The SP4Z-A/B shall enable a single supervised speaker audio output to drive up to two Class A supervised speaker audio outputs or four Class B supervised speaker audio outputs. Each Class A zone shall be capable of accepting up to 40 watts and operate on either 25 or 70.7V RMS of audio input. Each Class B zone shall be capable of accepting up to 40 watts of audio and operate on either 25 or 70.7V RMS of audio input.The SP4Z-A/B shall be capable of supporting live microphone paging, prerecorded emergency voice evacuation messages, supervised background music and general paging announcements. The SP4Z-A/B shall mount inside the enclosure of the SP40S,SP40/2,SPB-80/4,SPB-160 and SPB-320 and shall have power and trouble LED's with individual zone short and open LED indication. The SP4Z-A/B shall be capable of detecting wiring faults. The SP4Z-A/B shall be powered by 24VDC,which is to be supplied by the SP40S, SP40/2,SPB-80/4,SPB-160 or SPB-320. Standby and Alarm current at 24VDC shall be 15mA. Removable wiring terminals for quick connect/disconnect accepting 12-22 AWG shall be incorporated. All output circuitry shall be power limited. Space shall be provided to allow for naming of the zones. Addressable Paging Splitter and Telephone Zone Controller The Wheelock Addressable Paging Splitter(SP4-APS) and Telephone Zone Controller (SP4-TZC) shall be used to control and direct telephone paging and background music zones connected to the SAFEPATH4 Multi-Function Facility Communication System using an RS485 connection. The Addressable Paging Splitter (SP4-APS) shall be UL Standard 864, 9th edition and California State Fire Marshal (CSFM) approved, addressable and supervised 2-zone Class A or 4-zone Class B Speaker splitter. The SP4-APS shall be used with Wheelock's SP40S or SP40/2 panel and the Audio Booster(SPB-160,SPB-80/4,and SPB-320)panels.Each SP4-APS shall have a single audio input capable of 25 Vrms or 70.7 Vrms at a maximum of 80 Watts.The input audio power shall be distributed to the zone connections with the total not exceeding the input and no zone exceeding 40 Watts. When audio boosters are connected, each audio booster module shall consume 1.2 Watts from the total input power of the SP4-APS. The splitter shall be mounted inside the SP40S, SP40/2 or Audio Booster that it is associated with, and it shall operate on 24VDC supplied by the supported module.The SP4-APS shall contain 16 LED indicators used to monitor and troubleshoot the module. The Telephone Zone Controller Module(SP4-TZC)shall be used to address the output zones on the SP4-APS.The SP4-TZC shall be capable of supporting 17 SP4-APS speaker splitter modules and shall be capable of addressing all zones at once("All Call"),a maximum of 68 separate zones, 17 fixed zone groups and 9 programmed logical zone groups.This shall be accomplished using two digit DTMF tones from a page port, an unused CO port, or a stand alone telephone with a loop start circuit.Also, the SP4- TZC shall be able to select zones for background music. The SP4-TZC has the following inputs: Power, USB port, Background Music(BGM), Page Audio in. The outputs are:Audio out and RS485 Digital Control.The basic operating parameters of the SP4- APS shall be pre-programmed. Customized programming shall be accomplished using a USB cable and programming computer software.The SP4-TZC shall be powered using a 24VDC filtered and regulated power supply such as the Wheelock RPS-2406. The Controller Module assembly is mounted in a metal enclosure measuring 13"L x 7 5/8"W x 2"D. Supervised Volume Control The Wheelock SP-SVC shall be UL Standard 864,9th edition approved,supervised volume control for use with the SAPEPATH°4 Facility Communications System. The SP-SVC shall provide for manual volume setting for telephone paging and background music for a specific speaker or speaker zone. The selected adjustment will not affect the volume setting of emergency prerecorded messages or live microphone usage. The SP-SVC shall be capable of handling up to 35 watts of audio power @ 70.7 volts or 4 watts audio power @ 25 volts and shall operate on either 70.7 or 25 volt input from an SP40S or Audio Booster. The SP-SVC shall be capable of operating in Class B or Class A wiring configurations (for Class A, the SP4-APS is required). The SP-SVC shall receive operating power from an Audio Booster, SP40S or SP40/2. Volume adjustment settings shall be off, 1 — 10, in 3dB increments. The SP-SVC shall be supplied with a stainless steel mounting plate with a black knob and require a double gang, 3'/2"deep back box for mounting. Remote Microphone The Wheelock SPRM shall be UL Standard 864, 9th edition and California State Fire Marshal (CSFM) approved, Remote Microphone for use with the SAFEPATH14 Facility Communications System. The SPRM shall be a supervised hand held push to talk microphone and a key shall be required to enable remote microphone use. (Same key as SP40S or SP40/2) Removable wiring terminals for quick connect/disconnect accepting 12—22 AWG shall be incorporated. All output circuitry shall be power limited. Individual front panel LED's shall be provided for indication of System Normal,System Trouble and Alarm. Multiple on board diagnostic LED's shall be provided. When used with the SP40S or SP40/2, the priority level shall be number two. Remote microphone usage shall disengage background music and general paging. Voice frequency response shall be 275 Hz-6.5 kHz+/-2.4 dB. Power requirements shall be 24VDC and will be supplied by the SP40S or SP40/2. Input current for Standby shall be 26mA and for Alarm 38mA. Audio output level shall be 1.05V RMA. There shall be a 6-wire connection to the SP40S or SP40/2. The mounting plate shall be red and measure, 8 3/4"x 5 '/4", and shall fit into a 4 gang back box. 15
