① Mains Supply Input: The alarm host adopts AC 220V ± 10% 50Hz input, and the
input terminal is connected in series with a 0.5A fusion tube.
② External Backup Battery Input: The host adopts DC12V7Ah external backup
battery input.
③ External Siren Output: A DC 12V siren (current: <0.6A) can be connected to
the alarm host.
④
Local Call Phone Line Socket: It is used to connect with local call phone line
(also called outside line). The local call phone line connected with this socket is not
allowed to connect with phone or other communication device in parallel.
⑤ User Phone Socket: User phones shall be connected with user phone socket by
a double-ended phone line. To take up phone line, user phones must be led out from
user phone socket of the alarm host.
⑥ RS485: The keyboard, wireless receiver and network module adopt RS485
communication. The head and end of line must have 120 ohm resistor to achieve
reliable communication. Note: Some of our products are equipped with 120 ohm
resistor.
⑦
Wired Defense Zone Input: Z1~Z8 represents input of defense zone 1-8, which
respectively corresponds to defense zone number 000~007. Defense zone 000 is a
tamper zone intended for the host, which is applicable to connect emergency alarm
buttons. When there is any wired zone in alarm host system, defense zones 000~007
are not allowed to learn code with wireless detectors.
⑧
Several Connection Methods of Wired Detectors: Z terminal is the positive
terminal of alarm signal return from wired defense zone. GND is the negative
terminal of alarm signal return. Wired defense zones can be used together with wired
detectors to achieve short circuit/cut-off alarm functions. If a wired detector is
operating under open circuit conditions, its loop shall be connected in parallel with a
2.7K Ω resistor. If a wired detector is operating under short circuit conditions, its
loop shall be connected in series with a 2.7K Ω resistor. If the defense zone loop is
not used, it shall be connected in parallel with a 2.7K Ω EOL ( End of Line) resistor .
If several wired detectors are required, they can be connected in series, in parallel, or
combination of both.
