Amseco IS-S Isolator Techncial Note:
Amseco manufactured these units with bonding strips (ground wire). Connecting this wire will frequently cause a ground fault trouble to register on the common control to which the unit is connected. Potter recommends not connecting the ground wire when installing this unit. Ground fault detection will not be compromised by doing so. The IS-S is a ULC listed accessory (CAN/ULC-S527) to the HPS-24 mini-horn.

Please read our Terms of Use!

Note: It is important to note that the panel manufacturer (in Canada) must list compatible smoke detectors. Using a non-compliant smoke detector with any ULC® Listed fire alarm control invalidates its certification and could place the building occupants at risk. If you have questions regarding compatibility of a particular smoke detector (not shown on the list), please contact the manufacturer. Contact Information
