The CAME BPT R/1 Relay Unit is a versatile, high-reliability auxiliary interface designed for intercom and access control systems. It enables seamless integration between low-voltage entry panels/monitors and higher-load peripheral devices, such as electric gate locks, perimeter lighting, or secondary automation equipment. Featuring dual clean (isolated) contacts, the R/1 acts as a switching bridge, allowing an intercom’s auxiliary command signal to safely trigger external hardware. Housed in a compact, DIN-rail mountable module with wide voltage compatibility (8–28V DC / 8–24V AC) and an integrated status LED, it is the essential component for expanding the command capabilities of BPT and CAME entry systems.

The CAME BPT R/1 is a versatile auxiliary relay unit primarily used in intercom and door entry systems. It acts as an interface to bridge low-voltage signals from an indoor monitor or entry panel to higher-load devices, such as electric locks, gates, or other auxiliary equipment.
The R/1 is designed to “multiply” or “strengthen” contacts. For example, if an indoor intercom monitor does not have the power capacity to trigger a heavy-duty electric gate lock directly, the R/1 relay is triggered by the monitor’s low-power signal, which in turn switches the higher-power circuit required to operate the lock.
Two Clean Contacts: Provides two isolated, independent output channels (Double Pole, Double Throw).
Voltage Flexibility: Features an internal jumper switch that allows the unit to operate across a wide range of voltages, making it compatible with various BPT system configurations.
Visual Status: Equipped with an integrated LED that indicates when the relay is active.
Compact Design: Housed in a durable plastic casing that is typically DIN-rail mountable, making it ideal for installation in electrical cabinets or distribution boards.

Lock Control: Triggering magnetic locks or electric strikes from an intercom handset.
Auxiliary Switching: Using an intercom “Aux” button to switch on driveway lighting or secondary gate operators.
Signal Multiplication: Splitting a single command signal to trigger multiple independent devices simultaneously.
⚠️ Installation Tip: The R/1 is a “dry contact” or “clean contact” relay, meaning it does not provide power to the device it is switching; it simply closes a circuit. Ensure that your power supply is correctly sized for the specific lock or device you are intending to drive.
