VEGA MULTI-MODULES
GENERAL DESCRIPTION
Generally speaking, the Vega multi-module series is a family of microprocessor controlled interface devices permitting the monitoring and control of auxiliary devices. These are loop powered devices that operate according to the Vega analogue-intelligent protocol and are characterized by low current consumption; their particular design allow an easy and fast installation. A channel is a multi-module’s sub-device through which monitoring and control of analogue-loop-extraneous auxiliary devices is exerted by the analogue control panel. Multi-modules are, by a matter of fact, multi-channel devices. In detail Vega multi-modules are:
HFI-IO-404-01 ­ is composed by 4 input channels and 4 form C outputs.
HFI-IO-422-01 ­ is composed by 4 input channels, 2 supervised output channels and 2 form C output channels.
HFI-IO-602-01 ­ is composed by 6 input channels and 2 form C output channels.

SHORT-CIRCUIT ISOLATOR
The multi-module has a built-in bidirectional isolator designed to provide short circuit isolation and functional protection features for the analogue-intelligent loop. When activated, the isolator will “cut out” the adjacent loop’s section where the short occurred; on the other hand, all functions of the devices situated on opposite loop’s section of the multi-module will be unaffected and operate normally.

When the short is removed, the multi-module restores power to the isolated loop’s section and its devices.

Multi-modules are equipped with two LED indicators: one is dedicated to the input channels and the second one is dedicated to the output channels (picture 9); these are green/red/amber three-colour LEDs. When all channels are in normal conditions, the status of the first input
channel (considering a sequential order based on the loop addresses given to the channels) is signalled on the input LED, and the status of the first output channel is signalled on the output LED. If one channel alters its condition (fault or alarm), then the related LED signals the condition of it. If more than one channel is in a not-normal condition, the first one in addressing order is signalled.

ADDRESSING

Multi-modules are analogue-addressable devices. Each multi-module type can be assigned more than one address, this depends by the
choices made by the installer of the fire security system and its design. If installed on a loop, the multi-module must be assigned at least one address, with a value ranging from 1 to 240, which corresponds to the first input channel that is always active and cannot be disabled: all the other ones can be activated or deactivated by the installer, depending
on his needs, from the control panel (if it has been implemented with such control feature); each multi-module takes up to 8 addresses sequentially, and no inactive gaps are allowed between two active addresses.
Similarly to every Vega device, each active channel can be controlled by the control panel and must have a unique address. Automatic addressing can be performed on this kind of devices (consult the analogue-intelligent auto-addressing feature described on the related application notes).

Alternatively to control panel’s addressing and management, the first address of multi-modules can be set by using a special hand-held programming unit; for more information about manual addressing, please, refer to the programming unit’s instruction manual.

NOTE: The multi-modules can hold up to 8 active addresses. The address assigned by the programmer always relates to the input channel; to the remaining active channels are automatically assigned the consecutive addresses.

INSTALLING THE MULTI-MODULES
For specific information regarding detector and device’s spacing, placement and special applications refer to your specific national standards.
1. Select the position of the multi-module before installing and fixing it.
2. Securely fix the device’s box to the wall with the provided screws (see picture 5 and 6).
3. Multi-module’s device box is designed with three cable entry knockout holes, present on each lateral side, allowing sealed, cable gland fitted, loop and auxiliary device’s cables to be connected to the device and, at the same time, to preserve the IP protection rating (picture 7). Fit the cable gland (or glands) to the cables.
4. Fit the cable’s gland (or glands) into the device box’s cable entry (or entries).
5. Feed the cables into the box, giving them a sufficient length.
6. Connect the cable’s terminals to the device’s terminal blocks as indicated in the wiring paragraphs.
7. After installing all multi-modules and other loop devices, apply power to the loop in accordance with the control panel’s installation instructions.
8. Test multi-module’s effectiveness and reset the system as described in the TESTING and RESET paragraph.
9. Position the front cover onto the device’s box and tight it with the supplied screws until a good seal is obtained (picture 8).

WARNINGS AND LIMITATIONS

Our devices use high quality electronic components and plastic materials that are highly resistant to environmental deterioration. However, after 10 years of continuous operation, it is advisable to replace the devices in order to minimize the risk of reduced performance caused by external factors. Ensure that this device is only used with compatible control panels. Detection systems must be checked, serviced and maintained on a regular basis to confirm correct operation.
Smoke sensors may respond differently to various kinds of smoke particles, thus application advice should be sought for special risks. Sensors cannot respond correctly if barriers exist between them and the fire location and may be affected by special environmental conditions. Refer to and follow national codes of practice and other internationally recognized fire engineering standards.

WIRING THE MULTI-MODULE – GENERALITIES The multi-module must be: a) connected to the analogue loop, as any other analogue device b) connected to the monitored and/or controlled auxiliary device (or devices). In picture 9 are illustrated the terminal block’s schemes of the various types of multi-modules. Picture 10 illustrates specifically the connection of the M1 terminal block’s set, common to all multi-modules devices, for the connection to the analogue-intelligent loop.

THE SUPERVISED INPUT CHANNEL AND ITS WIRING

External device

This channel provides monitoring of normally open contact fire alarm devices (picture 11). This channel is capable of supervising an adequate “end of line” resistor (REOL) fitted into its terminals; purpose of this supervision is to distinguish between the following conditions:
a. Normal condition. b. Alarm condition. c. Short circuit fault condition. d. Open circuit fault condition.
RSW guarantees the alarm current when the switch is closed.

THE SUPERVISED OUTPUT CHANNEL AND ITS WIRING
This channel (picture 12) provides control of external, loop-unrelated auxiliary devices such as fire shutters; it performs two main functions:

External power (-)

a) supervises the connection to the controlled external load through an “end of line” resistor (REOL)
b) supervises the presence of an external power supply for the output.

External power (+)

The purpose of the supervision functionality of this channel is to distinguish between the following conditions:

a) Normal condition.

b) Short circuit fault condition on the load’s “loop”. c) Open circuit fault condition on the load’s “loop”.

Channel’s output (-)

d) External power supply shortage fault condition; this can be caused by a short or open circuit on the power supply “loop”, or by the VEXT value under a certain threshold.

THE FORM C OUTPUT CHANNEL AND ITS WIRING
This output channel provides relay’s double pole contacts changeover for the control of auxiliary devices (picture 13 illustrates a wiring example). This nonsupervised form C output is controlled and can be switched over by the control panel.
This channel type is characterized by 3 terminals:
a) C: “common” terminal
b) NC: “normally closed” terminal
c) NO: “normally open” terminal
By default, C is switched over the NC terminal; when activated, C is switched over the NO terminal.
Please note that due to the non supervised nature of this output, only technologic devices can be connected to it (fire shutters hold / release devices and so on).

Picture 13 – form C output channel’s wiring
TESTING In order to try out the functionality of the installed multi-module, the following tests must be performed: All active output channels – alarm test: trigger an alarm condition on the control panel (by a call-point or sensor in the installed system): the control panel will activate or switch-over the multi-module’s output (or outputs). All active input channels – alarm test: activate the external device: the control panel must trigger a system alarm. All active supervised input and output channels – fault tests: generate open and short circuit conditions on the supervised channel’s loops: the control panel must signal one or more fault conditions. After each test the device must be reset by the specific command on the control panel (see the RESET paragraph). All devices must be tested after installation and, successively, on a periodic basis. RESET To reset the multi-module from an alarmed or a fault condition, it is necessary to: 1) solve the cause of the abnormal condition 2) reset the system from the control panel.
