Introduction to the CDVI T290‑SR1024 and its key features

CDVI T290‑SR1024 — Symmetrical fail‑secure mortice electric strike (10–24 V)

The CDVI T290‑SR1024 is a compact, reversible mortice electric strike designed for access control systems where security must be maintained in the event of a power failure. Supplied with a robust 306 stainless‑steel T290 faceplate, the unit combines a slim profile with features that improve reliability and compatibility in commercial, public and residential installations. Key highlights include fail‑secure operation, a wide 10–24 V AC/DC operating range, an adjustable radial jaw for tolerance compensation, and built‑in surge protection for enhanced longevity with modern access control panels.

• Fail‑secure operation: remains locked without power and releases when voltage is applied — ideal where doors must remain secure on power loss.
• Wide voltage compatibility: accepts 10–24 V AC or DC, with continuous rating guidance for 12 V in CC mode.
• Adjustable jaw with approximately 4 mm radial play to accommodate latch and tolerance variations.
• Integrated surge/spike protection (bi‑directional diode and MOV/transil) to protect both the strike and access control electronics.
• Symmetrical, reversible body and slim mortice design suitable for left or right hinged doors and many multipoint UPVC systems.
• Durable 306 stainless‑steel faceplate (T290) for strength and corrosion resistance in demanding environments.

Detailed specifications and benefits

The T290‑SR1024 couples technical specification with pragmatic benefits intended for installers, specifiers and building managers. Below are the key specification areas and why they matter in real installations.

• Voltage:10–24 V (AC/DC). Continuous rated at 12 V in CC mode — this wide voltage range makes the strike compatible with many power supplies and access control panels, reducing the need for additional transformers or conversion modules.
• Current consumption:Typical values are ~235 mA @ 12 Vdc; ~200 mA @ 12 Vac; ~470 mA @ 24 Vdc; ~400 mA @ 24 Vac. Understanding these values helps you size power supplies and fuses correctly.
• Protection:Built‑in bi‑directional diode and MOV/transil provide surge and spike protection — valuable when using long cable runs or in electrical environments prone to transients, and it helps protect sensitive access control electronics.

• Holding force:Approx. 280–325 kg (variant/region dependent). This provides a strong secure lock against forced entry when properly fitted to compatible frames and keeps.
• Jaw adjustment:Approx. 4 mm radial play (adjustable) — this adjustability compensates for latch misalignment and seal compression, reducing the need for precise machining during installation.
• Reversibility:Symmetrical body makes the strike reversible for left and right hinged doors, streamlining stocking and installation for mixed‑direction projects.
• Cycle life:Typical tested durability ~300,000 cycles — suitable for medium to high traffic doors when used within its rated conditions.

• Faceplate material:306 stainless steel (T290 faceplate) — corrosion resistant and robust enough for exterior or coastal installations when combined with suitable frame materials.
• Dimensions:Faceplate 250 × 25 × 3 mm; strike body approx. 67 × 22.5 × 28 mm — slim mortice profile ideal for narrow frame cavities and many UPVC multipoint keeps.
• Weight:Approx. 0.18–0.25 kg depending on configuration.
• Operating temperature:Approx. −10 °C to +40 °C (some references list −15 °C to +60 °C). Check the datasheet for the exact variant used in your region.

• Supplied with a durable T290 faceplate that simplifies faceplate alignment and offers a neat finish for mortice installations.
• Symmetrical reversible body reduces the need to stock separate left and right versions — lowers inventory cost and simplifies on‑site choices.
• Integrated surge protection reduces field failures associated with voltage transients, improving mean time between failures when paired with modern controllers.
• Always consult the official CDVI datasheet for exact cut‑out dimensions, wiring diagrams and certified holding forces. Installation should be carried out by qualified technicians, and power isolated before wiring.

Use cases and scenarios where the product excels

The CDVI T290‑SR1024 is designed for applications that demand a slim profile, reliable holding force and secure fail‑secure behaviour. Typical use cases include:

• Commercial office entrances:Exterior doors that must remain locked during a power outage (fail‑secure). The strike works well where access control systems (card readers, PIN pads) release the door only when authorised.
• Public buildings and controlled access points:Doors in libraries, municipal buildings or administrative areas that balance public access with security requirements.
• Multipoint UPVC doors:Slim mortice profile and reversible design make it a good fit for UPVC multipoint systems where recessed strike space is limited.
• Server rooms and secure cabinets:Wherever fail‑secure operation is required to keep critical areas locked if power fails (combined with emergency egress planning).
• Retrofitting and mixed hinge installations:Reversible symmetry and adjustable jaw ease retrofit work on doors of differing handedness and varying latch tolerance.

Comparisons with similar products in the market

When specifying an electric strike, key decision points include fail‑secure vs fail‑safe operation, physical profile (mortice vs surface), voltage compatibility, integrated protection and holding force. The T290‑SR1024 compares favourably in several of these dimensions:

• Fail‑secure vs fail‑safe:Unlike fail‑safe strikes (which unlock on power loss), the T290‑SR1024 is fail‑secure. That distinction is crucial for perimeter doors, server rooms or other areas that must remain locked during power outages. Project requirements and life safety codes will determine which mode is appropriate.
• Slim mortice profile:Many strikes are bulkier or intended for standard steel frames. The T290‑SR1024's narrow body and thin faceplate make it better suited to UPVC and narrow frame cavities where space is limited.
• Voltage flexibility:The wide 10–24 V AC/DC operating range improves compatibility with existing access control systems compared with strikes that accept only a single voltage. This reduces the need for additional power supply upgrades.
• Built‑in surge protection:The integrated diode and MOV/transil set the T290‑SR1024 apart from basic strikes that rely entirely on upstream protective devices — this is a pragmatic advantage in installations with long cable runs or noisy electrical environments.

Customer testimonials and installer feedback

No official customer testimonials were provided with the product information. However, based on typical installer and integrator feedback for strikes with this feature set, common points of praise and constructive notes often include:

• Positive — compact and reversible:Installers frequently appreciate the compact, reversible body that reduces the need to stock multiple handed parts.
• Positive — reliable in access control systems:Integrators often note that built‑in surge protection reduces nuisance failures when the strike is paired with modern controllers.
• Constructive — verify hold and approvals:Specifiers remind purchasers to confirm the exact holding force, environmental ratings and regional approvals (CE / UKCA) for the SR1024 variant being installed.

Example (anonymised) installer impressions described in general terms:

• "Compact unit — easy to fit into narrow UPVC keeps and reverses quickly for both left and right doors."
• "The integrated surge protection is a bonus on long cable runs; we’ve had fewer dash failures compared with earlier strikes."
• "Always check the datasheet for cut‑out dimensions — small differences can complicate retrofits."
