ZIC-4A Bell Follower Circuit Wiring
NOTES
1. All wiring must be in accordance with Article 760 of NEC or local
building codes.
2. Only Zone 1 can be configured as Bell Follower-Primary. Any other
zone can be configured as Bell Follower-Secondary. There can only
be one Bell Follower-Primary per enclosure.
3. Electrical Ratings:
Bell Follower-Primary:
Input Alarm Current: 6mA max
Input Voltage: 24 VDC nominal
No end of line resistor is used.
Bell Follower-Secondary:
Input Voltage: 24 VDC nominal
Output Supervision Current: 4mA max
Output Alarm Current: 3A max
Output Voltage: 24 VDC nominal
4. Bell Follower-Primary is not supervised.
5. Bell Follower-Secondary is supervised for input voltage presence,
short and open on the output and is power limited. Bell Follower-
Secondary can be configured or Class A or Class B wiring.
6. The total output loop resistance must not
exceed those stated in table to the right.
7. Refer to CAB1/CAB1R (P/N 315-0330007) and CAB2-BB/CAB3-BB
(P/N 315-033009) Installation Instructions for details on the
separation of power limited and non-power limited wiring.
8. Positive or negative ground fault detected at <40K ohms for
terminals 1-16.
9. The use of sync strobes is not allowed on the secondary circuits.
