If the keypad Type is set to an SDI type keypad (see below) the supervision setting can be configured YES or NO. When the keypad Type is set to one of the SDI2 type keypads the supervision Yes/No setting is ignored and the keypad is supervised.
SDI2 devices are always supervised by design regardless of the supervision setting.
D1255 VFD Keypad (SDI)
D125xRB Keypad (SDI)
D126x LCD Keypad (SDI)
SDI2 devices that are the same type of device must use different addresses.
SDI2 devices that are not the same type can be configured to the same address.
The B915, B92x, B930 or B942 are all same device types (keypads) and must use different addresses.
The B920, B208 and B520 are all different device types and can all use the same address.
