The GEM-P1664 can use conventional 12 VDC 4-wire smoke detectors. To use
them, select fire zone programming option and do not select 2-wire smoke
detector programming option for the desired fire zone (refer to the GEM-P1664
Programming Instructions). Set JP3 to the position as shown, if zones 7 or 8 are
to be used.
Four wire smoke detectors may be connected to any programmed fire zone (1-8)
as shown, within the panel. If the Zone Doubling is used (see EZ Zone Doubling
Configuration), the respective complementary zones (9-16) are disabled when 4-
wire smoke detectors are connected to zones 1-8. If external EZMs are used for
zones 9-64, then 4-wire smoke detectors may be connected to any programmed
fire zones (9-64).
Power must be obtained from terminal 25 and 6. If Fire Alarm Verification is
desired to reset the smoke detectors, select this option for the desired fire zone.
Two-wire smoke detectors can only be connected to zones 7 and 8. To use
them, select fire zone programming option and select 2-wire smoke detector
programming option for the desired fire zone 7 or 8 (refer to the GEM-P1664
Programming Instructions) and set JP3 to the "2-WF" position as shown.
Connect the 2-wire smoke detectors as shown.
If the Zone Doubling is used (see EZ Zone Doubling Configuration), the
respective complementary zones (15 & 16) are disabled when 2-wire smoke
detectors are connected to zones 7 & 8.
If Fire Alarm Verification is desired to reset the smoke detectors, select this
option for the desired fire zone (zone 7 or 8).
