1. All eight ACM-8RF relays activated on a single module.
2. All annunciator LEDs on
3. LDM-32F with LEDs on
4. If using the Reverse Polarity Alarm output, add 0.005 amps; if using the Reverse Polarity Trouble output, add
another 0.005 amps.
5. Refer to the Device Compatibility Document for standby current.
6. Must use compatible listed Power Supervision Relay.
7. Maximum alarm current for each sounder base is 0.015 amps which must be supplied by aux. 24VDC source.
8. Current limitation of Terminal TB3 & TB4 circuits is 2.5 amps per NAC.
9. The total standby current must include both the nonresettable/resettable (TB1 Terminals 1 & 2) and resettable
(TB1 Terminals 3 & 4) power. Caution must be taken to ensure that current drawn from these outputs during
alarm does not exceed maximum ratings specified. Current limitations of TB3 & TB4 circuits is 2.5 amps per
NAC output and 0.5 amps per auxiliary power output
10.Total current draw listed above cannot exceed 6.0 amps.

Table 7.3 contains columns for calculating current draws. For each column, calculate
the current and enter the total (in amperes) in the bottom row. When finished, copy the
totals from Calculation Column 2 and Calculation Column 3 to Table 7.4 on page 167.
