1 Main board with display only.
2 If using the Reverse Polarity Alarm output, add 0.005 amps; if using the Reverse Polarity Trouble output, add another 0.005 amps.
3 Refer to the Device Compatibility Document for standby current.
4 Must use compatible listed Power Supervision Relay.
5 Maximum alarm current for each sounder base is 0.015 amps which must be supplied by aux. 24VDC source.
6 When powered by an external source, use 0.040A. When powered by the SLC, use 0.024A.
