Product Description
ETC ALCR-PP-MK2 Automatic Load Control Relay MK2 - PowerPack version
Part #7180A1215
ETC has introduced a new version of the Power Pack ALCR (Automatic Load Control Relay). The new ALCR-PP-Mk2 model now supports emergency control of 0-10 VDC, DALI, and DMX512 directly controlled emergency luminaires in accordance with 2023 NEC section700.24. When used for emergency control of 0-10V luminaires, these additional relay contacts allow two separate control circuits for luminaires that require two channels of control.
The ALCR allows emergency lighting fixtures that are also used for normal illumination to be controlled under everyday non-emergency circumstances. When normal power is lost or a fire alarm is activated, the ALCR bypasses normal control and forces the emergency lighting fixtures to an emergency state.
Luminaires that are energized to the appropriate emergency level upon loss of control connection are no longer required to be UL 924 listed because of changes to section 700.24 in the 2023 NEC. Unlike the DEBC that actively drives DMX512 channels to full, the ALCR-PP-Mk2 will disconnect 0-10V, DALI, or DMX512 control signals, driving the emergency luminaire to its data-loss state, as well as bypassing any normal line-voltage power control of the luminaire.
The ALCR is a UL 924 Listed emergency lighting device for control of a single, 120/277 V circuit. The ALCR-DIN will remain unchanged from its original version, and will still support a single control circuit of 0-10V or DALI. All new quotes for the ALCR-PP will switch to the Mk2 version immediately. Any existing orders for the original ALCR will continue to ship as the original product. If you would like to change your order to the new version, please contact your customer service rep or project manager.
At ETC, we understand that emergency lighting is first and foremost a matter of life safety. This new version of our Power Pack ALCR will give our customers access to control of many more emergency luminaire types that we weren’t previously able to support.
GENERAL INFORMATION The Automatic Load Control Relay (ALCR) is a UL 924 Listed emergency device that 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. The ALCR is powered from an always-available normal/emergency source fed by an upstream emergency transfer switch or inverter. Both the DIN rail mount model and the Power Pack model support control bypass for 0–10 V luminaires by breaking the 0–10 V control circuit. This will support fixtures that switch to full brightness upon loss of an incoming data signal. The Power Pack model supports a second 0–10 V channel for tunable white fixtures, as well as control bypass for DMX that breaks the control signal in an emergency state. APPLICATIONS • Any lighting control system requiring UL 924 emergency bypass of individual circuits FEATURES • Compatible with 120 V and 277 V power systems • Automatically activates lighting loads upon loss of normal power sense feed source • Provides remote activation by dry contact closure for connection to a fire alarm or building management system • Configurable “return-to-normal” delay of 0–15 minutes • Support for control bypass of connected 0–10 V controlled luminaires (ALCR-DIN and ALCR-PP-Mk2) and DMX controlled luminaires (ALCR-PP-Mk2 only) • Maintenance-free THERMAL • Ambient room temperature: 0°C to 50°C (32°F to 122°F) • Ambient humidity: 10–95% non-condensing REGULATORY AND COMPLIANCE • UL 924 Listed
