NOTE 2: The wiring shown at the bottom of the diagram allows 24 hour tamper monitoring of all
detectors in one zone and of the zone circuit, with retaining the two-wire loop. It is not
recommended to connect more than 6 detectors in this way (not more than 7 x 4K7Ω±5% resistors).
More than 6 detectors may be connected to one zone in this way only if simultaneous activation of six
or more detectors is improbable (in disarmed mode also), otherwise it will cause a tamper alarm.
