Notifi cation/Release Circuits
The output circuits of the VFR-400 are Non-coded. This allows the use of visual and audible appliances on the same circuit. If
temporal notifi cation appliances are required for evacuation, selectable tone appliances such as the AMSECO H24W horn or
SH24W Series strobe/horns or a temporal module such as AMSECO TMP1-3A or equivalents should be used.
The notifi cation outputs do not provide synchronization. If synchronization is required, use AMSECO SMD10-3A
synchronization module or equivalent, as identifi ed on page 55. The notifi cation appliances shall be compatible with the sync
module selected. The current requirements of the appliances, wire gauge, and length of wire run determine the maximum
number of appliances that can be connected to one NAC and/or sync module. The maximum cannot exceed 1 amp or whatever
the sync module selected can support, whichever is lower. The sync module shall be installed as per manufacturers instructions.
Equivalent sync modules are shown on page 55.
