1.1 General description

1.1.1 Luminous indicators

State indicators show in every moment the working condition of the equipment or

system. They are located at the left side of the screen.

a) PWR: “POWER”. Green

On: when the equipment is powered from any of the possible power sources.

b) EMG: “EMERGENCY”. Red

On: when the equipment is in an emergency operating state (voice alarm), either

because of a manual or automatic activation from the CIE (Fire Control and Indication

Equipment) from any of the available emergency inputs.

Simultaneously, when the indicator is turned on, a continuous audible warning will

be issued. This warning tone can be silenced by the button “BACK”.

c) FLT: “FAULT”. Yellow

On: when the equipment is in failure state. This indicator activates automatically

after detecting failure in any of the supervised functions.

Simultaneously when the indicator is turned on, an intermittent audible warning

will be issued. This warning can be muted by the "BACK" control. It will also stop when

the emergency microphone is used.

d) SYS: “SUSTEM FAULT”. Yellow

On: In case of any system fault like configuration memory lost, messages lost,

internal device failures this led will turn on.

1.1.2 Controls

a) Scroll controls

They are at the right side of the display. They allow

the user to move around the Use and Configuration

menus. The central button is the function ENTER/OK,

that can be used to accede to the menu and the

operations that need confirmation.

Illustration 2: Control panel

b) Direct access controls

i) OK: Makes the indicator test by pressing the button for 2 seconds .

ii) RESET/RST: Pressing this button for 2 seconds allows the user to restart the

operating condition of the equipment when it is in either emergency or fault state.

iii) BCK:

•Menu navigation: go up one level / return. Pressing this button for 2 seconds

returns to the initial screen and restarts the access level.

•Mute function of acoustic alarm when it is sounding.

1.2 User profiles. Access levels. Password

Access levels define the following user profiles that can operate with the

equipment/system. Each access level has different permissions to different menu

options, with level 1 being the lowest and level with the greatest number of available

options.

Generally, access levels allow to:

•Level 1(L1): EN5 element visualization and use of PA System(*)

•Level 2(L2): System management and emergency functions. Password: 0002

•Level 3(L3): System configuration and advanced functions. Password: 0003

•Level (L ): Accessible only by the manufacturer.

Each screen that needs access to the user level required for the function to which you

want to accede will require it. A higher level user or password will be able to access

lower level functions.

To accede with a certain level of access or to configure the access mode, the Login

menu is used. You can select between access mode by confirmation, or -digit password

access.

button during 2 seconds, and it will go back to the start screen as a level 1 user.

(*) PA Block: An access for the password can be configured for PA controls where the

functions volume, routing, etc. are. (See 3. )

2 INSTALLATION

The equipment allows the installation in wall or rack, and in vertical or horizontal

orientation. Installation accessories are available to facilitate the installation procedure.

To fix the equipment to the supports, of the 8 outside screws of the equipment shall

be removed. From each pair of screws the one that is closer to the side where the

support will be placed is removed. The clamping wings are inserted through the

corresponding perforations and the screws that fix the equipment are placed preventing it

from falling.

2.1 Orientation change

To change the orientation, the screws that fix the front of the equipment to the

chassis are removed. This way, the front is released, and the orientation can be changed

so that the controls are accessible according to their final position.

2.2 Inputs and outputs

In this chapter, the connectors of the ONE series are described.

The enclosure has 7 pre-cut holes for the entry and exit of the wiring, easily removed

with a screwdriver. Its size is 36mm, which matches the size of the racors for 32mm

tubes.

2.2.1 Power supply

The equipment has redundant power supply according to EN5 - thanks to the battery

charger accessory. The AC power supply range is universal type 90-2 0 V ~ input and

frequency 50 or 60Hz, with integrated Power Factor Correction (PFC).

The backup source consists of a battery that is installed internally with the included

battery charger by activation.

a) Main power input

The power connection is made directly

by wiring it to the interior of the equipment,

it must include the power disconnection

elements externally. To manipulate the

equipment, the external power must be

disconnected.

There is a three-pole 1.5-2.5mm cable

connector marked for Phase, Neutral and

Ground. The cable can be inserted and

removed thanks to the push button.

Illustration 4: Power connections

b) Disconnection switches

These switches cut the power path of the power supply and the battery. They help to

avoid the danger of sparks when connecting the battery and it's useful for restart the

equipment completely.

2.2.2 Battery installation

Before installing the battery it is recommended to switch

off the equipment using the switches in the supply circuit.

This system allows to mount the battery safely and avoiding

unwanted short circuits.

The equipment has a cavity for 12V sealed lead-acid

batteries with a maximum size of 167 (height) x181 (width)

x76 (depth) mm.

The equipment consumes 9Ah of battery for 2 h in stand-

by and 8Ah for one hour in evacuation at maximum power. With the recommended

battery brand YUASA NP17-12I we have 17Ah, enough to comply with stand-by and

evacuation needs.

Additionally, a 25 Amps safety fuse is available for the battery input located on the

supply plate.

Battery assembly

Unscrew the fixing part and release the flange that holds the cable for transport.

Connect the battery, put in the housing and fix it again. Remember that lead acid

batteries should not be installed inverted.

2.2.3 Fire central interface

The emergency activation interface is indicated for interconnecting with fire control

and indication equipment. All input connections are supervised in the event of failure in

the transmission line. Said interface is composed of three sections.
