Run the external antenna. If you have an external antenna, it extends the range of your wireless remote or keypad by receiving the signal from outside the car and transmitting it to the car alarm module. Most external antennas are glass mount antennas. This means that you will mount a receiver on the outside of your glass and a repeater on the inside of the same glass. The signal will be transmitted through the glass with no need to drill holes and the repeater wires directly to the antenna wire of your alarm module.

Tashqi antennani ishga tushiring. Agar sizda tashqi antenna bo'lsa, u simsiz masofadan boshqarish pulti yoki klaviatura diapazonini avtomobil tashqarisidan signal qabul qilib, avtomobil signalizatsiya moduliga uzatish orqali kengaytiradi. Ko'pgina tashqi antennalar shisha o'rnatilgan antennalardir. Bu shuni anglatadiki, siz stakanning tashqi tomoniga qabul qilgichni va bir xil oynaning ichki qismiga takrorlagichni o'rnatasiz. Signal oyna orqali uzatiladi, hech qanday teshik ochishga hojat yo'q va takrorlovchi simlar to'g'ridan-to'g'ri signal modulining antenna simiga uzatiladi.

Connect the siren. The siren should have two wires, one negative and one positive. Most car alarms output a positive siren, so connect the alarm unit to the positive wire of the siren and connect the other siren wire to a ground.[7]

Sirenni ulang. Siren ikkita simga ega bo'lishi kerak, biri salbiy va bitta ijobiy. Aksariyat avtomobil signallari musbat sirena chiqaradi, shuning uchun signal blokini sirenaning musbat simiga ulang va boshqa sirena simini yerga ulang.[7]

Connect the alarm sensors. The sensors are responsible for signalling that something is amiss and the siren should sound. You will connect the sensor wires from the car alarm to the wires that signal your door ajar or dome lights.[8] You can also connect them to the trunk and hood position sensors and the ignition switch depending on the features available with your alarm system.

  • It is recommended that you crimp these connections and do not simply twist them or use a wire nut.[9]

Signal sensorlarini ulang. Datchiklar biror narsa noto'g'ri ekanligini va sirena ovozi eshitilishini bildirish uchun javobgardir. Sensor simlarini avtomobil signalizatsiyasidan eshigingiz ochiq yoki gumbaz chiroqlari haqida signal beruvchi simlarga ulaysiz.[8] Shuningdek, siz signalizatsiya tizimida mavjud bo'lgan funksiyalarga qarab ularni magistral va kapot holati sensorlariga va kontaktni o'zgartirish tugmasiga ulashingiz mumkin.
Bu ulanishlarni burish va ularni shunchaki buramaslik yoki simli gayka ishlatmaslik tavsiya etiladi.[9]
