Simplex 5120-9141 25 Volt Line Conversion Board

COMMUNICATIONS Options and Accessories 25 Volt Line Conversion Board Requires One Slot in Standard 5110 5120 Directly Compatible with Existing 25 Volt Twelve 25 Volt Line Outputs per Board Directly Compatible with 5130 9140 Boards in 5110 5120 Systems Provides Two Wire Call In Capabilities Precision Wound High Efficiency Rack 5120 9141 25 Volt Conversion board provides the Series Communications Systems with the ability drive speakers with 25 volt transformers This allows the of existing speakers in retrofit applications while still the advanced features of the 5100 systems new board does not change the 5100 system unique 1 watt chip amplifier design The 5100 system architecture which provides unsurpassed redundancy an amplifier for each speaker is uncompromised This allows paging operation even when a speaker circuit shorted Other intercom systems which incorporate one paging amplifier can lose paging capabilities if a single circuit is shorted 5120 9141 also provides the ability for Wire This allows a 25 volt line speaker and call switch to over a single twisted shielded pair of wire The 5120 can operate on two individually twisted pairs as well the room speaker connected to one pair and its call switch connected to the other Since both these wiring schemes were commonly used most retrofit can be easily supported Conversion board offers both standard telephone punchblocks and screw terminal blocks 5120 9923 for existing wire in retrofit applications The screw blocks should be used whenever stranded wire or solid larger than 20 AWG is being terminated Conversion Board accommodates 12 speaker and requires one slot position in the 5110 5120 card The 5120 9141 does not require power nor occupy an in the 5100 system of Outputs connections
