Immediate | 即时

An input type that will immediately go into alarm when trigger when the system is armed.

Independent Floating Thresholds (IFT) | 动态阀值调节

Eliminates electrical environmental disturbances by ensuring alarm thresholds are always kept within predetermined limits.

Inertia is the resistance of any physical object to any change in its state of motion. This includes changes to the object's speed, direction, or state of rest. This is used in shock sensors as the vibration changes the resistance in the electrical circuit and this can be analysed to determine an alarm.

Input | 输入

An input is a device that is monitored by the panel. This is typically a PIR, magnetic contact, dual technology detector, shock sensor etc.

Input Device | 输入设备

The actual device that the system is monitoring. Typically a PIR, magnetic contact etc.

Input Types | 输入类型

In order for the system to know how to react when an input is triggered, it needs to be given an input type.

Installation | 安装

Mounting of panel and components including initial start-up.

Instant | 即时

An input type that will immediately go into alarm when trigger when the system is armed.

Instant Two-Way Device Control (ITDC) | 瞬间双向设备控制

This enables the instant wake-up and instant sleep of each wireless device on the system to preserve battery.

Interior Protection | 室内防护

The interior area of the building is protected here, in particular those areas that a burglar would, in all likelihood, have to pass through; generally PIRs and magnetic contacts.

Internal Alarm | 室内报警

The alarm is only sounded in the building, the external sirens are not activated.

Internal Sounder | 室内警号

Transducer for inside area, generally just audible; triggered by DC.

Internal Speaker | 室内扬声器

Transducer for inside area, purely audible; triggered by AC.

Intruder | 入侵

An input type that will immediately go into alarm when trigger when the system is armed.
