ALCR-DIN illuminates red.
With only the emergency circuit On (normal power should be Off),
the emergency lighting should be activated.
2. Temporarily disconnect and cap the wire lead connected to the
Normal Control Sense input on the ALCR-DIN. This disables the
normal control function and allows exclusive testing of the
emergency On functionality.
3. Turn On the circuit breaker in the normal panel for the controlled
circuit. The Status LED on the ALCR-DIN illuminates green,
indicating that normal power is present and emergency lighting is
not required.
4. Confirm the automatic emergency On functionality by turning Off
the circuit breaker in the normal panel. The connected emergency
lighting should immediately turn On again and the Status LED on
the ALCR-DIN illuminates red.
5. With the normal circuit breaker secured Off, reconnect the Normal
Control Sense wire.
6. Turn On the normal circuit breaker. The ALCR-DIN should now
behave as described in Examples of Use on page9 .
Note: If you have installed a remote activation input to the
Automatic Load Control Relay, see Remote Activation Input on
page5 to confirm proper installation and see Remote Activation
Test on page 8 to test the connection.

Remote Activation Test
With the Remote Activation Input connections made, connected from the
ALCR-DIN and terminated to the single-pole contacts on the remote
device(s) or test switch, test the activation.
• With the remote device in normal mode (contacts closed), the
Status LED on the ALCR-DIN will show green and the device
operates as it did with the factory-installed jumper.
• When the remote device activates, the Status LED shows red,
indicating a switch to emergency state. The ALCR-DIN activates
emergency On mode and the Remote LED shows amber, indicating
remote device control.
Manual Switch Test
The Automatic Load Control Relay features a button to manually switch
the load from normal to emergency power for test purposes.
1. Press and hold the red [Push to Test] button on the front of the
device.
2. Verify the emergency relay closes. This is apparent when the
emergency loads turn on according to your installation.
3. Release the button to return to normal operation.
What does the Test Button do?
The [Push to Test] button simulates the loss of normal power and
bypasses the normal switching of power to the fixture.
