Power Up and Test
Initial Test
Initial testing of the ALCR function should be done with the Remote Loop In and
Remote Loop Out jumper installed on the ALCR-DIN and the blue loop uncut on the
ALCR-PP.
Step 1:
Turn On the circuit breaker in the emergency panel for the controlled circuit. The
“Status LED” on the ALCR will illuminate red. With only the emergency circuit On
(normal power should be Off) the emergency lighting should be activated “On”.
Step 2:
Temporarily disconnect and cap the wire lead connected to the Normal Switch
Sense terminal on the ALCR. This disables the normal control function and allows
exclusive testing of the emergency On functionality.
Step 3:
Turn On the circuit breaker in the normal panel for the controlled circuit. The
“Status LED” on the ALCR illuminates green, indicating that normal power is
present and emergency lighting is not required. The emergency output should be
Off.
Step 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 will illuminate red.
Step 5:
With the normal circuit breaker secured Off, reconnect the Normal Power Switch
wire to the terminal.
Step 6:
Turn On the normal circuit breaker. The ALCR should now behave as described
in the
"Examples of Use" on page 8
.
Step 7:
If you are installing a remote activation input to the ALCR, refer back to the
appropriate section for instructions to complete the wire terminations. Reference
"Installing a Remote Activation Input to the ALCR-PP" on page 4
or
"Installing a
Remote Activation Input to the ALCR-DIN" on page 6
.
Remote Activation Test
Step 1:
Connect the Remote In and Remote Out terminals on the ALCR to the single pole
contacts on the remote device or test switch. Reference or
"Installing a Remote
Activation Input to the ALCR-DIN"
. With the remote device in normal mode
(contacts closed) the “Status LED” on the ALCR illuminates green and the unit
operates as it did with the factory installed jumper.
Step 2:
When the remote device activates, the “Status LED” will illuminate red, indicating
a switch to emergency state. The ALCR activates emergency On mode and the
“Remote LED” illuminates amber, indicating remote device control.
Local Test Button
The Automatic Load Control Relay features a local button that allows manual switching
of the load from normal to emergency power for test purposes.
Step 1:
Press and hold the
[Press to Test]
button located on the front of the unit.
Step 2:
Verify the emergency relay closes, this is apparent when the emergency loads
illuminate according to your installation.
Step 3:
Release the button to return to normal operation.
