The operating temperature range is -10 to +50°C. As provided with guard nets inside to cover over the openings of microphone and speaker, the AN-8050DS can be installed free from care in public space. 2. WALL MOUNTING 2.1. Mounting to a 3-gang Switch Box (with cover) 3. INSTALLATION PRECAUTIONS M4 x 25 (accessory) Notes • The wall should be over 12 mm thick, and the opening in the wall for an electrical box should be under 115 mm (wide) by 162 mm (high). • When using for electronic door lock control, fix the AN-8050DS with tamper-proof screws such as "Torx" screws to prevent it from being easily removed. «Accessory screws The AN-8050DS comes with 2 types of screws; oval head combination screw M4 x 25 and oval head slotted screw UNC No.6x18. For the electrical box provided with unified threads, use the oval head slotted screws UNC No.6 x 18. 2.2. Mounting to the YS-13A Wall Mount Box Install the YS-13A on a wall and mount the station in the same way as 2.1. Seal the panel When installing the AN-8050DS outdoors or at locations where it gets wet with water, tightly seal the panel edges. Besides, provide a weep hole at the underside of the mounting box to permit water to drain off. AN-8050DS's front panel 4. WIRING 4.1. Connection to the Exchange Connect the Exchange to the station's LINE terminals via the E-7000TB Terminal Board as Illustrated. AN-8000EX Exchange | 16 lines | 4.2. Connection to an External Relay AN-8000EX Exchange Diode -^- Relay External power supply +24 V DC GND UNE H c Open collector output: 30 V DC, 50 mA AN-8050DS (Rear panel) 4.3. Type of Cable Step 2. Loosen the terminal screws and insert the cables. The types of cables are to be determined according to the following conditions. • Twisted pair wires (such as those used for electronic push-button telephone) are to be used for wiring between the Exchange and the stations in principle. • The number of cables pairs laid should be determined considering the possibility of future expansion of the system. ® Outdoor wires should be used where wiring passes through inaccessible areas such as ceilings or under floors where the maintenance is not performed. Indoor wires may also be used, however, in case where there is no risk of deterioration due to exposure to heat, etc. Note Specifications related to each junction are as follows. Mini-clamp connector (AN-8000EX line terminal) Conductor diameter: 00.4 - 0.65 mm (AWG22 - 26), solid wire Outside diameter: 01.05 mm or below Clip terminal (E-7000TB) Conductor diameter: 0O.4 - 0.8 mm (AWG20 - 26), solid wire Outside diameter: 01.5 mm or below Terminal station (LINE, H, C terminals) Conductor diameter: 00.4 - 1.3 mm (AWG16 - 26), solid wire, stranded wire 4.4. Relations Between Core Diameter of Cable and Maximum Cable Length Referring to the following chart as guidelines, design the distance between the Exchange and stations so that loop resistance becomes 170 Q or less. Step 3. Tighten the terminal screws securely. Notes •Tug lightly on the cable to be sure that it does not pull free. If the cable pulls free, loosen the terminal screw again and reconnect from Step 2. •To avoid stripping the screws, use the screwdriver appropriate to the screws tightened into the terminal plug. Tighten Terminal screw Cable 4.6. Mini-clamp Connector Connection Connect the mini-clamp connector supplied with the AN-8000EX to a cable using a commercially available tool (pliers). Step 1. Cut off two-cable ends in equal length, and insert them securely to a cover section (transparent side) of the mini-clamp connector. Note ?over Insert the cable without ^ran.parem siae) stripping the cable jacket. Cable Conductor diameter (mm) Loop resistance (D/ km) Maximum cable length between the Exchange and station.

Strip a cable jacket of approx 7 mm to expose inner cable. For cables, refer to The Type of Cables. 7 mm -^Ss. - r I % !) Note Do not solder plate on exposed inner cables when using a stranded wire. Step 2. With a pair of pliers, lightly pinch the mini-clamp cover and, after ensuring that the cable Is securely inserted, firmly squeeze on the cover. Note Squeeze on the minl-clamp cover until It is correctly locked. Step 3. Insert the wired connector (plug) into the exchange's connector (socket) until it locks into place. Si Al PHONE...
