ALCR-DIN

Automatic Load Control Relay

Overview

The Automatic Load Control Relay (ALCR) is a UL 924 listed device that is powered
from an emergency source and provides power to emergency lighting load(s). The
ALCR ensures a “lights on state” during loss of normal power while tracking the state of
normal lighting loads during normal operation. The ALCR also assures a “lights on”
override by utilizing a normally closed emergency contact closure which interfaces with
fire alarm and emergency systems.

The ALCR is available in two models for installation convenience including Power Pack
(ALCR-PP) and DIN-rail (ALCR-DIN).

Electrical Specifications

Rated for indoor use only. UL, cUL listed Emergency Lighting and Power under
UL 924 at line voltages of 120 and 277 VAC, 60 Hz.

• Load ratings include:

• Ballast loads, 20A maximum at 120 or 277 VAC

• Incandescent loads - 10A maximum at 120 or 277 VAC

• Provides remote activation by dry contact closure for connection to a fire alarm or
building management system.

• ALCR-DIN model only provides auxiliary contact for 0-10 Vdc/ Fluorescent ballasts.

WARNING:

Risk of electric shock! The ALCR utilizes high voltage and should only be
installed by a qualified installer or electrician. Follow all local codes for
installation and follow the proper lockout/tag out procedures per NFPA
Standard 70E.

ETC Installation Guide

Installation Requirements

WARNING:

Important Safeguards

When using electrical equipment always follow basic safety precautions, including:

• READ AND FOLLOW ALL SAFETY INSTRUCTIONS. SAVE THESE

• Install this unit to an approved electrical enclosure only. This emergency device must

• The use of accessory equipment not recommended by the manufacturer may cause

• Do not use this equipment for other than intended use.

Installation

The ALCR-PP (Power Pack) model is designed for permanent installation directly to an
electrical junction box or panel at the electrical lighting load or before the load in the
circuit. Reference "Installation and Termination of the ALCR-PP".

The ALCR-DIN (DIN-rail) model is designed to be permanently installed on a consumer
DIN rail 35mm (complies with DIN43880 and EN60715). Reference "Installation and

Termination of the ALCR-DIN" on page 4.

Note:

Before terminating the AC power wiring verify the breakers for the normal
power and emergency power are in the off position and follow the proper
lockout/tag out procedures per NFPA Standard 70E.

INSTRUCTIONS.

tampering by unauthorized personnel.

an unsafe condition.

The ALCR-DIN must be mounted in a suitably insulated or grounded enclosure,
such that live terminals are not accessible.

Automatic Load Control Relay

Once installation of the Automatic Load Control Relay is complete, reference

"Configuration of Time Delay" on page 6.

Installation and Termination of the ALCR-PP

The ALCR-PP mounts directly to an electrical junction box or electrical enclosure at the
electrical lighting load or before the load(s) in the circuit. The ALCR-PP is fitted with a
1/2” nipple (standard 1/2” knockout).

Two sets of wire bundles are provided on the unit. One set is for emergency power input
and the other set is for sensing normal power. In addition, a single loop jumper is
provided for connection to a remote triggering device (normally closed, maintained dry
contact closure for fire alarms, etc.).

For indoor use only! Must install in an electrical junction box or wire way.
Follow local codes and restrictions.

1/2” threaded nipple. Attach the unit to the junction box.

Note:

Follow all local code requirements for terminating wiring. Notice the harness
wires on the controller unit are pre-stripped for your installation convenience.

Step 4: Connect the Emergency power wiring leads.

a: Connect the Emergency Power In and Power Out wiring leads (Black 12

AWG and Red 12 AWG) on the ALCR-PP with the emergency lighting loads
as shown in the above wiring diagram.

b: Connect the Emergency Neutral (Gray 18 AWG) for the emergency circuit

to the Emergency Neutral lead as shown.

Step 5: Connect the Normal sense wiring leads.

Note:

a: Connect the Normal Power Sense (Black 18 AWG) and Normal Switch

Sense (Red 18 AWG) wiring leads to the normal lighting circuit as shown.

To ensure the emergency lighting in the controlled area turns On in the event
of a power loss, you must connect the Normal Power Sense wires on the line
side of (before) any switched control device for the normal lighting loads.

b: Connect the Normal Neutral (White 18 AWG) lead to the normal Neutral for

the lighting loads.
Step 6: Proceed to "Initial Test" on page 7.
Step 7: If you are installing a remote triggering device to remotely activate the emergency

circuit, refer to "Installing a Remote Activation Input to the ALCR-PP" for wiring
instructions.
