Notes:

Shielded cable inogona kuderedza kureba kwetambo inowanikwa. Shielded cable inofanira kuiswa paControl inoperera chete.

Kana mamwe marudzi etambo akashandiswa, madaro ekushanda uye kushanda kunogona kuderedzwa zvichienderana nemhando yetambo.
Kurudziro yekushanda kwakaringana inosvika makumi maviri T20 Keypad Readers inogona kubatana kune imwe Controller 30.

Distance pakati pevaverengi

Chinhambwe chinoparadzanisa chero vaverengi vaviri vari pedyo hachifanirwe kunge chiri pasi pe200 mm (8 mukati) kumativi ese. Paunenge uchiisa chiverengero chepedyo pamadziro emukati, tarisa kuti chero muverengi akaiswa kune rumwe rutivi rwemadziro haasi pasi pe200 mm (8 mukati) kure.

Installation

Iyo Gallagher T30 Keypad Reader inogona kuiswa pa:

bhokisi rakatwasuka, rectangular 50 mm x 75 mm (2 mu x 3 mukati)

BS 4662 British Standard square flush bhokisi
chero nzvimbo yakasimba yakati sandara

Iyo yakakurudzirwa kureba yekukwira yemuverengi ndeye 1.1 m (3.6 ft) kubva padanho repasi kusvika pakati pemuverengi. Nekudaro, izvi zvinogona kusiyana mune dzimwe nyika uye iwe unofanirwa kutarisa mirau yemuno yekusiyana kune iyi urefu.

Notes

Kutariswa kunofanirwa kupihwa kune yekumisikidza nharaunda kana uchishandisa Bluetooth® inogonesa vaverengi, sezvo huwandu hwekuverenga hunogona kudzikiswa.

Kuiswa panzvimbo dzesimbi, kunyanya dzine nzvimbo yakakura inoderedza kuverenga. Kuwanda kwekuderedzwa kwacho kuchaenderana nerudzi rwesimbi. A spacer (C300318 kana C300319) inogona kushandiswa kubatsira kurerutsa nyaya iyi.
Ndiro yedhirezi nhema (C300326) inogona kushandiswa kuvhara vaverengi vakamboiswa kuve nechokwadi kupera kwakachena kwemasaiti anobata kusimudzira.

Paunenge uchikwira pabhokisi rinoputika, zvikoni zvekona zvinofanira kushandiswa pamwe chete nemagetsi ebhokisi. Pasina makona screws kumusoro kwechigadzirwa kunokanganisa kuparadzaniswa kubva pamadziro.

Ita shuwa kuti tambo yekuvaka yapera kuburikidza nebhokisi rekutsvaira.
Kana usiri kukwira kubhokisi rinoputika, shandisa bezel yekuverenga segwara, kuchera maburi ese mashanu. Dhobora 13 mm (1/2 inch) dhayamita yepakati buri (iri ndiro buri repakati iro tambo yekuvakisa inobuda panzvimbo inokwirisa) uye makona mana ekugadzirisa maburi. Ita shuwa kuti buri repakati rinobvumira tambo kuti imhanye zvakasununguka kuburikidza neinokwirisa pamusoro, kuitira kuti muverengi facia anogona kunyura mubezel.
Ongorora: Iko hakuna nzvimbo yekuti tambo yekuvaka isvinirwe mubezel yemuverengi. Tambo yekuvaka inofanira kuramba iri mukati mebhokisi rekutsvaira kana madziro emadziro.

Mhanya tambo yekuvaka kuburikidza nemuverengi bezel.
Chengetedza bezel kubhokisi rekutsvaira uchishandisa screws mbiri dzakapihwa.
Paunenge uchichengetedza bezel kune yakamira, rectangular flush bhokisi, shandisa iyo 6-32 UNC screws yakapihwa. Kana uchichengetedza bezel kuBS 4662 British Standard square flush box, shandisa M3.5 screws yakapihwa.
Dhobora maburi ekutyaira emakona mana ekugadzirisa maburi uye tamper tab. Chengetedza bezel kunzvimbo inokwirisa uchishandisa makona mana ekugadzirisa screws akapihwa. Chengetedza tamper tab (iri mubezel) kune inokwirisa pamusoro uchishandisa yakasara yekuisa screw yakapihwa. Izvo zvakakosha kuti makona mana ekugadzirisa screws anoshandiswa kuve nechokwadi chekuti muverengi anotsvedza uye akasimba pakatarisana nenzvimbo inokwira.
Cherechedza: Zvinokurudzirwa kuti ushandise screws dzakapihwa. Kana imwe sikuruu ikashandiswa, musoro haufanire kunge wakakura kana kudzika kupfuura iyo screw yakapihwa.
Batanidza muswe wemuverengi unobva pamusangano we facia kuenda kutambo yekuvaka. Batanidza waya dzeHBUS mudziyo kuti uenderane.
Chishandiso cheHBUS chinobatana neGallagher Controller 6000, Gallagher 4H/8H Module, Gallagher HBUS Door Module, kana Gallagher HBUS 8 Port Hub.
Kuti umise mudziyo weHBUS, batanidza waya yeOrange (HBUS Termination) kuwaya yeGreen (HBUS A).
Isa iyo facia musangano mubezel nekuchekerera muromo mudiki, kumusoro kwebezel uye kubata kumusoro, dzvanya pasi peiyo facia musangano pasi mubezel.
Cherechedza: Ita shuwa kuti hapana kudzvanywa pawaya yakatarwa painobuda muverengi. Ita shuwa kuti waya seti haibudi muverengi nekona yakapinza, sezvo izvi zvinogona kukanganisa kutendeseka kwewaya seti yemvura chisimbiso.
Isa iyo M3 Torx Post Security screw (uchishandisa T10 Torx Post Security screwdriver) kuburikidza negomba riri pazasi pebezel kuchengetedza kusangana kwechiso.
Cherechedza: Iyo Torx Post Security screw inoda kungosimbiswa zvishoma.
Kubviswa kwemusangano we facia ndiko kudzoreredzwa kuri nyore kwematanho aya.
Gadzirisa muverengi muCommand Center. Tarisa kune musoro wenyaya "Kugadzira HBUS Keypad Reader" muMurairo Center Configuration Client Online Rubatsiro.
