Radionix D122 Dual Battery Harness with Circuit Breaker

Add parallel battery capacity to a compatible security control panel with a purpose-built harness that joins two batteries while routing the connection through a circuit breaker. Radionix D122 provides the interconnect required where a panel supports two batteries connected in parallel. The harness addresses the battery connection between those batteries and the compatible panel. Parallel battery wiring is relevant when a security system requires two batteries connected to the same compatible panel input. The circuit breaker forms part of the harness, placing protection in the battery connection path. Select D122 when the installation requires a dual-battery harness and the target panel explicitly supports the intended parallel battery arrangement. Maintain the panel manufacturer's required battery wiring and protection practices. This physical security accessory keeps the dual-battery connection as a discrete harness assembly rather than requiring field-built battery interconnects. Its defining characteristics are its two-battery parallel configuration and circuit-breaker-equipped harness construction. Do not substitute ordinary single-battery leads when two batteries must be interconnected at a compatible panel; this harness serves that specific wiring role as part of the security system's battery wiring.
