2.4 Input Circuits
The control panel has 10 zone input circuits. The maximum loop resistance limit for each input circuit is 100 ohms.
All field wiring of each zone is supervised for opens and ground faults. Both conditions are visually and audibly
annunciated.
Each zone is a Class B Initiating Device Circuit (IDC) designed to accept any normally-open contact devices and con-
ventional 2-wire, 24 volt smoke detectors.
All zones may be configured for general fire alarm applications. In addition, zones 9 and 10 can be configured as fire
alarm zones or supervisory alarm zones.
Four-wire smoke detectors may be connected to any zone. Resettable power is provided via TB2 Terminals 3 and 4.
Refer to the Fire•Lite Device Compatibility Document for a list of compatible smoke detectors.
It is allowable to mix an assortment of device types (i.e. smoke detectors, heat detectors, pull stations, etc.) on any
zone. If, however, alarm verification is employed on zones 1, 2 and 3, only smoke detectors should be installed on
these three zones.
