Split Alarm and Selective Silence Applications 5.3.2 Split Alarm Mode The Split Alarm mode shows the versatility of the HPFF. A combination of coded signals can be generated by or passed-through to the NAC output circuit pairs of 1&2 and 3&4. In this application, the power supply has been the configured for Split Alarm mode. Control Input #1 (TB3, Terminals 3 & 4) is connected to an addressable control module which will control power supply output circuits 1 & 2. Control Input #2 (TB3, Terminals 7 & 8) is connected to an addressable relay module which controls output circuits 3 & 4. If the programming DIP switches are set as shown below the power supply is set as a Sync Generator with two synchronized (System Sensor protocol) and two non-synchronized outputs. Control module #1 will cause the synchronized power supply output circuits 1 & 2 to turn on. Control module #2 will activate a Temporal Signal on output circuits 3 & 4. SW8 ON SW7 N/A SW6 OFF SW5 ON SW4 OFF SW3 ON SW2 ON SW1 OFF NAC outputs circuits 1 & 2 will have sync for System Sensor device. NAC outputs circuits 3 & 4 will have a Temporal signal. Two independent inputs are required for Split Alarm. 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 ULListed panel. Alternately, two outputs of a six-output addressable module can also be used and mounted on the Control board shown in Figure 5.4. Install jumpers supplied with module hpff8-spl-6up.wmf Supervision Relay Alarm Polarity Shown Figure 5.4 Wiring for Split Alarm Mode Notes for Figure 5.4: 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. Section 4.1, "Supervised Functions and Field Wiring". 2. Do not loop wires under screw terminals. Break wires to maintain proper supervision. 3. The value of the ELRs (End-of-Line Resistors) across TB3 terminals depends on the control module used. 4. For a list of compatible devices, refer to Appendix A, "Device Compatibility". 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. HPFF12 NAC Expander - P/N 53576:B 11/24/2010 45
