4. Mounting
There are location elements on the detector and the orientation base to ensure there is
only one installing position. There are two marks on point A and B of the orientation
base, and a mark on point C of the side face of bottom of the detector. When installing,
aligning the mark C of the detector to point A of the orientation base, rotate the detector
clockwise to point B, then the detector is installed.
The detector base is designed with anti-tamper function. After installing the detector
onto the base, twist a ST2.9X6.5 cross recessed pan head tapping screw into the hole
on the side of the base to prevent removal of the detector. Then the detector can only
be removed after twisting off the screw by a screwdriver. (Note: Please use this function
only when necessary to avoid trouble in maintenance and repair.)
5. Location and Spacing
1) The horizontal distance from the detector to the wall or the girder should not be
less than 0.5m.
2) There should not be any obstruction within 0.5m around the detector.
3) The horizontal distance from the detector to the blast hole of any
air-conditioner should not be less than 1.5m; that to the multi-hole ceiling blast
should not be less than 0.5m.
4) When installing detectors on corridor ceilings not wider than 3m, they should
be placed in the middle. The spacing should not be more than 15m. The
distance from the detector to end wall should not be more than half of the
spacing.
5) The detector should be installed horizontally. If it has to be installed aslant, the
gradient angle should not be more than 45

VI Testing
Warning: Power up only after all devices are well connected.
1. Before testing, notify the proper authorities that the system is undergoing
maintenance and will temporarily be out of service. Disable the zone or system
undergoing maintenance to avoid unwanted alarms.
2. Test the detector after installation and regular maintenance.
