Overview

1. Detection Lens
2. Status Indicator
3. Bracket Slot

Status Indication

Blinks continuously. Motion detector performs a self-test.

Blinks once: Motion is detected.

Blinks twice: Motion detector has exited testing mode, and goes to power saving mode.

Blinks once per 3 seconds: Low battery, please replace battery.

PCB Layout

Tamper Switch: When the tamper switch is pressed, system will alarm immediately.

Infrared Sensors: The infrared sensors detect movement, and please make sure they are always clean.

Working Mode

Testing Mode

After a 1 minute self-test, the detector enters a testing mode. It detects once in every 10 seconds and emits alarm signal when motion is detected. This will last for 3 minutes and then switches into power saving mode.

Note: You can press the test button to enter testing mode too.

Power Saving Mode

If the PIR motion detector detects movements twice in 3 minutes, it automatically goes into asleep state. If there is no movement detected in next 3 minutes, it will switch from asleep state to arm. During the 3 minutes, the detector won't be active and send any signs to the control panel. As long as there is a movement detected within 3 minutes, the duration of power saving mode will be extended.

Detection Range

Side view

Pet-Immune Function

This sensor adopts a special design to improve detection accuracy. Pets less than 25kgs will not trigger the alarm.

Zone Mode of Sensor

Sensors can be placed in different zones for different requirements. Four different zones can be selected:

Normal zone. In arm or home arm state, the detectors set to normal zone work normally. Once intrusion is detected, the detectors trigger an alarm.

Home zone. When system is in home arm state, the detectors set to home zone are disarmed. The detectors set to other zones are armed. That is, partial arm.

Single delay zone. Sensors set to this zone will alarm at the specified time (which can set by yourself) after being triggered.

24 H zone: The detector set to 24 H zone trigger an alarm immediately when detecting intrusion, no matter the system is armed or disarmed.

Sensors in This Kit Zone Mode (Default Setting)
Door/Window Contact Normal Zone
FIR Motion Detector Home Mode Zone

You can set zone by changing the jumpers in detector. After the setting, detector can work in corresponding mode. It must be paired to the control panel again.

How to set:

Open the rear cover of the detector; change the array of jumpers on the zone setting to the corresponding position as below (Mind the direction of D0-D3):

Getting Started

Step 1. Insert SIM Card

Before inserting the SIM card, please perform the following steps:

1. Make sure the alarm system is powered off.
2. IMPORTANT: Remove the (default) code permanently from the SIM card.
3. Turn off the voice mail function if it is enabled.
4. Insert the SIM card into the SIM card slot; wait until the GSM indicator starts blinking once every 3 seconds; it means the network is connected.

SIM card requirement: 2G GSM SIM card with calling, SMS and caller display functions.

Step 2. Download the App

Download the App by searching keywords "GO2 Alarm" in the App Store or Google Play, and then create your own account.

Step 3. Add an Account

Step 4. Be Familiar with the Alarm System

Now you can tap | 📄 |, | 📄 |, | 📄 | to arm/disarm/home arm your system remotely. Tap [icon] and app will skip to messages interface automatically. After sending the SMS, you will receive a phone call from the control panel to leave a 10-second voice memo. Tap [icon] and app will skip to messages interface automatically. After sending the SMS, you will receive a phone call from the control panel to start a two-way talk.

Step 5. System Settings

Store Emergency Numbers & SMS Numbers

Emergency numbers are the phone numbers that will receive calls from the control panel when the alarm goes off.

SMS numbers are the phone numbers that will receive alarm SMS from the control panel when the alarm goes off.

IMPORTANT: After phone numbers are stored, only those numbers can modify the system settings. Commands from unauthorized phone numbers will be rejected.

Once an alarm is triggered, the control panel will dial the emergency numbers 3 rounds at most, if a phone is picked up with operation on phone button, the system will stop dialing.

Store Speed Dial Number

After the number is stored, you can dial this number immediately by pressing button once on the control panel.

Change Zone Name

10 remote controls and 50 sensors could be extended and the names of sensors are able to be edited.

This function aims at guiding users to identify the invasion location quickly by changing the sensor name. Their sequence in naming follows pairing order. For example, the first paired sensor is by default set to zone 1; the second paired sensor is by default assigned to zone 2, etc. In case of emergency, if you did not change the sensor name, this control panel will send SMS with zone number to user (e.g. Zone 1 Alarm).

Exit & Entry Delay Time

If you don't want to carry remote controls, you can set the exit or entry delay. Suppose entry delay was set at 30 seconds, the system will allow you 30 seconds to disarm the system before alarming. Suppose exit delay was set at 35 seconds, the system will allow you 35 seconds to leave before the system is armed. The "beep" is heard in every second to remind you to leave. The pace of reminding sound will speed up in last 15 seconds. Thus leaves you enough time to leave home without triggering the system.

Single Zone Delay Time

(To apply this function, you should change the zone mode of the sensor to single delay zone first. Please refer to "Zone Mode of Sensor" on page 9). After the time setup, the single delay zone sensor will delay to alarm when it is triggered

Comparison

For example: The exit & delay time is set at 30 seconds; single zone delay time is set at 40 seconds.

Sensor Arm Alarm
Normal and home mode zone Delay 30s to arm Delay 30s to alarm
Single delay zone Delay 30s to arm Delay 40s to alarm
24-H zone Always in arm state Alarm immediately

Disarm Password

The default disarm password is 1234. It is suggested to change the passcode for safety.

Setting through SMS

If you use a non-smart phone, you can set your system by sending the related SMS command codes to the SIM card in the control panel.

Item SMS Command Code
SMS menu 3, 72, 77
System setting inquiry 00
Disarm 0
