[. . . ] Silence Input This input is used to silence the local sounder. The sounder will restart in response to any new fault or alarm. System Fault Reset Input This input is required to take the LSI-16 out of System Fault condition. Note: the LSI-16 will always power up in a system fault state (see connection diagram). 8 LSI-16 rear paneL System Test A system test can be initiated by simultaneously connecting monitored outputs 1 and 2 to ground (see connection diagram). A system test runs a diagnostic test, part of which illuminates each LED in turn and momentarily activates the sounder.

This output provides indication of when a message is playing or when a message has been muted. Constant active output - indicates a message is playing in response to an alarm input. Cyclic output (1. 25Hz) - indicates the message has been muted. General Fault, PSU Fault, Protection Fault and Path Fault These outputs will be activated by the same alarm conditions as identically named LEDs on the front panel (described above). Note however that these outputs will be activated by the faults listed above irrespective of whether a System Fault has been activated. The Voice Alarm Active, General Fault, PSU Fault, Protection Fault and Path Fault outputs are monitored for open-circuit or short-circuit to ground or power supply and for over-voltage on the output pin (>35V DC). If incorrect conditions are detected a Fault is signaled. Output monitoring facilitates compliance with voice evacuation standards. For each of these outputs, a load must be connected between each output and the positive voltage source. If any output on terminals 1 through 8 is unused, the output must be connected through an external resistor to the positive side of the voltage source (either 10V Out or user-supplied external source). To ensure correct functionality, the value of each resistor should be 22k. An internally derived 10V source is provided at the 10V Out terminal; however, the total current available from this pin is limited to 100mA. This voltage source may be used for external devices provided the total load is less than 100mA. For higher-current devices, a user-supplied external voltage source of up to 35V may be used, with the negative side connected to the pin. [. . . ] Mounting the unit using four screws with washers will prevent marring of the front panel. Please install the unit away from heat sources, such as vents and radiators, and in rooms with adequate ventilation. Ensure that air can circulate freely behind, beside, and above the unit. Do not exceed the maximum ambient operating temperature of 32-113 degrees F (045°C). [. . . ]
