<br />Controlling Sounder On/Off Over Two Wires Using Module Horn Control <br /> <br />Connect the current source to the horn control input. If a zone output is used for the source, you must use an EOl on <br />the horn control input terminal. <br />. When multiple modules are used, the horn control circuits can be wired in parallel. If wired in parallel and a zone <br />output is used from panel, use an EOl on the last module for supervision. <br /> <br />ZONE 1 INPUT This input powers the MOL Module. This input must have voltage present from the <br />FACP before anything will work. This also supplies voltage to Zone 1 output. <br />ZONE 2 INPUT This input only supplies voltage to Zone 2 output. NOTE: If Zone 1 input is not <br />pov.ered, the notification devices attached to the Zone 2 output 'Aill not be allov.ed. <br />HORN CONTROL This input enables the horns on the SpectrAlert notification appliances. Voltage <br />present means horns are enabled. No voltage present means horns are disabled. <br />SLAVE IN Connects to Master MOL Module slave out. <br />SLAVE OUT Connects to Slave MOL slave in. <br /> <br />Horns Silenced Over Two-Wire Circuit <br />1) Any mix of SpectrAlert horns/strobes or strobe-only devices is acceptable. <br />2) Horn Control connects to interruptible power source. <br /> <br />i <br />P}~ONE2 TROUBLE{~ I <br />> i 2} SLAVE SLAVE{~ <br />I 8 IN OUT ~-1 <br />~ I <br />MODU~ TEMP.
