Honeywell Fire-Lite FL-PS10 - Cascading Multiple Units

18 FL-PS Series Instruction Manual — P/N LS10227-001FL-E:B 3/29/2021
Installation Cascading Multiple Units
2.8 Cascading Multiple Units
Up to four FL-PS power supplies can be cascaded together to provide additional NAC extenders for a system. Maintain separation of
power-limited and non-power-limited wiring as shown in Figure 2.6 on page 15.
Figures 2.11 and 2.12 show the controlling signal connected to Input 1 of FL-PS1. However, typically any available Input of FL-PS1 can
be used.
Figures 2.11 and 2.12 show NAC7 of FL-PS1 - FL-PS3 as the cascading output. However, any available Output of FL-PS1 – FL-PS3 can
be used.
The following notes apply to Figure 2.11.
1. Set all FL-PS units to Slave (sync follower) mode.
2. The debounce/dejitter setting must be set to 1 msec on all cascaded units. See Table 3.3 on page 23.
3. Any output used for remote sync applications cannot have notification appliances installed on the same circuit.
4. Notification appliances cannot be installed on the interconnecting control circuits.
5. The total line impedance for interconnected units cannot be such that it creates a voltage drop > 3.2 VDC.
6. Ground fault supervision is provided via the general trouble relay for domestic and via the dedicated ground fault relay in the
Canadian models. Enable ground fault detection on FL-PS1 and disable detection on FL-PS2-4 with negative (-) battery terminals
tied together. FACP ground fault supervision will be independent of cascaded PSE1-4. (FACP negative battery terminal is not tied
to PSE1).
The following notes apply to Figure 2.12.
1. Set FL-PS1 to Master Mode, and the desired strobe/horn type. Set remaining FL-PS units to Slave (sync follower) mode.
2. The debounce/dejitter setting must be set to 1 msec on FL-PS2 – FL-PS4 units. See Table 3.3 on page 23.
3. Strobe/Horn devices connected to the FL-PS units are not guaranteed to be in sync with FACP devices when using this
configuration
4. Any output used for remote sync applications cannot have notification appliances installed on the same circuit.
5. Notification appliances cannot be installed on the interconnecting control circuits.
6. The total line impedance for interconnected units cannot be such that it creates a voltage drop > 3.2 VDC.
7. Ground fault supervision is provided via the general trouble relay for domestic and via the dedicated ground fault relay in the
Canadian models. Enable ground fault detection on FL-PS1 and disable detection on FL-PS2-4 with negative (-) battery terminals
tied together. FACP ground fault supervision will be independent of cascaded PSE1-4. (FACP negative battery terminal is not tied
to PSE1).
NOTE: Any mode of operation that requires an additional control signal (i.e. a trigger signal), such as Selective Silence or Sync Mode, will
affect which Inputs may be available on PSE1 for use with cascading. (Triggers signals are usually assigned to Input 2.) Refer to those
sections of the manual for specifics.
