Notification Appliance Wiring Installation
Class A Output Notification Circuits
The configuration shown in Figure 3.7 shows two, 3-amp devices wired as Class A circuits. When you are using the outputs as Class A cir-
cuits, loop the wiring back to the corresponding circuit pair. For Class A wiring, no external EOL is necessary since it is built into the 5496
board.
3.7.2 Class B Supervised Wiring
Figure 3.8 shows how to wire for Class B output supervision. Use in/out wiring methods for proper supervision. Refer to the Silent Knight
Device Compatibility Document for notification appliances that must be used with the 5496.
Class B Output Notification Circuits
Figure 3.8 shows four, 1.5 amp devices wired as Class B circuits.
Place a 4.7k ohm EOL resistor (provided) at the end of each circuit to enable supervision when using all outputs as Class B notification
appliance circuits. The 4.7k EOLs must be wired to the terminals whether or not you are using all output terminals.
3.7.3 Releasing Operations
Approved releasing solenoids are listed in the Silent Knight Device Compatibility Document. Only Class B wiring can be used for releasing
operations. Do not mix cross alarming zones with smoke verification zones. There must be at least two automatic detection devices in each
protected space. Spacing must be reduced to 0.7 times the linear spacing in accordance with NFPA 72.
An MRD-1 Manual Release Disconnect Switch can be used to disconnect the releasing circuits for testing and maintenance. Do not rely on
disable/enable software settings to lock out releasing devices. Releasing devices must be physically disconnected per UL 864 10th Edition.
Refer to the MRD-1 Installation Document #LS10231-000GE-E for more information.
