The basic zone configuration for the GEM-P1632 is 8 zones. Connect as shown above to terminals 13-24. Normally
Closed (N.C.) devices may be wired in series or Normally Open (N.O.) devices may be wired in parallel. Use the 2.2K
Ohm end-of-line (E.O.L.) resistor in each zone, if selected in programming (refer to the GEM-P1632 Programming In-
structions). Zones 1-8 can be selected for a “Fast Loop Response (50 ms)” or a “Normal Loop Response (750 ms)”.
Other zone options include Zone Type (Entry/Exit, Interior, 24 Hour Protection, Trouble and Fire), Instant, Chime, Area
Selection and PGM Output selection.
##
The control panel zone configuration may be expanded from 8 to 16 zones without the use of EZM Modules. To do so
simply select “EZ Zone Doubling” in programming (refer to the GEM-P1632 Programming Instructions) and connect
zones as shown above. NOTE: If both zones in a zone-pair configuration (ex: zones 1 & 9 in the above diagrams) are to
be used, then normally closed devices must be wired to both zones. The 3.9K EOL resistor must be placed across the
terminals of the higher zone and the 2.2K EOL resistor must be placed at the end of the loop of the lower zone.
If Normally open zones for fire or panic devices are required, then the lower zone (2.2K EOL resistor) must be used and
the higher zone (3.9K EOL resistor) must not be programmed for any area.
WARNING: Assigning a fire zone or keyswitch zones to a zone doubled control will disable the respective complimentary
zone. For example, if zone 8 is assigned as a fire zone, it will disable zone 16. If zone 3 is assigned as a fire zone, it will
disable zone 11.
