2.4 Input Circuits
The control panel has 4-16 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 Initiating Device Circuit (IDC) designed to accept any normally-open contact devices and
conventional 2-wire, 24 volt smoke detectors.
All zones may be configured for general fire alarm applications.
Four-wire smoke detectors may be connected to any zone. Resettable power is provided via RESETABEL DC24V
Terminal. Refer to the 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.
FIGURE 2-4-1: Class B Initiating Device Circuit Connections
FIGURE 2-4-2: Supervisory Input Circuit Connections
Any switch or push button can be connected in supervisory
terminal IN1, IN2.
When terminal IN1, IN2 has the DC12 voltage, the panel
Supervisory LED turns on to indicate that there is a supervisory
alarm.
