2.2 Stations 2.2.1 Features The stations used in the Toa Intercom EX-16 have the following features: 1. Each station is provided with a male 4-pin plug (YC-102) for easy con- nection to cables. 2. Wiring from the exchange to each station is an independent 4-wire system. The fact that only 4 wires are necessary makes installation easier, and with a 4-pin jack (YC-101 or YC-103) at the end of each cable, connection can be made quickly with only a screwdriver. There are three types of stations avai

3. Installation of the EX-16 System 3.1 Precautions for Installation 3.1.1 Exchange Pay particular attention to the following points: * The layout should allow easy servicing and inspection. * The exchange is compact and lightweight; however, it is important to ascertain the strength of the wall on which it will be placed. * The exchange should be grounded. When it is used in combination with other systems (for example, with a PA system) the exchange should be connected to the other components

3.1.2 Stations Particular attention should be given to the following points during installation. * A desk-type, wall-mounting-type or desk/wall-type should be chosen according to the user's need. * If the all-call paging or talk-back function is adopted, precautions should be taken to ensure against feedback due to interference between the station (microphone) and the paging or talk-back speaker; that is, they should be installed facing different directions or separated as far as possible from e

3.2 Cable Installation Wire type, number of wire pairs and number of individual wires are to be determined for individual sections of the wiring system according to the guidelines set down below. * 4-wire twisted pair cables are to be used for wiring between indoor terminal boards, intermediate terminal boards, main terminal boards, etc. * Outdoor wires should be used where wiring passes through inaccessible areas such as in ceilings or under floors. Indoor wires may also be used, however, in ca

3.4 Wiring General Information * Wiring should be done independent of public telephone lines. * The wiring conduit is often installed underground or embedded in building structures such as walls and floors, so care should be taken to draw up a wiring plan that has ample reserve for future extension of the system and that can be adapted to future remodelling or expansion of the building it is housed in. Wiring systems must be planned with ample wires, a conduit and with provisions for additions t

3.5 Piping * Where wiring is to be passed through a wall or the like, it should be protected by a hard PVC or metal tube. * If the number of connecting wires between an indoor terminal board and a station is small and the station's site is fixed so that it will not be moved frequently, install a box at that site and pull wiring through a metal or hard PVC tube as required by job or ordinance. * Use a floor duct if the number of connecting wires is large and the stations are likely to be moved fr
