Frequently Asked Questions - ZM 2100 RCF

How do I set the priority of inputs on the ZM 2100?

Use the INPUT 1 to 4 PRIORITY SET dip-switches (D1 and D0) on the rear panel. Options: Graduated (D0=0, D1=0): input 1 over 2, 2 over 3-4, etc.; I/LOCKED (D0=1, D1=0): only the first served input is open; O/RIDE (D0=0, D1=1): the next used input always overrides the previous one; MIX (D0=1, D1=1): all inputs open and mixed.

How do I connect paging microphones to the ZM 2100?

Connect up to six BM 2006 paging microphones via the PAGING UNITS INPUT (RJ45) in a daisy-chain configuration. For all-call paging, use a BM 3022 microphone connected to the MIC 1 RJ45 port (with chime enable). Microphones with XLR connectors can use the MIC 1-4 inputs.

What amplifier configurations are supported by the ZM 2100?

The ZM 2100 (no internal amplifier) supports two modes via the SINGLE/DUAL AMPLIFIER dip-switch: Single amplifier: one external amplifier handles both paging and background music for all zones; Dual amplifier: one amplifier for background music and another for paging. You can also use one external amplifier per zone (0 dB zone commutation).

How do I add more zones beyond 6?

Add up to 8 ZE 2200 6-zone expanders via the dedicated RJ45 port (CONNECT TO ZE 2200 ONLY). Each expander adds 6 zones and can share the main unit's music program or insert a local source. For paging additional zones, use BE 2012 keyboards linked to a BM 2006 paging microphone.

How do I configure the logic inputs (GPI) and outputs (GPO)?

Use the LCD menu: press MODE then select TRIGGER. Choose among ZONE TRIGGER (GPI activates corresponding zone and GPO), HIGH TRIGGER (GPI not linked to 24V OUT activates GPO), or LOW TRIGGER (GPI linked to 24V OUT activates GPO). There is also a BGM TRIGG input to give priority to AUX INPUT 3.

How does the emergency override work?

The EMERGENCY INPUT has the highest priority and overrides all others. It accepts a 100 V line or a 0 dB balanced audio signal. Adjust the level with the EMERGENCY INPUT LEVEL control. The input features VOX function (automatic signal detection above a threshold).

How should I clean the ZM 2100?

Use a dry cloth to clean the external parts. Do NOT use solvents, alcohol, benzene, or other volatile substances. Ensure the unit is disconnected from power before cleaning.

How do I set the chime for paging?

Use the MIC 1 CHIME setting dip-switches (D1 and D0) on the rear panel. Options: No chime (0 0), 1-tone chime (0 1), 2-tone chime (1 0), 4-tone chime (1 1). The chime is triggered by a BM 3022 microphone or by shorting RJ45 pins 3 and 6 of MIC 1.

How do I connect backup batteries to the ZM 2100?

Connect a 24 V DC supply (e.g., two 12 V batteries in series) to the DC 24 V removable connector. Observe polarity (+ and -). Always use rechargeable batteries sized for the maximum load. The unit will operate on battery power if AC mains fails.

How do I upgrade the firmware on the ZM 2100?

Set both FIRMWARE UPGRADE dip-switches to ON. Connect a PC to the RS 232 port (9-pin D-sub) and use RCF service software. After upgrade, set both dip-switches back to OFF for normal operation.

ZM 2000 SYSTEM DESCRIPTION

ZM 2000 is a versatile multi-zone sound system suitable for paging and background music. The system main unit is available in two models:

- ZM 2124 includes a preamplifier with 6-zone selection and a built-in 240W amplifier - ZM 2100 includes a preamplifier with 6-zone selection (no internal amplifier).

ZM 2124 and ZM 2100 have input connectors for sources and can manage priority and route the two buses to the system zones.

A system can include just a single main unit (either ZM 2124 or ZM 2100) for a basic 6-zone system.

ZM 2124 is mostly indicated for small systems, where the required power per zone is limited.

It includes an output level control for each of the 6 zones powered by the internal 240W amplifier. An additional external amplifier is needed to keep the music programme in zones not involved by paging.

ZM 2100 allows you to choose either a power-sharing configuration by using one or two external amplifiers (the second is needed to keep music in zones not paged) for all the 6 zones or to use an amplifier (or more) per each zone.

Up to 8 ZE 2200 6-zone expanders can be added in order to increase the system zones up to 54.

Each ZE 2200 offers the possibility to either share the main unit music programme or insert a local source.

All ZM 2124 / ZM 2100 main units and ZE 2200 expanders are based on a dual bus architecture, where the first bus is mainly dedicated for selective / all-call paging, while the second bus is for music distribution (or other signals).

All units have a toggle button per zone to turn on / off the second bus (music) and logic inputs / outputs (GPI / GPO) to interface the system with other devices.

ZM 2124 and ZM 2100 inputs:

• 2 MIC and 2 MIC / LINE (with configurable priority among them).
• 2 local (plus 1 through RC 2946 remote control) selectable AUX on the music bus.
• 1 additional AUX INPUT with priority and sent to the paging bus.
• A dedicated paging input for up to six BM 2006 paging microphones.
• An emergency audio input.

Inputs 1 to 4 and AUX have level and tone controls on the front panel.

Paging can be preceded by a selectable chime.

All ZM 2124 / ZM 2100 main units and ZE 2200 expanders can be powered by mains (115 / 230 V) or 24 V dc. All are provided with 19" rack mounting accessories: 3 rack units for ZM 2124 / ZM 2100, 1 rack unit for ZE 2200.

BM 2006 are suitable paging microphones to complete the system, with 6-zone keys plus 'All-Call' and 'PTT'. Up to six BM 2006 can be daisy-chained to a main unit.

BE 2012 are additional keyboards that need to be linked to a BM 2006 paging microphone and each adds 12 zone keys.

One or more BE 2012 are necessary to page zones related to ZE 2200 expanders.

It is possible to link up to four BE 2012 to reach the maximum system capability of 54 zones.

BM 3022 are all-call paging microphones (on the music bus) that can be directly connected (by sharing the same line) to the main unit MIC 1 input.

All paging console connections are made through CAT5 FTP cable.

RC 2946 remote controls are wall-mount devices for AUX input selection and zone activation (music bus).

ZM 2100 only: when using one or more external amplifiers per each zone, link every external amplifier input to its respective zone loudspeaker output, which is here used as a 0 dB audio output (see the next 'ZM 2100 - 0 dB zone commutation' manual section).

DC 24 V (removable connector)

Input for secondary 24 V dc power supply (i.e. batteries) that will maintain the operation of unit if the AC power (from mains) is temporarily unavailable.

Double check the correct polarity + / - when connecting.

ZM 2100 - 0 dB ZONE COMMUTATION

ZM 2100 allows to use an external amplifier (or more) per each of the 6 zones.

All ZM 2100 internal relays are (in this case) used to switch 0 dB audio signals (instead of 100 V lines).

ZM 2100 needs to be set to the dual amplifier mode through its respective dip-switch [28].

CONNECTIONS

Link the PRE OUT 1 34 directly to AMP IN 1 63 and PRE OUT 2 34 directly to AMP IN 2

64

Link the A ÷ F 65 outputs to the external amplifier inputs.

NOTES:

• Custom cables need to be made.
• All ZM 2100 contacts labelled '100 V' are here used for the signal.
• All ZM 2100 contacts labelled '0' are here used for the ground.

RACK INSTALLATION

ZM 2124 and ZM 2100 are designed for table-top use, but can also be mounted into 19" rack cabinets by fixing (though screws) their respective rack ears.
