<br /> <br />G-260 <br /> <br />MDL & MDLW <br />Sync Modules <br />for use with the SpectrAlert™ Series <br /> <br />Section: AudioNisual Devices <br /> <br />GENERAL <br /> <br />System Sensor's MDL Sync Module is designed to work with <br />the SpectrAlert series of horns, strobes, and horn/strobes to <br />provide a means of: synchronizing the temporal-coded horns, <br />synchronizing the one-second flash timing of the strobe, and <br />silencing the horns of the horn/strobe combination over a two- <br />wire circuit while leaving the strobes active. <br /> <br />MODULE CONFIGURATION <br /> <br />Each MOL module has the capability of connecting two Style Y <br />(Class B) circuits or one Style Z (Class A) circuit. <br /> <br />The NAC output(s) from the panel are connected to the zone <br />inputs of the MOL module and the zone output(s) from the MOL <br />module are connected to the notification loop(s). Supervision <br />is accomplished in the module by a direct connection between <br />the zone input and the zone output of each of the two zone <br />circuits connected to the normal end-of-line device. The FACP <br />"sees" the EOL device through the MOL module. When either <br />or both outputs (zones 1 & 2) from the module are wired to the <br />SpectrAlert products, the horns and strobes in both zones will <br />be synchronized. <br /> <br />The MOL module can be configured so that more than two zones <br />can be synchronized by the interconnection of the slave input <br />and output (see Application Examples). <br /> <br />SPECIAL CONSIDERATIONS <br /> <br />A latching Form-C contact is provided in case the synchroniz- <br />ing signal to the notification devices is interrupted. The output <br />can be wired so that a trouble signal will be annunciated at the <br />panel. If the synchronization pulse fails in the MDL module, the <br />strobes will shut off. <br /> <br />NOTE: The MDL Module is factory-set with the trouble contacts in the <br />open state. These contacts may close during shipping. ApproXimately <br />two seconds after power-up, these contacts will open. <br /> <br />SPECIFICATIONS <br /> <br />Voltage range: OC or full-wave-rectified; 11 to 30 volts. <br /> <br />NOTE: Supply voltage range at 12 volts - 11 to 17 VDC; <br />at 24 volts - 21 to 30 VDC. <br /> <br />Maximum load on loop: 3 amps. <br /> <br />Current: chart at right. <br /> <br />Operating temperature: OOC to 490C (320F to <br />120"F). <br /> <br />April 9, 1998 <br /> <br />@@ <br /> <br />MEA <br /> <br /><&> <br /> <br />OD4A7.AY <br /> <br />254-97-M <br /> <br />S5512 <br /> <br />CS548/CS549 <br /> <br /> <br />California <br />State Fire <br />Marshal <br />7300-1209:179 <br /> <br /> <br />The MDL Module <br /> <br /> Average Peak In-Rush <br />Voltage <br /> DC FWR DC FWR DC FWR <br />12 V 10mA 12 mA 30mA 31 mA 87 mA 122 mA <br />24V 11 mA 15 mA 35 mA 37 mA 198 mA 262 mA <br /> <br />SpectrAlert'M and Mini-Alert™ are trademarks of System Sensor, a <br />division of Pittway Corporation. <br /> <br />This document is not intended to be used for installation purposes.
