1. If using the Reverse Polarity Alarm output, add 0.005 amps; if using the Reverse Polarity Trouble output, add
another 0.005 amps.
2. Refer to the Device Compatibility Document for standby current.
3. Must use compatible listed Power Supervision Relay.
4. Maximum alarm current for each sounder base is 0.015 amps which must be supplied by aux. 24VDC source.
5. Current limitation of Terminal TB1 circuits is 2.5 amps total max.
6. Total current draw listed above cannot exceed 2.7 amps.
