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. Physical Specifications Dimensions 51⁄4˝ L × 51⁄4˝ W Mounting 411⁄16˝ × 411⁄16˝ × 21⁄8˝ back box Indoor Operating Temperature 32° to 120° F (0° to 49° C) Electrical/Operating Specifications Operating Voltage 12 or 24 VDC and FWR unfiltered Operating Voltage Range (12 V) 9 to 17.5 VDC Operating Voltage Range (24 V) 17 to 33 VDC Maximum Load on Loop 3 Amps/zone U.S. Patent Nos. 5,598,139 5,850,178 HORNS SILENCED OVER TWO WIRE CIRCUIT MASTER MODULE HORN CONTROL CONNECTS TO INTERRUPTABLE POWER SOURCE SLAVE MODULE NAC1 TO NEXT SPECTRALERT DEVICE OR EOL All SpectrAlert horns, horn/strobes, and strobes will operate in sync.
