The PDRP-2001, PDRP-2001C, and PDRP-2001E fire alarm control panels (FACPs) are compatible with the System Sensor i3 Series conventional smoke detectors that transmit signals to the FACP to indicate important status conditions, such as low temperature 45°F (7.22°C) or required maintenance. This control panel is compatible with conventional input devices such as waterflow devices, tamper switches, 2-wire smoke detectors, 4-wire smoke detectors, pull stations, and other normally open contact devices. The PDRP-2001, PDRP-2001C, and PDRP-2001E panels supervise wiring, AC voltage, battery charge, and battery level. An installed waterflow detector, compatible smoke detector, or any normally open fire alarm initiating device will activate audible and visual signaling devices, illuminate an indicator, display alarm information on the panel’s LCD, sound the piezo sounder at the FACP, activate the FACP alarm relay, and operate an optional module used to notify a remote station or initiate an auxiliary control function. Four outputs are programmable as notification appliance circuits (NACs) or releasing circuits. Three programmable Form C relays (factory programmed for alarm, trouble, and supervisory) and 24 VDC special application resettable and non-resettable power outputs are also included on the main circuit board. Unless otherwise specified, the information in this data sheet applies to both the 110/120 VAC and 220/240 VAC versions of the panels.
