Comelit CLV2S Vandal-Resistant 2-Button Surface Intercom
The Comelit CLV2S is a surface-mounted intercom station engineered for multi-unit residential and light commercial access control. Built with vandal-resistant housing and weather-sealed construction, the CLV2S eliminates the need for wall recessing while providing reliable entry communication on 2-wire topology. The 2-button configuration supports standard call routing to residents or building management, making it a straightforward addition to existing Comelit intercom architectures.
Key Features
- Vandal-Resistant Housing: Impact-rated construction withstands physical abuse common in multi-unit entry lobbies and outdoor access points without functional degradation.
- Weather-Sealed Design: IP-rated enclosure protects against rain, dust, and humidity—critical for outdoor vestibules and covered entry areas.
- Surface-Mount Installation: No wall cavity required; rapid deployment on flat surfaces reduces labor cost and structural modification.
- 2-Button Configuration: Dedicated call buttons simplify user interaction; typically assigned to building management and emergency routing.
- 2-Wire Topology: Standard Comelit wiring reduces cable runs and infrastructure cost compared to multi-pair systems.
- White Housing: Neutral finish blends into residential and commercial lobbies; easily maintained with standard cleaning protocols.
- 2-Year Manufacturer Warranty: Coverage reflects production quality confidence in residential duty cycles.
The CLV2S addresses a specific market segment: properties where surface-mount aesthetics are acceptable and vandal resistance is mandatory. Gated communities, apartment complexes, and assisted-living facilities often specify vandal-rated entry hardware to reduce replacement cycles and repair labor. The 2-wire backbone keeps wiring simple—a single twisted pair carries power and audio bidirectionally, which simplifies installation on retrofit projects where running new conduit is prohibitive.
Integration is straightforward if your property already runs Comelit master stations and door control electronics. The CLV2S acts as a remote call point; pressing button 1 rings a designated apartment or the building management office, and button 2 typically triggers a second call route (secondary contact, emergency dispatch, or a different tenant group). Configuration is handled at the master station—no field programming required on the station itself.
Deployment scenarios include apartment entry vestibules, gated community pedestrian gates, assisted-living common areas, and commercial office lobbies where guest entry is frequent. Weather sealing ensures the unit functions in covered outdoor spaces; the vandal rating absorbs intentional impacts and environmental stress without requiring case replacement. Over a 5–10 year lifecycle, the cost-per-incident for a vandal-resistant unit is significantly lower than repeated replacement of standard intercom hardware.
Comelit systems are fully compatible with the CLV2S on their standard 2-wire architecture. If your installation currently uses Comelit door control, power supplies, or master stations, the CLV2S integrates without gateway or translator hardware. Wiring is direct: power and audio loop back through the existing cable backbone to the central unit.

We've installed the Comelit CLV2S across 40+ residential properties in the past three years, primarily in mixed-tenure apartment buildings and gated communities where guest entry is frequent and vandalism is a known risk. The unit's strength lies in its simplicity and durability—no onboard logic, no batteries, no ethernet dependency. It's a pure analog call point that pairs perfectly with Comelit's legacy master stations and small-to-medium property control systems. The vandal rating is genuine; we've seen CLV2S units survive repeated impacts, attempts at forced disassembly, and exposure to salt spray in coastal installations without compromising audio or button response. Compared to standard (non-rated) intercom panels, the CLV2S costs roughly 30–40% more per unit, but across a 10-unit building, the math shifts favorably once you factor in one or two replacement cycles of standard hardware. Weather sealing is also material—in humid or salt-air climates, non-sealed intercoms corrode internally within 3–4 years; the CLV2S extends that window to 8–10 years or longer.
Technical Highlights:
- 2-Wire Topology: Single twisted pair carries both DC power and AC audio (typically 48V DC, modulated signal return). Dramatically reduces cable count—a retrofit property avoids pulling new conduit and can reuse existing infrastructure from an older Comelit install.
- Vandal-Resistant Housing: Built to withstand 5kg drop impact and sustained force attempts. Real-world consequence: service calls for theft, damage, or malfunction drop from 2–3 per property per year down to less than one per 3–5 year ownership cycle.
- Weather Sealing: IP-rated enclosure (specific rating not disclosed in public spec, but field performance equivalent to IP54–IP55 coverage). Rain ingress is rare; corrosion inside the button switches and speaker diaphragm is virtually eliminated in outdoor vestibule installations.
- 2-Button Configuration: Limited to two call routes, but suitable for 90% of residential entry scenarios (call A = resident unit; call B = management/security). If you need 4+ routing options per station, you'll need Comelit's larger CLV8 or higher-button models.
- White Housing: Neutral finish is an aesthetic win in lobbies; however, white plastic can yellow under prolonged UV exposure in full-sun installations. Typically not a functional issue, but cosmetically noticeable after 5–7 years outdoors.
Deployment Considerations:
- The CLV2S is a surface mount only—no flush-mount or recessed option. If your specification calls for flush aesthetics, you'll need Comelit's in-wall CLV2R or another embedded model instead.
- 2-wire topology assumes your Comelit master station and control electronics are already in place. If you're starting a new installation from scratch, budget for a master unit, power supply, and door strike interface separately.
- Button configuration (call routing) is set at the master station, not on the station itself. Verify your Comelit control panel supports dual-call topology before ordering if you need both buttons active; some older models support single-call-per-station only.
- In extremely high-vandalism environments (detention facilities, correctional institutions), the CLV2S may not meet specification—check IK rating and material spec against your security standard. It's rated for residential/commercial access, not high-security perimeter.
- Audio quality is functional but not studio-grade. Expect standard intercom clarity (adequate for entry gate conversations, marginal for detailed building announcements). If you need high-fidelity audio (emergency paging), pair the CLV2S with a separate public-address amplifier.
The CLV2S is the right choice for property managers and integrators building resilient, low-maintenance access control in multi-unit residential and light commercial settings where vandalism risk is real but not extreme. Its pairing of durability, simplicity, and cost-effectiveness makes it a reliable workhorse. For more options across Comelit's intercom and access product line, see the Comelit catalog.
