It provides four supervised audio circuits that can be used for distributed voice evacuation, alert tones, or mass notification messaging. When combined with up to four EVS amplifiers (EVS-50W, EVS-100W, or EVS-125W), the system can achieve a total power output of 500 watts. The EVS-CE4 is fully supervised and mounts directly inside the main FACP cabinet for ease of installation and system integrity. Supporting both System Sensor and SD communication protocols, it integrates seamlessly with existing detection devices to expand coverage and enhance emergency communication capability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFour Supervised Speaker Circuits: Expands the 5820XL-EVS system’s audio distribution for multi-zone voice and tone signaling.\u003c\/li\u003e\n\u003cli\u003eHigh Power Capacity: Supports up to 500W total output with connected EVS amplifiers for large-scale voice evacuation coverage.\u003c\/li\u003e\n\u003cli\u003eFlexible Amplifier Compatibility: Works with EVS-50W, EVS-100W, and EVS-125W amplifier models for scalable system design.\u003c\/li\u003e\n\u003cli\u003eWide Device Support: Integrates with up to 396 SK or 508 SD detection devices using supported protocols.\u003c\/li\u003e\n\u003cli\u003eCompact Cabinet Mounting: Installs directly inside the 5820XL-EVS cabinet to save space and simplify wiring.\u003c\/li\u003e\n\u003cli\u003eEfficient Power Usage: Consumes just 20 mA in standby and 180 mA in alarm mode for low energy demand.\u003c\/li\u003e\n\u003cli\u003eReliable Supervision: Provides complete monitoring of speaker circuits and amplifiers for system integrity.\u003c\/li\u003e\n\u003cli\u003eUL Listed for Safety: Meets UL standards for fire alarm and emergency voice evacuation systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe EVS-CE4 delivers the reliability and precision required for large-scale emergency communication, expanding system audio capacity while maintaining Silent Knight’s standard of safety and performance.\u003c\/p\u003e","brand":"Silent Knight","offers":[{"title":"Default Title","offer_id":49105149133056,"sku":"EVS-CE4","price":571.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0388\/5331\/2557\/files\/evs-ce4_edited.png?v=1785541334","url":"https:\/\/alotechparts.com\/products\/evs-ce4-silent-knight-4-circuit-audio-expander-for-5820xl-evs-fire-alarm-control-panel","provider":"Alo Tech Solutions","version":"1.0","type":"link"}
