Note
When using 2-wire smoke
detectors on Zone 6, the
Two-Wire Smoke setting (in
program mode) must be
turned on before entering

Connecting 2-Wire Smoke Detectors
Zone input 6 can be set up (in program mode) to accept 12 VDC, 2-wire smoke detectors by the
following manufacturers:
• System Sensor models 2100D, 2100TD, 2100S, 2100TS, 2400, 2400TH
• Sentrol (ESL) models 429AT, 521B, 521BXT—models 521B and 521BXT require the
following dip switch settings: 1-on, 2-off.
!
Use only the 2-wire smoke detector models described above. Alarm signals from other
detectors may not be processed correctly if the panel has lost AC power and is operating
only from the backup battery.
Warning
When set up for 2-wire smoke detectors, zone 6 can handle up to 10 smoke detectors with 120
µ A maximum idle current per detector. Maximum total loop current allowed in an alarm condi-
tion is 80 mA. The maximum loop resistance for 2-wire smoke detectors connected to zone input
6 is 10 ohms, plus the 2k end-of-line resistor.
!
Panel terminal 16 (ZCOM/2W-) cannot be used as a common loop connection for any
other zones, when using Zone 6 for 2-wire smoke detectors.
Caution
Connect one or more 2-wire smoke detectors to the panel as shown in Figure 10.
