3. Electrical Ratings
24 VDC
Must be power-limited.
Current Draw from 24 VDC Input @ Normal Standby: 0.030 amps
Maximum current with all output relays activated: 158 mA.
Relay Contacts
UL contact ratings are 5 amps @ 125 VAC (resistive) or 30 VDC (resistive)
and 2 amps @ 125 VAC (inductive).
Data Communications Port
Must be power-limited.
EIA-485 operating at: 20 Kbaud
Power Requirements
Each ACM-8RF relay module must be accounted for in the power calculations
outlined in the respective FACP installation manual. The ACM-8RF draws its
power from the control panel and must be considered when calculating the
primary and secondary power supply requirements for the system. However,
if the current draw dedicated to the ACM-8RF must be calculated as a separate
figure (in cases where a separate UL listed power source is used), use the
equations below:
Table 3 Power Requirement Calculations
Standby Current
Number of ACM-8RF modules [ ] X 0.030 = [ ] amps
Alarm Current
1.) Number of ACM-8RF modules [ ] X 0.030 = [ ] amps
2.) Maximum number of relays which
can be activated simultaneously
1
1. The maximum number of simultaneously activated relays depends on system
configuration and programming.
[ ] X 0.016 = [ ] amps
Total Alarm Current (sum of 1 & 2) = [ ] amps
