Fitting/Replacing the 4-Way Sounder PCB
4
Specification
Outputs:
Sounder PCB outputs:
26 - 28.5V dc
If DIP switch 6 is set to >250mA:
4 x 1A (maximum of 1.5A in total for 2
or more outputs)
If DIP switch 6 is set to <250mA:
4 x 250mA
Digital Inputs:
2 x 5V - 32V dc
Up to two 4-Way Sounder PCBs may be fitted in the panel. If it is
intended to install an 8-way Relay PCB and a 4-way Sounder
PCB, the Relay PCB
must
be in the first (innermost) position.
Each 4-Way Sounder PCB communicates with the PSU PCB via 16-way
ribbon cables in a daisy-chain arrangement.
External power supply unit (if used):
Sounder PCB input: 20-30V dc, 5A
Compliancy: EN54 Part 4 with power status volt-free contact
(normally closed when there are no faults present)
Max Current (per PCB):
Quiescent:
47mA
Alarm/all active: 1547mA
External Wiring
Configurable Circuits
Typical wiring examples are given below. The functions available on a
particular circuit are determined by the configuration options described on
the previous page.
The PCB is supplied with an end-of-line diode across each circuit
connector. Remove these diodes and either (depending upon the usage of
the circuit) place across the end-of-line, or discard if not required in this
usage.
Digital Inputs
Typical wiring examples are given below. The functions available on a
particular input are determined by the configuration options described on
the previous page.
External PSU
If an external PSU is being used, connect the dc input as shown at left, and
the fault input as shown below. Links JP1 and R63 must be set correctly as
described on the previous page.
