Notes
[1] Use of FSRSI, FSRZI-A, and FSRRM is limited as follows: Three- and five-zone panels support 2 FSRSIs, 2 FSRZI-As, and 4
FSRRMs, ten-zone panels support 2 FSRSIs, 4 FSRZI-As, and 6 FSRRMs.
[2] See the FireShield UL and ULC Compatibility List (P/N 3100468) for the maximum number of detectors per IDC.
[3] See FireShield UL and ULC Compatibility List (P/N 3100468) for detector current ratings.
[4] Maximum current per IDC may not exceed 1.5 mA.
[5] Aux power supplied by panel cannot exceed 0.5 A. If more than 0.5 A is required, you must use a compatible UL/ULC listed
fire alarm power supply.
[6] When using an auxiliary power supply, you must connect the -24 OUT connection on the panel to the negative connection on
the auxiliary power supply. Refer to the installation section for more information.
