Valcom Ambient Level Controller

PagePac 1 LEVEL CONTROLLER Ambient Level Controller ALC constantly monitors noise and adjusts the paging level to accommodate any changes in noise level It has a built in Sound Level SPL meter ALC has two inputs a loop start input Telco and a 600 Ohm line input The Telco input shall have over the line input The microphone can be placed to 5000 feet from the ALC with shielded wire The ALC five contact closure clock or remote control inputs The ALC has four double throw relay outputs that on the 6 dB and 0 dB levels ALC adjusts page system level in 6 dB steps The Telco input is loop start and has priority over the input The line input has a dry contact closure which will provide an isolated dry contact closure at connections of the line output Power consumption Frequency Response Signal to noise dB ref Maximum output level Output relay activaltion points Output relay contact rating Number of relay output contacts Input level controls internal Control requirements Input types Output types Contact closure on output Contact closure controlled input Front panel controls Front panel indicators Maximum MIC line length Watts Hz to 15 KHz 2dB than 60dB 12dB with jumper installed and 6dB gain reduction Amp contact closure Telco loop start only 600 Ohm manual or automatic automatic input active feet Manuals Online Manuals Online Allows automatic manual or remote control of paging system audio levels SPL meter with over 50 dB range built in Microphone can be placed up to 5000 feet from unit Balanced 600 Ohm inputs and outputs Loop Start Telco input with priority over line input Clock contact closure or remote control input connections Relay outputs for emergency override or indicators Dry contact closure on line input activates isolated dry contact closure on line output Internal microprocessor senses ambient noise via a MIC input and adjusts the paging level Rack or wall mount single rack space 24VAC UL listed power supply Part 15 FCC approved 17 x 1.75 x 8.75 19 with rack ears x 4.45cm x 22.23cm 8 lbs 3.63 kg 32 to 104 F 0 to 40 C 0 to 85 non condensing ASSISTANCE calling have a VOM and a telephone test set available and call from the job site 800 782 5266 and ask for PagePac Technical Support or call 540 427 6000 for Valcom 24 hour Support or visit our websites at http www pagepac com and www valcom com repairs be necessary attach a tag to the unit clearly stating company name address phone contact person and the nature of the problem Send the unit to Inc Repair Dept Hollins Road VA 24019 5056 Manuals Online Manuals Online PORT Use only the Log Current Microphone standard microphone will be if connected to the FM 15 OHM PORT LINE These terminals are redundant input connections Useful a modular RJ 11 plug and is not suitable Modular or Input V olts AC In Start In G Only Only C Outputs NO C Inputs or Remote Control C C C C C C Out C1 C G B Y Out to Page Input These terminals are redundant input connections Useful a modular RJ 11 plug and is not suitable V AC 50 60 Hz dBm OUT AGE IN R Y R G V AC 50 60 Hz dBm OUT IN R Y R G A to Dry Loop 600 Ohm 1 Connection to Conventional Paging System Manuals Online Manuals Online HOST PLUS Zone to Contact Output Input V olts AC In Start Input In Out C1 C G B Y 0dbu Modular or Only Only C NO NO NO C C C Outputs Inputs or Remote Control C C C C C These terminals are redundant input connections Useful a modular RJ 11 plug cable is not available V AC 50 60 Hz These terminals are redundant page input connections when a modular RJ 11 plug and cable is not available A dBm OUT IN Y R G Input These terminals are redundant MIC input Useful when a modular RJ 11 plug cable is not available Input V olts AC In Start In G Out C1 C G B Y Only Only C NO NO NO C C Outputs Inputs or Remote Control C C C C C Out to Input These terminals are redundant page input connections when a modular RJ 11 plug and cable is not available V AC 50 60 Hz dBm OUT IN Y R G A 2 Multiple ALCs used with a Single Controller and Multiple Amplifiers Manuals Online Manuals Online Use only the Log Current Microphone standard microphone will be if connected to the FM 15 Dry Loop Start only not apply Voltage or Dial Tone Input V olts AC In Start In G Out C1 C G B Y Only Only Outputs
