During supervision, signal outputs are isolated from signal inputs by open contacts allowing consideration for use with SCIF applications (Sensitive Compartmented Information Facilities).Relay contacts isolate signal inputs from outputs during supervision and do not monitor signal presence signal inputs sources will need to be monitored separately.Signal IAMs are not compatible with 4010 fire alarm control panels IDNet communications. 4100U compatibility requires Software Revision 11.11.01 or higher.Signal coding of horn/strobe control, strobe synchronization, or other coding is provided by the signal input coding at the Signal IAM via IDNet addressable communications is not supported.NAC output is rated 0.5 A for Special Application or Regulated 24 VDC Appliances, or for audio operation (12.5 W 25 VRMS, 35 W 70.7 VRMS) and can be wired Class B or Class A see additional information on page 2, specifications section.Signal output notification appliance circuit (NAC) wiring is supervised and connected to the signal input under IDNet communications control.Signal IAMs provide additional selective signaling for Simplex® 4007ES, 4008, 4010ES, 4100ES, and 4100U Series fire alarm control panels:
