Special Considerations: NOTE: Only one detector per zone shall be used, unless when in alarm the panel
switches the zone to a reverse polarity, non-current limited power supply. For
panels that do not provide this feature, a reversing relay, such as System Sensor’s
RR-2, may be used. When utilized with the 2100AT, it allows for more than one de-
tector to be utilized on a loop. Some panels may require the use of programmable
outputs. Refer to System Sensor literature for further information on the RR-2.
The 2100AT detector shall not be mixed with other 2-wire detectors on the same
zone.
–Due to the built-in temporal pattern, use this detector only with a non-coded
power source.

IMPORTANT: OBSERVE POLARITY
Polarity must be observed on the power and remote annunciator connections.
