Controlling Four NACs With One Input and Selective Silence Applications The control module is shown to demonstrate the use of a remotely mounted device associated with an addressable fire alarm control panel. The module could be replaced with any circuit capable of polarity reversal, such as an FACP NAC. Note: All NACs are supervised and power-limited (Class 2) ELR not required for Style Z (Class A) NAC Horn/Strobes Alarm Polarity Shown Use listed ELR (4.7K) to terminate Style Y (Class B) NAC Horn/Strobes Alarm Polarity Shown Style Z (Class A) Style Y (Class B) 24fsapp7tpH.wmf Internal Trouble Contact HPF-24S ZNAC-4 Option Module Output/NAC 4 Output/NAC 3 Output/NAC 2 Output/NAC 1 HPF24S has been set for SW1 Switch Settings 1 & 2 = sync (any setting but OFF/OFF) 3 = OFF (master) 4 = OFF (no AC Fail reporting delay) 5 6 = = ON ON (selective silence) 7 = OFF (charger enabled) 8 = OFF (circuit 4 NAC function) T11 T10 T9 T1 T2 SLC T8 T3 T7 T4 T6 T5 Selective Silence and Relay End-of-Line Resistor supplied with Control Module Module has been programmed at FACP as a silenceable point so it can perform selective silence when its Normally Open contact (8 & 10) closes in T11 alarm, then opens when silence T10 T9 T1 T2 SLC is invoked at the FACP. T8 T3 T7 T4 T6 T5 Note: the Relay Module can be mounted on the power supply inside the cabinet. This allows Control Module* EOL Power Relay Module* power wiring to remain inside the cabinet. *If the SLC device does not match the one in this figure, Supervision Relay refer to the SLC manual wiring conversion charts for legacy and newer versions of the modules. EOLR-1 (energized) Figure 5.1 Controlling Four Outputs With One Input The following notes apply to Figure 5.1 on page 29. 1. When the HPF-24S 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).
