Although it is an advanced and reliable security system, it does not offer absolute guaranteed protection against
burglary, fire, or other troubles. The limitations are as follows:
1. Intruders may get access to unprotected openings may not alert people if they are installed in an improper
position.
2. The system will disable without power.
3. Alarm warning devices such as bells may not alert people if they are installed in an improper position.
4. Telephone line used to transmit alarm signals may be out of service for any reason, or can not perform
communication normally for vicious attack.
5. Unsuitable installation position of detectors. If smoke detector is installed in an improper position, it is not
for smoke to enter the detecting area. Because of doors or walls, it is hard for the detector to detect fires
rooms, e.g. the detector in the first floor can not sense fires in the second floor.
6. Lack of maintenance may lead to the system disable. Weekly testing is necessary to ensure the system work
normally.
