Planning the Cable Installation
TD100 sensor cables must maintain a minimum spacing of 1 m (3.3 ft), and maximum of 2 m
(6.6 ft). Spacing throughout the sensor run must be consistent. 1.5 m is standard for all military
applications.
The Terrain Defender Sensing Cable (TDSC) is sold in a 400 m (1312 ft) length on a spool.
Order a pair of 400 m spools (P#600-04356) to create a roughly 400 m sensor length, or any
zone size larger than 200 m (656 ft). A single 400 m spool can be used to cover zone sizes of
200 m or less. The dimensions of a single TDSC spool are 81 cm (32 in) W x 40.5 cm (16 in) H,
and the weight is 104 kg (230 lbs). Care must be taken when transferring and preparing to
unspool and install the cable.

Once spacing has been determined for a site, that spacing must be consistent throughout the
system.
