Sync*CircuitTM Module
The Sync*Circuit module synchronizes SpectrAlert(R) Advance strobes at 1 Hz and horns and chimes at temporal 3 over a single pair of wires. Patented module technology also allows the silencing of horns or chimes on horn/strobe and chime/strobe models over a pair of wires.
Features
* Two-wire operation from module to the devices * Silences horns and chimes over a two-wire loop * Synchronizes strobes at 1 Hz * Synchronizes horns and chimes to temporal 3 pattern * Patented technology * Allows slave module operation
The MDL Module is designed to work with the SpectrAlert and SpectrAlert Advance series of notification appliances to provide a means of synchronizing the temporal-coded horns and chimes, synchronizing the one-second flash timing of the strobe, and silencing the horns and chimes of the horn/strobe and chime/ strobes combination over a two-wire circuit while leaving the strobes active. Application Flexibility. The Sync*Circuit module is designed to power and synchronize either two 3-amp circuits wired in Class B, or one 3-amp circuit powered as Class A. Should more than two zones require synchronization, additional modules can be added by interconnecting the "slave" input and output terminals between modules.

Sync*CircuitTM 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(R) 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 41116x 41116x 218 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 514 L x 514 W Mounting 41116 x 41116 x 218 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 HORNS U.S. Patent Nos. 5,598,139 SILENCED OVER TWO WIRE CIRCUIT MASTER MODULE HORN CONTROL CONNECTS 5,850,178 TO INTERRUPTABLE POWER SOURCE
