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

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
