Controlling Four NACs With One Input and Selective Silence
Applications
FCPS-24FS PN 51883:B 12/04/02
27
Notes: The following notes apply to Figure 5.1 on page 26.
1. When the FCPS-24FS power supply is in an inactive state (control module not
active), a trouble on the power supply will result in an open circuit condition on
the control module output circuit (monitored by End-of-Line Resistor across
TB4, Terminals 5 & 6). As an alternative, the trouble contacts at TB5 of the
power supply can also be used for independent trouble monitoring.
2. The addressable relay module must be programmed as a silenceable point at the
FACP to allow selective silence of horn/strobe devices. The Normally Open
contact of the relay module is connected between TB4 Terminal 7 (IN2 +) and
Terminal 9 (Aux. Power +).
3. Do not loop wires under screw terminals. Break wires to maintain proper
supervision.
4. An End-of-Line Resistor must be installed between TB4, Terminals 5 & 6 for
control module wiring supervision (the ELR value is dependent on the module
employed).
5. Supervise the power wiring between the FPCS-24FS auxiliary 24 VDC output on
TB4, Terminals 9 & 10 with an EOL relay (P/N: A77-716B)
6. For a list of compatible devices, refer to the Device Compatibility Document.
7.
IMPORTANT!
When the power supply is programmed for both
Selective
Silence
and
Slave Mode
, TB4 Terminal 7 (IN+) must be jumpered to Terminal 9
(AUX+) and Terminal 8 (IN-) must be jumpered to Terminal 10 (AUX-). The
FACP will control the Selective Silence feature with this configuration.
If the terminals are not jumpered as indicated, the horn portion of the horn/
strobes will be silenced at all times.
