i HAZARD electrical power when making any internal servicing be performed by qualified Simplex Representa MICROPHONE AND ENCLOSURE MODULE DESCRIPTION Refer to Fig 1 2001 6030 Microphone and Enclosure Module contains a microphone a microphone enclosure and two oscillator control module and the dual pre amp monitor module The used to transmit voice messages over the 2001 Voice Communications System speakers daughter cards usually microphone contains a and allows any output signals preamplifiers via the mike interface which when pressed deactivates the voice coil cartridge 2 to transmit player music and all the primary and REFERENCE enclosure module circuitry WD No None shown on the following drawing and Enclosure And Enclosure Module 1 FUNCTION Refer to Fig 2 Condition microphone switch through the switch Sl contacts in the released position and any output signals the voice coil cartridge are COIL OUT WHEN MIKE SWITCH PRESSED STOP PLUG P2 DISCONNECTED BETWEEN PINS P2 2 AND WHEN MIKE SWITCH RELEASED OHMS RESISTANCE BETWEEN PINS AND P2 3 WHEN MIKE SWITCH PRESSED OHMS AUDIO SYSTEM COMMON And Enclosure Module Cards Not Included 2 Condition Microphone Operation operate the microphone when the system is in its normal condition perform the following Remove the microphone Set the OSC STOP switch to the up position the panel all oscillators and music Set either the ALL CIRCUITS switch or selected SPKR CKT switches the up position The ALL CIRCUITS switch activates all the system speakers The selected SPKR CKT switches activates specific system speakers Press the microphone switch to transmit voice messages over the selected system speakers Switch Sl opens and the output signals of the voice coil cartridge are fed to pins P2 2 and P2 3 The signals are then transmitted the mike interface transformer Switch S2 closes and OV is sent out pin P2 1 inhibits tape player music and all oscillators Reverse procedure when finished To operate the microphone when the system is in its alarm condition you may eliminate steps 2 and 3 REMOTE MICROPHONE AND ENCLOSURE MODULE DESCRIPTION Refer to Fig 3 2001 6037 Microphone speakers daughter cards the remote oscillator control module and
