Mircom’s SIS-204 Speaker Isolator Module is designed for installations where disconnection of, or damage to an in-suite speaker will not interfere with the ability of speakers in other dwelling units, public corridors or suites to sound on an alarm. The SIS-204 works in conjunction with the QX-5000 Zoned Audio System and comes equipped with trouble LEDs. The LEDs are only operable when the isolator is used in a supervised connection.
The SIS-204 Speaker Isolator Module can be connected in a supervised or non-supervised configuration. In a supervised configuration, the SIS-204 provides two supervised outputs. Under this scenario, if the in-suite speaker has a open circuit, the fire or audio control panel will indicate a zone trouble and the isolator LED will fl ash to indicate which isolator has the fault. The trouble LEDs flash to indicate a positive or negative fault on the isolator. When the left amber trouble LED flashes, it indicates an open on the positive side and consequently, when the right amber LED fl ashes, it indicates an open on the negative side. In a nonsupervised configuration, the SIS-204 provides four non-supervised outputs. Under this scenario, if a short or open circuit occurs, the isolator disconnects the speaker from the circuit but it does not indicate a trouble on the fire or audio control panel. In this configuration, an open circuit in the suite does not indicate a trouble on the control panel.
