Scantronic ADP-10CC | 10-Zone Wiring Adaptor | Converts FSL to 4-Wire CC

FAQs

What is the difference between FSL and closed circuit zones?

Fully-supervised loop (FSL) zones use end-of-line resistors and specialized wiring topology to monitor circuit integrity, detecting tamper, open circuit, and short circuit conditions through resistance measurement. Closed circuit (CC) zones use traditional 4-wire connections with separate alarm and tamper circuits, representing conventional wiring methods used in older security systems. The ADP-10CC bridges these technologies, allowing 4-wire devices to connect to modern FSL-based control panels without requiring specialized FSL wiring infrastructure.

Which Eaton control panels is the ADP-10CC compatible with?

The ADP-10CC is compatible with Eaton control units featuring 10 on-board FSL zones, specifically including the i-on40H control unit. Other Eaton panels with similar 10-zone FSL architecture may also be compatible, though installers should verify compatibility with specific panel models before specification. The adapter is designed for panels where converting some or all FSL zones to closed circuit operation would benefit the installation, such as when integrating legacy detection devices or utilizing existing 4-wire cabling.

Can I use the ADP-10CC to convert only some zones rather than all 10?

Yes, the ADP-10CC allows flexible configuration where installers can choose which zones to convert from FSL to closed circuit operation. Not all 10 zones need to be utilized as closed circuit; unconverted zones can remain as FSL if the installation benefits from mixed zone types. This flexibility enables optimal system design where some areas use traditional 4-wire devices whilst others utilize FSL wiring, accommodating varied detection requirements and existing infrastructure within a single installation.

Does the ADP-10CC maintain zone supervision?

Yes, the ADP-10CC maintains supervision capabilities when converting FSL zones to closed circuit operation. The adapter preserves the control panel’s ability to monitor circuit integrity, detecting tamper, open circuit, and fault conditions even when using conventional 4-wire connectivity. This ensures the security system maintains full supervision functionality required by professional installation standards and insurance requirements, regardless of whether zones are wired using FSL or closed circuit topology.

When would I use the ADP-10CC in an installation?

The ADP-10CC is valuable in several scenarios: upgrading older systems to modern Eaton control panels whilst preserving existing 4-wire detection devices and cabling; new installations in buildings with pre-installed 4-wire infrastructure where rewiring is impractical; integrating specific detection devices only available with 4-wire connectivity into FSL-based systems; or mixed installations where some zones benefit from FSL whilst others require traditional wiring. The adapter provides cost-effective flexibility without compromising system supervision or functionality.

Where should the ADP-10CC be mounted?

The compact 185 x 150 x 20mm dimensions allow mounting within most control panel enclosures, providing centralized wiring and protection. Alternatively, it can be mounted in separate junction boxes or protected areas near the control panel if enclosure space is limited. The wide operating temperature range (-10°C to +55°C) and humidity tolerance (up to 95%) enable installation in varied locations including plant rooms, cupboards, or loft spaces, though protected mounting away from direct environmental exposure is recommended for long-term reliability.

Does using the ADP-10CC affect system performance?

The ADP-10CC is a passive wiring adapter that doesn’t introduce latency, power consumption, or signal processing into the detection circuit. It simply converts the electrical interface between FSL and closed circuit topologies, maintaining the control panel’s native zone response times and supervision capabilities. System performance remains identical to direct-wired zones, with no degradation in detection speed, false alarm resistance, or operational reliability. The adapter is transparent to both the control panel and connected detection devices.

What happens if the ADP-10CC fails or is tampered with?

Any disconnection, damage, or tampering affecting the ADP-10CC will be detected by the control panel’s zone supervision monitoring, triggering appropriate tamper or fault indications. The supervised nature of both FSL and closed circuit zones means circuit integrity is continuously monitored, ensuring any compromise of the adapter or its connections generates system alerts. Professional installations typically mount the adapter within tampered enclosures, providing additional physical protection and immediate notification if enclosure access is attempted.
