Scantronic FOB-2R-4B | Two-Way Wireless Keyfob | 4-Button Remote, System Feedback, Grade 2

FAQs

What is the advantage of two-way communication over standard one-way keyfobs?

Two-way communication enables the FOB-2R-4B to receive status information from the control panel and provide visual feedback to the user. When you set the system, the keyfob confirms that the panel has successfully armed, eliminating uncertainty about whether the premises are secured. You can also query system status at any time to verify the current armed state without needing to return to a keypad or use a smartphone app.

Why is learning the keyfob to a user profile beneficial?

Traditional wireless keyfobs often occupy radio zones in the control panel, reducing the number of available zones for detection devices such as PIR sensors, door contacts, or glass break detectors. The FOB-2R-4B is learnt to user profiles instead, preserving all radio zones for actual security detection whilst still providing full remote control functionality. This approach maximizes system capability, particularly important in installations approaching zone capacity limits.

What can the programmable output button control?

The programmable output button can be configured to trigger any panel output, commonly used for controlling motorised gates, garage doors, electric locks, security lighting, or other auxiliary equipment. This single keyfob can therefore replace separate gate remotes or access control devices, simplifying user experience whilst maintaining security through encrypted communication. The specific output triggered is configured during system programming to match your installation requirements.

How long does the battery last and can it be replaced?

The FOB-2R-4B uses a single CR2450 lithium battery providing typical operational life of three years under normal usage conditions. The battery is user-replaceable, ensuring the keyfob can remain in service throughout its operational lifespan without requiring return to the installer. Battery replacement involves opening the case and installing a new CR2450 coin cell, a straightforward process for end users or maintenance personnel.

What is the transmission range and how does this compare to standard keyfobs?

The FOB-2R-4B provides 200 meter transmission range in open space conditions, sufficient for operating the system from vehicles parked at residential properties or small commercial premises. Actual range varies depending on building construction, RF interference, and environmental factors, but the specified range typically ensures reliable operation from car parks, entrance gates, or approach roads. This matches or exceeds most standard security system keyfobs.

Is the FOB-2R-4B compatible with older Scantronic panels?

Yes, the keyfob supports both SSR mode (868-868.5MHz) for current Scantronic panels with advanced encryption and two-way features, and legacy mode (868.6625MHz) for backwards compatibility with older installations. The control panel determines which mode is used based on its own capabilities. All current Eaton security control panels support the full SSR feature set including two-way communication and AES128 encryption.

Can multiple keyfobs be used with one control panel?

Yes, multiple FOB-2R-4B keyfobs can be learnt to a single control panel, each associated with different user profiles. This enables individual access control for family members, staff, or authorized personnel, with each keyfob’s activity logged against its specific user profile for audit trail purposes. The number of keyfobs supported depends on the control panel model and available user profiles.

What does EN50131 Grade 2 compliance mean?

EN50131 Grade 2 compliance indicates the FOB-2R-4B meets European standards for security systems protecting against attackers with limited knowledge and tools. Grade 2 is appropriate for residential properties and small commercial premises with low to medium security risk. The keyfob’s AES128 encryption and two-way authentication protocols contribute to this security rating, ensuring transmitted commands cannot be intercepted, replayed, or spoofed by unauthorized parties.
