LVS Controls EPC-120V Emergency Power Relay Module
The LVS Controls EPC-120V Emergency Power Control Relay Module provides a straightforward way to manage emergency lighting circuits. Rated at 120V and 20A, it is designed to control up to 20 light fixtures, enabling a regular switch to power emergency lighting during outages. This module is suitable for commercial spaces that require reliable fail-safe operation without complicated wiring.
Key features include: 120 Volt operation, 20 Amp current handling, and the ability to regulate up to twenty fixtures. This makes it a practical choice for small to mid-size commercial applications where a single relay can govern multiple emergency lighting points. The module supports integration with standard electrical control devices, which can simplify retrofits or new installations in offices, schools, or retail environments.
When selecting this relay, ensure the power and load do not exceed the 20A rating and verify compatibility with existing emergency lighting circuits. Proper enclosure and secure mounting are important to prevent accidental contact and ensure long-term reliability in busy electrical rooms or ceilings.
Generic ESRN UL924 Emergency Lighting Relay
The Generic ESRN UL924 Emergency Lighting Relay is designed to support emergency lighting activation during electrical outages. It covers a broad input range, described as 120-277 VAC, enabling versatile use across different building systems. The device carries a 20-amp SPST rating, allowing substantial loads to be managed safely within a single-pole, single-throw configuration. This makes it adaptable for several emergency lighting fixtures or circuits within commercial settings.
Considerations for this relay include verifying UL924 compliance, ensuring the voltage range matches the building’s electrical supply, and confirming the intended load does not exceed the 20A rating. The compact form factor can simplify retrofits in electrical closets or centralized panels. Always follow local electrical codes during installation and use proper wire sizing and protective enclosures to maintain safety and reliability in emergency conditions.
CZSR8001-2A1B3AT1BT Safety Relay Emergency Stop Button
The CZSR8001-2A1B3AT1BT Safety Relay Module combines safety interlock features with a relay suitable for emergency stop applications. While primarily a safety-oriented relay, these devices can be integrated into emergency lighting systems to ensure safe shutdowns or controlled power release in critical scenarios. The product emphasizes solid-state reliability and operation over a wide temperature range, making it suitable for industrial environments that demand consistent performance from -20°C to +60°C.
When evaluating it for emergency lighting control, assess compatibility with existing control circuits, ensure that wiring arrangements support proper actuation without unintended loads, and confirm it meets local safety standards. Its solid-state design can offer faster response times and longer service life in high-use environments, which is beneficial for facilities with frequent power fluctuations or safety-critical lighting requirements.
SOCAL-LED LIGHTING 3-Pin EP28 LED Flasher Relay
The SOCAL-LED LIGHTING EP28 EP-28 is a 3-pin electronic LED flasher relay primarily used to address hyper flash issues in LED lighting and turn signal applications. While not a dedicated emergency lighting relay, it is commonly used in control panels where LED indicators or signaling are necessary. It replaces older stock relays in fuse boxes and offers a compact, plug-and-play solution for compatible 12V LED systems.
Users should verify that the EP28 is appropriate for the intended control circuit and voltage. The compact dimensions (approximately 1.5″ x 1.5″ x 1.5″) mean it may not fit every panel, so checking space and connector compatibility is essential before installation in emergency-related control wiring that must remain secure and reliable during outages.
SOCAL-LED LIGHTING 3-Pin CF13 EP34 LED Flasher Relay
The SOCAL-LED EP34 CF13 is a speed-adjustable 3-pin LED flasher relay with a strobe mode. This module supports adjustable blink rates and strobe features, making it suitable for special-event lighting or signaling within an emergency lighting panel where visual indicators are desired. The unit is slightly larger than standard factory relays, so size compatibility within control boxes should be checked before installation.
For emergency lighting applications, consider whether a flasher relay is needed for indicators or signaling within the system. If standard emergency illumination is the goal, flasher-specific relays may be a secondary option; however, for signaling or show lighting in safety zones, the CF13 EP34 offers flexible control over flash patterns and timing. Ensure proper heat dissipation and secure mounting for long-term use in electrical panels.
SOCAL-LED LIGHTING 4-Pin EP29 LED Flasher Relay
The SOCAL-LED EP29N is a 4-pin LED flasher relay designed to fix hyper-flash issues in turn signal applications and provides a plug-and-play replacement for standard EP-29 flashers. It is commonly used to ensure reliable signaling in emergency vehicle or fleet lighting systems where LED indicators must operate without abnormal rapid blinking. Users should verify socket compatibility and ensure the 12V supply matches the vehicle or panel requirements.
As with all LED flasher relays, proper fitment is essential. Check the mounting depth, connector spacing, and overall dimensions to ensure a snug fit in the control box. For emergency lighting contexts, use this relay only where signaling continuity is required and not as a primary power control for illumination itself.
Buying Guide
When choosing an emergency lighting relay for UL 924 compliance and reliable operation, consider these key purchase factors:
- Electrical ratings: Confirm voltage range and current rating match the building’s lighting load and the intended control scheme. A 120V, 20A relay suits many commercial lighting circuits, while broader voltage ranges support mixed systems.
- UL/CSA compliance: Ensure the relay is certified for emergency lighting applications (UL 924 or equivalent) to meet safety and code requirements.
- Load type and configuration: Decide between SPST, SPDT, and DPST configurations based on whether you need single-pole control or multiple independent circuits.
- Control integration: Assess compatibility with existing switches, relays, or building automation systems. Simple retrofit projects benefit from devices that accept standard wiring and mounting methods.
- Physical size and enclosure: Check the device dimensions and enclosure type to ensure a proper fit in panels, ceiling boxes, or electrical rooms, and verify heat dissipation if loads are near the rating.
- Reliability and operating environment: Look for solid-state designs or components rated for industrial temperatures and frequent cycling, especially in spaces with temperature fluctuations.
- Safety considerations: Ensure proper isolation, wire sizing, and protective housing to prevent accidental contact and to maintain reliability during outages or faults.
- Versatility vs. specialization: For general emergency lighting control, a simple, high-current relay may suffice. For signaling, flasher modules offer added functionality but are not substitutes for primary illumination control.
In summary, the LVS Controls EPC-120V and the Generic ESRN UL924 relay provide solid options for main emergency lighting control with clear current ratings and voltage ranges. The CZSR8001 safety relay adds safety-focused functionality for stop-button integration in complex systems. The SOCAL-LED EP28, EP34, and EP29 modules cater to LED signaling and turn-signal style needs, which can be useful in control panel design or signage-enabled emergency setups. When assembling an emergency lighting solution, ensure that all components meet local codes and that installations prioritize reliability, safety, and clear, maintainable wiring paths.
