and radiate radio frequency energy If this is not installed in accordance with this manual it may cause to radio communications This equipment has been tested found to comply within the limits for Class A computing devices to Subpart B of Part 15 of the FCC Rules These rules are to provide reasonable protection against such interference this equipment is operated in a commercial environment of this equipment is likely to cause interference in which the user at his own expense is required to take whatever measures be required to correct the interference Supplementary Systems Manual history

Transmitter AFIR AFIT fiber optics receiver transmitter pair extends a low audio circuit via supervised fiber optic cables The transmitter converts electrical audio information into light for transmission on fiber optic link The receive card re converts the light back into an signal for the audio circuit Type ST connectors are furnished the modules with type SMA connectors available on special order SYSTEMS TECHNOLOGY RECEIVER 130142 AMP DC SYSTEMS TECHNOLOGY TRANSMITTER 130141 AMP DC Supplementary Systems Manual optic links are suitable for application in areas of high electrical explosive atmospheres high security applications or where faults are a problem Optic Cable Optic Cable Optic Budget Impedance signal 62.5 125 or 100 140 Multimode ST SMA on special order Fiber 0 13 dB

should be given to the routing of fiber optic within enclosures to avoid mechanical interference due to tight in the fiber optic cable There should be no stress on the fiber cable or the module Refer to fiber optic cable manufacturers for minimum bend radius allowable tension load and stress Optic Connections optic connections are made to the AFIR or AFIT through ST connectors Do not remove the protective caps on the ends or the fiber optic ports on the cards until ready to make the This reduces contamination by dust or foreign material Connections Shield Not Used Low Level Audio Input AFIT

adjustment Rotate the input attenuator located between the electrical fully clockwise 10 15 turns Supplementary Systems Manual Connect an oscilloscope between the test jack located next to the port and the case of the transmitter Apply the 1 kHz audio signal and adjust the attenuator until a 0.8 V peak to peak signal is obtained Clipping will occur above this level Connect the fiber optic cable to the receiver and a 600 resistor to output terminals Connect an oscilloscope across the 600 resistor Apply a 1 kHz 1 Volt signal to the transmitter Adjust the output control located between the electrical connectors until a 1 signal is obtained Supplementary Systems Manual Busy Signal Module Busy Signal Module BSM is a modular system component for with traditional zone modules such as the ZB8 8 and RZB12 6 BSM provides a busy signal for firefighter telephone system and warden stations that are operational but not actively with the fire command center The BSM may be to existing hardwired telephone circuits IN B B A A Signal Module of Operation BSM is used with up to two traditional zone circuits and RZB12 6 configured as supervised output control circuits When the output circuit is shorted by activation of the warden station inserting a handset jack the BSM injects the busy signal tone onto supervised telephone circuit passing the supervis
