Split Alarm and Selective Silence Applications
5.3 Split Alarm and Selective Silence
Selective silence can only be accomplished if the sync protocol from the FACP is passed through the HPFF8, which is configured for
Split Alarm. The selective silencing is accomplished in pairs of NACs 1&2 and 3&4.
5.3.1 Selective Silence
In this application, the power supply and FACP have been configured for selective silence as illustrated in Figure 5.3. The sync protocol
has to be passed through the HPFF8 from the FACP to selectively silence the NACs. The FACP must be capable of a visual annunciation
to the silencing status of the output or zone(s) to which the HPFF unit(s) are connected.
If the Programming DIP Switches are set as shown below, all four NACs will follow (Pass-through/Slave) the signal from the FACP
including which NAC output pair will be silenced.
Two independent inputs are required for silencing. Two separate addressable modules can be used as shown in Figure 5.2, mounted on
the control board (one on the other) or in a separate UL-Listed panel. Alternately, two outputs of a six-output addressable module can
also be used and mounted on the Control board as shown in Figure 5.4.
Notes for Figure 5.3:
1. When the power supply is in normal/standby state, a trouble will result in an open circuit condition on the control module output
circuit (monitored by the End-of-Line Resistors on TB3). The HPFF’s alarm circuit will always remain closed in the alarm state.
Therefore, the Trouble contacts at TB2 need to be used to report troubles to the FACP during an alarm. See Section 4.1, “Supervised
Functions and Field Wiring”.
2. The FACP NAC outputs must be programmed as a silenceable points and the HPFF8 programmed for Selective/Split Alarm to
allow selective silence of horn/strobe devices.
3. The value of the ELRs (End-of-Line Resistors) on TB3 depends on the FACP used.
4. For a list of compatible devices, refer to the HPP Device Compatibility Document.
5. The same gauge wire must be used if two conductors are connected to the same terminal of any terminal block.
6. Do not complete a continuous circuit around the screw terminal. There must be two separate wires on either side of the screw at the
terminal block. “T-tapping” is absolutely NOT ALLOWED.
