Senstar Corporation 24000 User Manual

The transmitter and receiver units have been designed to mount on a 9 cm (3 1/2 in.) OD post. A 2.44 m (8 ft.) 
post is typically used with 91 cm (3 ft.) of the post buried in a concrete footing. 

The foundation for the mounting posts in normal soil should be at lease 91 cm (3 ft.) deep and 61 cm (2 ft.) in 
diameter. If soil conditions are such that a non-shifting foundation is questionable, then a larger footing should be 
considered. In areas where extremely low temperatures may cause frost heaving, use a truncated pyramid base 
foundation.

When the foundation concrete cures, there is a possibility of it pulling away from the post, allowing for rotation of 
the mounting post. Placement of rebar below ground level in the foundation and through the post is suggested to 
prevent this.

A weatherproof junction box in the vicinity of each unit's mounting post is the best location for terminating the 
primary power supply. A double-row terminal block allows this to become a convenient junction box for those 
lines running back to an alarm reporting panel. Conduit for the power supply junction box should be installed in
