Note:
For multiple unit connections, the leads between CO detectors must be broken. The power supervision relay must be powered
from the last detector in the loop.
Wireless CO detectors are also available. When installing wireless CO detectors, use only model PG9913
UL
, PG8913, PG4913, or
PGx933. An HSM2HOSTx (x=9

/8/4) wireless receiver or HS2LCDRFPRO wireless keypad are required when installing wireless
CO detectors. For more details on these wireless devices, refer to their respective installation manuals.
Note:
Use only
