Okay…I think this may be helpful to anyone who may want more info or are in information overload concerning the IXL Series.
This is basically a SparkNotes version of the IXL Datasheet from FireAlarmResources.com
Cerberus Pyrotronics IXL----Device Type Cheat Sheet
IXL: Main PCB, Keypad, and Enclosure. 2 SLC Loops, 2 NAC’s, Battery Charger, and relays for Alarm, Trouble. Supervisory, and Degrade Operations.
IXL-EXP: Expansion Module: Provides two additional SLC Loops for a total of four loops and a total of 256 Addressable Devices supported.
ICon: I-Series Adressable Interface: Facilitates bidirectional communication between the IXL and I-Series Addressable Initiating Devices and IXL Addressable Auxiliary Devices. Total of 4 ICons supported per IXL.
CZI: Collective Zone Interface Module: Addressable Monitor Module available in Low-Power (Contact Devices only, “CZI-L”) and High-Power (Smoke/Beam Sensor Compatible, “CZI-H”) configurations as well as Class A (“4”) or Class B (“2”) Wiring Styles (CZI-L2S, CZI-H2S, CZI-L4S, CZI-H4S). Total of 256 CZIs supported per IXL.
CE: Addressable Control Element: Output Control Module that can be used as a Form C Relay (dry contact) or Remote Audio/Visual Signal Relay (activation a remote NAC Controller). Total of 224 CE Modules per IXL.
LAN, RAN. LPI, RPI: Alphanumeric Annunciation and Serial Printer Modules: LAN=Local Alphanumeric Annunciator/Printer Interface (installed in IXL enclosure), RAN=Remote Alphanumeric Annunciator/Printer Interface (installed in RAN-SB Backbox), LPI=Local Printer Interface, RPI+Remote Printer Interface. Total of 16 LAN/RAN/LPI/RPI Modules per IXL.
LED-1, LED-2: LED Annunciator: Provides “conventional” LED Annunciation. Available in Black (LED-2) and White (LED-1). Total of 24 Annuciators per IXL.
GAD, RRD: Remote Graphic Annunciator Driver (GAD) and Remote Relay Driver (RRD): GAD allows the IXL to control a user-supplied Graphic Annunciator. RRD allows the IXL to control user-supplied Relay Units. Total of 24 GAD Modules per IXL.
GenCon: Generic Switch Control Module: Provides 8 Automatic or User-Controlled Generic Switch Functions. This is often used for HVAC Shutdown or similar applications. Total of 4 GenCon Modules per IXL.
RemCon: Remote User Control Module: Provides the user with the ability to remotely Acknowledge, Reset and Drill an IXL System. RemCom also contains all of the LED indicators contained on the IXL Interface, an internal sounder, and a key switch to enable/disable operation. Total of 16 RemCon Modules per IXL.
INS-EVI: Remote Voice Evacuation Relay: Allows the IXL to activate 8 Alarm Inputs on the Cerberus Pyrotronics CPV-90 Voice Evacuation System. Recognized by the IXL as a Control Element. Total of 16 INS-EVI Modules per IXL.
RemSwitch: Remote Switch Module: Provides standalone keyswitch-operated remote Acknowledge, Reset or Drill functionality when used in conjunction with a CZI Module. Total of 256 RemSwitch+CZI Modules per IXL.
INS-AUX: Auxiliary Relay Module: General Purpose Relay Module to be mounted in the IXL enclosure. INS-AUX can be programmed to activate immediately or after a designated time or alarm sequence.
Hope this is helpful!!!
