Scantronic KEY-2R-KPZ | Wireless Proximity (Prox) Keypad with 2 Zone Inputs | Grade 2

FAQs

What is the difference between this radio keypad and a wired keypad?

The KEY-2R-KPZ offers the same complete functionality as a wired keypad, including full system configuration, arming/disarming, and user menu access, but without requiring cable runs to the control panel. This provides significant installation advantages: you can place the keypad in the optimal location for user convenience without being constrained by wiring routes, it’s ideal for retrofit installations or locations where cabling is difficult or impossible, and it enables tidier installations without visible cables. Despite being wireless, the two-way SSR communication ensures the same reliability and responsiveness as wired keypads, with the added benefit of over-the-air firmware updates.

How does Scantronic Secure Radio (SSR) improve security and reliability?

SSR technology provides multiple advantages over traditional one-way radio systems. The advanced two-way communication means the keypad and panel continuously confirm signal receipt, ensuring commands are executed and status updates are accurate. True signal encryption provides market-leading cybersecurity, preventing signal interception or replay attacks. The shortened device response times mean faster feedback to users and improved battery efficiency. Over-the-air updates keep the keypad secure with the latest firmware without requiring site visits. The bidirectional communication also enables the panel to monitor keypad health and battery status, alerting users before batteries need replacement.

What are the two wired zones on the keypad used for?

The two wired zone inputs integrated into the KEY-2R-KPZ allow you to connect traditional wired sensors directly to the keypad, which then transmits their status wirelessly to the control panel. This is particularly useful for protecting the immediate area around the keypad, such as the entry/exit door where the keypad is mounted. For example, you could connect a door contact to one zone and a PIR covering the entry area to the second zone, creating a complete entry point protection solution with minimal wiring. This hybrid approach combines the installation flexibility of wireless communication with the reliability of wired sensor connections at critical points.

How are the A, B, C, D keys configured and what can they control?

The four programmable setting keys (A, B, C, D) provide customizable quick-access functions that can be configured by the installing engineer to match the specific system architecture and user requirements. Each key can be programmed to arm individual wards in partitioned systems, activate specific partitions for multi-area control, engage part-sets for partial system arming, or trigger programmable outputs for automation or integration purposes. The built-in status LEDs next to each key provide instant visual feedback on the armed/disarmed state of the associated area or output. This flexibility makes the keypad suitable for simple single-area systems through to complex multi-partition installations.

What does backward compatibility with legacy Scantronic radio products mean?

Backward compatibility means the KEY-2R-KPZ can operate in legacy mode (868.6625MHz) to work with older Scantronic radio systems that don’t have SSR technology. This protects your investment if you’re upgrading or expanding an existing system, as you can add new SSR keypads alongside older radio devices without requiring a complete system replacement. When connected to SSR-enabled panels like the 80HE, the keypad automatically operates in SSR mode (868-868.5MHz) with full encryption and two-way communication benefits. This dual-mode capability provides maximum installation flexibility across Eaton’s entire product range.

What is the expected battery life and what affects it?

Battery life for the KEY-2R-KPZ depends on usage patterns and environmental factors. The SSR technology’s shortened device response times significantly improve battery efficiency compared to older radio systems. Factors affecting battery life include: frequency of keypad use, display backlight activation, number of proximity tag presentations, ambient temperature (batteries perform better in moderate temperatures), and signal strength to the panel or expander. The two-way communication enables the control panel to monitor battery voltage and alert users well in advance when batteries need replacement, preventing unexpected battery failures. The keypad uses standard AA batteries for easy replacement.

Can multiple KEY-2R-KPZ keypads be used on the same system?

Yes, multiple KEY-2R-KPZ keypads can be learned into the same system, providing keypad access at multiple locations throughout the premises. This is particularly useful for larger properties, multi-floor buildings, or installations where users need convenient access points in different areas. Each keypad can be assigned to specific partitions if using a partitioned system, or all keypads can have full system access. The wireless installation means you can place keypads exactly where needed without cable routing concerns. The number of keypads supported depends on the control panel model – for example, the 80HE supports up to 20 bus devices total, which can include any combination of wired and wireless keypads.
