The system provides a relay contact that can operate a customer-provided alarm, such as a light or bell. The circuitry and power source are customer- provided. The alarm device must not exceed a rating of more than 30 VAC RMS or 60 VDC at 0.75 Amp.

1.Connect an external alarm output through pins 48 and 23 of the AUX connector. See Table 5-6.
