Note: This option can only be selected if N/C detection devices or contacts are used. Only one N/C contact can be con-
nected to each zone.
The following table shows zone status under certain conditions for DEOL:
Table 3-6 DEOL Loop Status
Loop Resistance
0 Ω (shorted wire, loop shorted)
5600 Ω (contact closed)
Infinite (broken wire, loop open)
11200 Ω (contact open)
3.1.9 PGM Wiring
Min/max operating voltages for devices, sensors and modules is 9.5VDC - 14VDC.
PGMs switch to ground when activated from the alarm controller. Connect the positive side of the device to the AUX+ ter-
minal and the negative side to a PGM terminal.
PGM 1, 3, 4 supply up to 50mA; PGM 2 supplies up to 300mA.
A relay is required for current levels greater than 50mA or 300mA. PGM2 can also be used for 2-wire smoke detectors, 24-hr
burglary input alarm.
Note: Use SEOL resistors on Fire zones only.

UL Compatibility ID For FSA-210B Series is: FS200
Note: For ULC listed installations, use FSA-210A and FSA-410A series.
3.1.10 Bell Wiring
These terminals supply 700mA of current at 10.4 - 12.5VDC for commercial/ residential installations. To comply with NFPA
72 Temporal Three Pattern requirements, section [013] Opt [8] must be ON. Note that steady, pulsed alarms are also sup-
ported.
