If you program PGM2 for use with a 2-wire smoke detector, you must wire it according to the
following figure:
Note: You must connect 2-wire smoke detectors in parallel.
Note: You can wire a maximum of 18 smoke detectors on a 2-wire loop.
Note: Do not use smoke detectors from different manufacturers on the same circuit as their operation may be impaired. Refer to the smoke detector installation sheet when you position detectors. For UL and ULC residential fire applications, use only the AUX2 output to provide power to smoke and CO detectors.
Note:
X in the detector name represents A for ULC and B for UL listed models.
The current rating for the DSC FSA-210B series is 35 mA.
The UL compatibility ID for the FSA-210B series is FS200.
For ULC listed installations, use FSA-210A series detectors or FSA-410A series detectors.
Wiring a CO detector or 4-wire smoke detector
The following table lists the maximum rating at 12 VDC of the hardwired CO detectors that are compatible with the PG9WLSHW8 converter.
Note: If you wire multiple CO detectors on the same loop, you must break the leads between each CO detector. You must power the supervision relay from the last detector in the loop.
To wire a CO detector or 4-wire smoke detector, see the following figures:
Note: You can manually configure PGM2 as a 2-wire smoke loop. If you configure any zone input as a fire zone, PGM2 is automatically set as a 4-wire smoke detector, and acts as a power reset. You cannot combine 2-wire detectors and 4-wire smoke detectors at the same time on the converter.
