Installing a Remote Activation Input to the ALCR-DIN
The ALCR-DIN offers a normally closed, dry contact input to accommodate connection
to fire alarm panels, security systems, and test switches. This input ships from the
factory with a blue wire loop (jumper) off the bottom screw terminals. This complete loop
disables remote activation.
The remote device that triggers the Emergency circuit “On” must provide a normally
closed, maintained dry contact closure. When the remote device is activated, the
contact closure is opened and the contacts force the ALCR into the emergency “On”
state.
Step 1:
Power up and test your system before installing a remote activation input to your
ALCR. See
"Initial Test" on page 7
.
Step 2:
Remove the factory installed jumper from the Remote Loop In and Remote Loop
Out terminals.
Step 3:
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.
Step 4:
Continue to
"Remote Activation Test"
section on page 7.
Configuration of Time Delay
The Automatic Load Control Relay features a user configurable delay time between
regaining normal power and removing power from the emergency lighting. This delay
time could be used to account for loads that may require a warm up time, for example
HID lamps. The unit ships from the factory configured for 0 delay time. If a longer
transition time is required follow the steps below for configuration:
Step 1:
Press the
[Option Button]
located on the user
interface of the ALCR. Both “Status” and
“Remote” LEDs will blink to indicate the delay
time that is configured.
Step 2:
Press the
[Option Button]
to increment
through the available settings.
Step 3:
When the blink pattern matches your desired
delay time, wait 10 seconds for the operation
to time-out. The delay time setting will be
saved to memory and the ALCR will return to normal operation.
N o t e :
ETC highly recommends that you power up and test your system before
connecting to a remote device.
Do not remove the factory installed jumper unless you are installing a remote
triggering device.
N o t e :
A remote device, such as a test switch or the external emergency system such
as a fire alarm panel or security system must be installed within 1,000 feet of
the ALCR-PP when using 18AWG wire.
N o t e :
The time delay only applies to the main contact on the ALCR. It does not apply
to the auxiliary contact on the DIN rail unit.
