Scantronic KEY-EP | External Proximity (Prox) Reader | Exit Terminate Device, Grade 3

FAQs

Which keypads are compatible with the KEY-EP external proximity reader?

The KEY-EP is compatible with the Eaton Scantronic KEY-KP01 (proximity keypad) and KEY-KPZ01 (proximity keypad with zones). Both of these models feature internal proximity readers and include dedicated connections for adding an external KEY-EP reader. The basic KEY-K01 model does not have proximity functionality and therefore cannot support the KEY-EP. When using the KEY-EP with compatible keypads, both the internal keypad proximity reader and the external KEY-EP reader function simultaneously, providing dual-reader capability for maximum user convenience.

Where should I install the KEY-EP and what are typical applications?

The KEY-EP should be installed at locations where users need convenient proximity tag access before reaching the main keypad. Common applications include mounting at vehicle height for drive-up access in residential driveways or commercial parking areas, positioning at external gates or doors while keeping the main keypad protected indoors away from weather exposure, installing at reception areas or visitor entry points separate from staff keypad locations, placing at multiple entry doors in commercial premises where each access point needs tag reader functionality, and mounting at wheelchair-accessible heights where the main keypad location may not be ideal. The weatherproof design allows outdoor mounting in exposed locations.

Can I use multiple KEY-EP readers with a single keypad?

The KEY-KP01 and KEY-KPZ01 keypads typically support one external KEY-EP reader in addition to their internal proximity reader, providing dual-reader functionality. If your installation requires proximity readers at more than two locations, you would need to either install multiple keypads throughout the premises (each with its own internal reader and optional KEY-EP), or use proximity-enabled keypads like the KEY-KP01 or KEY-KPZ01 at the required locations. The number of keypads and readers you can install depends on your control panel’s bus capacity – for example, the 80HE supports up to 20 bus devices total, which can include multiple keypads.

How does the KEY-EP connect to the keypad?

The KEY-EP connects to compatible keypads via a simple wired connection using the external proximity reader terminals provided on the KEY-KP01 and KEY-KPZ01 keypads. The connection typically requires a multi-core cable run from the keypad location to the KEY-EP mounting position, carrying power and data signals. The cable length is limited by voltage drop and signal integrity considerations – installers should consult the installation manual for maximum recommended cable lengths. Once connected and programmed, the KEY-EP operates seamlessly alongside the keypad’s internal proximity reader with no additional user configuration required.

What proximity tags and cards work with the KEY-EP?

The KEY-EP works with the same proximity tags and cards supported by the Eaton Scantronic system’s internal proximity readers. This includes standard proximity fobs, cards, and keyrings that are enrolled in the control panel’s user database. Each user can have their proximity tag programmed with specific access rights, arming/disarming permissions, and partition access as required. The same proximity tag will work with both the internal keypad reader and the external KEY-EP reader, so users don’t need separate tags for different reader locations. Tags can be easily added, removed, or reprogrammed through the control panel’s user management functions.

Is the KEY-EP weatherproof and what are the environmental specifications?

Yes, the KEY-EP features a weatherproof design specifically intended to allow outdoor installation in exposed locations. This makes it suitable for mounting at external gates, driveways, vehicle access points, and outdoor entry doors where the reader may be exposed to rain, humidity, and temperature variations. The weatherproof construction protects the internal electronics while maintaining reliable proximity tag reading performance in outdoor conditions. However, installers should still follow best practices such as mounting the reader in locations with some weather protection where possible, ensuring proper cable sealing at entry points, and avoiding locations with extreme direct sun exposure or standing water accumulation.

Does using the KEY-EP affect the security grade of my system?

When properly installed with compatible EN50131 Grade 2 certified keypads and control panels, the KEY-EP maintains the system’s security certification. The external reader communicates through the certified keypad, which handles all security-critical functions including encryption and authentication. Installers must ensure the KEY-EP is mounted securely with appropriate tamper protection, cable runs are properly protected against interference or cutting, and the reader location doesn’t create security vulnerabilities such as allowing unauthorized access to building entry points. When installed according to manufacturer guidelines and relevant security standards (PD6662:2017, BS8243), the KEY-EP integrates seamlessly into Grade 2 installations.
