Cable Routing
The cables should run in grounded conduit or at least 2 ft. (0.7 m) from
AC power, fluorescent lights, or other high energy sources.
I
MPORTANT
:
Physically separate all data cables from power lines. If you use
conduit, do not run data cables in the same conduit as power cables or certain
door strike cables, for example, strike voltage greater that 42 V or Magnetic
door locks without EMI suppression.
All cables must conform with the following regulations: National
Electrical Code; NFPA 70; Local electrical codes; Canadian Electric
Code C22.1 (installations in Canada); BSI Standard BS7671, latest
edition (installations in Great Britain).
Make all cabling using good wiring practices and allow sufficient cable
length to allow service loops at cable terminations in the enclosure.
Wiring Input Devices
Tamper Switch Wiring
The tamper switch connects to a general purpose input point. To be
operational, the tamper switch must be wired to one of the unused input
points on any S321-IP in the enclosure and programmed.

When wiring more than one S321-IP, use the same type of hook-up wire and
communications wire to connect subsequent controllers.

Refer to reader manufacturer’s recommendations when using UL-listed readers. In the
absence of other recommendations, consider these cable specifications taking into
account the number of conductors that will actually be needed for installation.
