For descriptions of terminals 26-28, see the above de-

Note:
Non-power limited
wires must be isolated from power limited wires inside the
enclosure (at least a 1/4 inch spacing).

PROGRAMMING
Before programming and configuring the GEMC-NACXX
NAC circuits, we suggest you plan your installation by se-
lecting the zones to be used if you plan to install an NAC
Extender and / or an EZM. The usual practice is to select
the lowest zone numbers available. The EZM program-
ming instructions below use
EZM 1
(zones 9-12) as an
example; be sure to select the address numbers suitable
for your current installation.
