Q-Mux ID Modules


The Q-Mux is a low cost multiplex system.  Two wires are used to power the IDM sensor modules (i.e. Q-1C, Q-1A, Q-1CL, Q-1R, Q-I/O, Q-EOL, Q-SNP-RLY and Q-SNP-EOL) to send commands to the modules and receive their data.  Commands from the Q-Mux Node to the ID modules take the form of modulating Buss voltages between 0 and 10v.  The data returned from the modules is increased Buss current.

Each Q-Mux node can control up to 99 mix/matched IDM modules.  Up to 32 Q-Mux Nodes may be used in one system.  Total range of the Q-Mux system is 5,000 feet from the System 3505 PRISM LX to the last Q-Mux Node and 5,000 feet from the Q-Mux Node to the last ID module.  ID modules may be set to any address from one to 99.  ID addresses are stored on an internal EEPROM and can be changed by the Q-Mux Programmer (P/N 425184-0002).

The Q-Mux Option (P/N 010001-0094) or Q-Mux option w/32 Line Driver Rack P/N 010001-0099 and a minimum of one Q-Mux node (P/N 425190-0001) are required for the System 3505 PRISM LX.

Ethernet connectivity is available utilizing the Alarm-LAN option and VersAlarm controller to monitor the TCU-8 Nodes and IDM devices.  The SYSTEM 3505 PRISM LX must first be equipped with AlarmLan (P/N 020001-0121) and the desired number of VersAlarm, Q-MUX and IDM devices.  Using VersAlarm, the Prism LX can monitor 999 VersAlarm units and each unit can monitor 32 Nodes for a total of over three million IDM monitor or sensor points.

Each identification module (IDM) contains a processor, ROM, RAM, and EEPROM for field updating of variables such as addresses, etc.

All Q-MUX Products are ETL Listed and CSFM Approved

The IDM modules include:

Q-EOL:  Addressable module for monitoring dry contact closure. Requires user supplied 1.43 K-ohms resistor for supervision across input contacts. This is the required module for monitoring fire alarm Dsc00267acontacts.

Q-1R: Q-1R Addressable module that provides magnetically latching relay contact output under control of the System 3505 Prism LX (relay control option required) via Q-Mux Node. Relay activation Q1Ris maintained without power. If Q-Mux system is reset, relay will return to Normal state.

Q-1C: Digital addressable module for monitoring dry contact closure. EOL resistor not required.     Dsc00269a

Dsc00266aQ-I/O: Addressable module that combines features of the Q-1C with an open collector output transistor that may be used to control an indicator LED. EOL resistor not required.

Dsc00260aQ-1CL: Latching addressable module for monitoring fast-acting momentary dry contacts. EOL resistor not required.

Q-1A: Analog addressable module for monitoring 4-bit A to D conversion variable resistance inputs. Requires custom program at additional cost.SNP-RLY

 Q-SNP-RLY IDM MGNTC LTCH FORM C: The addressable Q-SNP-RLY provides a relay contact output under control of the Q-Mux Node.  To minimize the current draw from the Q-Mux Buss, a latching relay is used.  Power for switching the relay is stored in a capacitor in the module, thus dampening any disturbance to the Buss that could occur during relay switching.  When polled, the Q-SNP-RLY returns data at its address.  The data represents one of three states - relay contact Open, relay contact Closed, or Trouble (module malfunction).  The relay is rated at .5A 125VAC or 1 amps, 24VDC.  NOTE:  Whenever the SYSTEM 3505 Prism LX or the Q-Mux Node is powered up or reset, all Q-SNP-RLY relays will default to OFF.  IMPORTANT: Requires that the Relay Control Option (P/N 000001-0032) be added to the SYSTEM 3505 Prism LX to operate.Dsc00128a

Q-SNP-EOL-OC  ZN IDM W/OC CNFML CT: Conformal Coated for damp environments Q-SNP-End Of Line and Open Collector Identification Module is an individually addressable multifunctional IDM that can be used as a supervised End of Line input module to monitor dry contact closures and or as an open collector output module to provide a digital output to indicating LEDs etc.  Features include a Snap-on 10 pin Plug that allows easy snap in installation and testing.
