External Signal Selection Model (M2BJ-BH24D-DA) An external signal selection model is also available. With this model, it is possible to switch between continuous and intermittent sound using an external signal instead of the jumper. M2BJ-BH24D-DA Switch direction Sound When switch A is ON B Intermittent beeps (when terminals 1 and 2 are ON) SW A When switch B is ON Continuous beep (when terminals 2 and 3 are ON) Note: 1. Ensure that voltage is not applied simultaneously between terminals 1, 2, and 3. 2. Check the power supply polarity. Connecting with the polarity reversed may result in damage. 2 123
