Ohm (Ω) | 欧姆
The unit of measurement of electrical resistance. The value of resistance through where a potential difference of one volt will maintain a current of one ampere.
Omit | 忽略
This used to describe the act of stopping an input from becoming armed/set. A wired input will still pick up an intruder but the alarm panel will not react to it - a wireless input will become dormant.
One-Push-To-Learn | 一键学习
A feature in all Pyronix wireless devices that means learning devices onto the system can be done in seconds. Simple one button learning feature for easy installation.
Open & Close | 开放&关闭
A service that is provided for monitored accounts. Each time the alarm system is armed or disarmed, a special code is sent to the monitoring station which records the lime and who the user of the system is. If the system is not armed by regular closing times or is disarmed out of opening times, a phone call is made to either the client or the police.
Open | 开路
When an electrical circuit is not complete it is referred to as 'Open'. Depending on the wiring choice, this could be an alarm or a tamper.
Open Collector | 开集极电路
An open collector is a common type of output found on many integrated circuits (IC), which behaves like a switch that is either connected to ground or disconnected.
Optical 3D System | 光学3D系统
Improves the detection of moving targets, ensures more precise signals can be received from the PIR and allows protection of the area below the detector (creep zone).
Output | 输出
An output is a signal from the panel to indicate to another device to operate. This is usually a voltage that triggers a wired bell, a garage door, a signalling device etc.
Output Types | 输出类型
In order for the system to know trigger an output, it needs to be given an output type.
