IMPORTANT: OBSERVE POLARITY

Polarity must be observed on the power and remote annunciator connections.

Electrical Ratings
System Voltage (nominal):	12 or 24 VDC
Minimum:	8.5 VDC
Maximum:	35 VDC
Maximum Ripple Voltage:	30% of nom. Voltage (peak to peak)
Standby Current:	50 ∝A average, 100 ∝A maximum

	(If used, the RA400Z Remote Annunciator operates within the specified detector
	alarm currents.)
Reset Voltage:	1.8 VDC minimum
Reset Time:	0.6 seconds maximum
Start-up Time:	30 seconds maximum (after 60 sec. reset)
EOL Relay:	A77-716B, 12/24 VDC
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.
