Module Specifications
Architectural/Engineering Specifications
Synchronization Circuit Module shall be a System Sensor Sync•Circuit Model _________ listed to UL464 and shall be approved for fire protective service. The
module shall synchronize SpectrAlert® strobes at 1 Hz and horns at temporal 3. Also, the module shall be capable of silencing the horns on horn/strobe models,
while operating the strobes, over a single pair of wires. The module shall be capable of mounting to a 411⁄16˝× 411⁄16˝× 21⁄8˝ back box and shall control two Style Y
(class B) or one Style Z (class A) circuit. The module shall be capable of multiple zone synchronization by connecting multiple modules together via a slave-in/
slave-out arrangement and re-synchronizing each other along the chain. Note: The module shall not operate on a coded power supply.
