4-WIRE SMOKE DETECTORS

4-WIRE SMOKE DETECTOR WIRING

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).
