5. Installation Guide
All Enforcer peripherals;
LCD keypads, readers,
expanders etc. are
connected via the D1-,
D2+, D3 and D4 terminals.
This is an example of what
a typical Enforcer bus may
look like.
General Principles:
NOTE 1: No alarm system
cable should be run with
other cables carrying AC or
digital signals.
NOTE 2 : The cables should
be protected by the use of
grommets where
appropriate.
NOTE : For greater than 1000m range a standard isolated RS485 repeater is required.
IMPORTANT NOTE: If an expansion module with a power supply on board is connected, the
D2+ terminal MUST NOT be connected between the main bus and module.
