Installing The Control Panel; Mains Power - Urmet 1043/550 Guia De Inicio Rapido

FIELD MODULE INSTALLATION
Firstly, install the field modules (detectors, manual buttons, input and output modules, audible and optical fire alarms) as shown in the
fire alarm system design.
Connect the field devices using specific fire alarm wires that meet the following specifications:

Suggested cable:

Maximum length:

Cable total resistance:
The wiring of each detection line of the system can be in class A (loop line) or class B (open line) according to the design and
regulations of the country where the fire alarm system is being installed.
Analyses the critical situations which, in the event of a line failure (short circuit and/or line opening), could cause an excessive number
of devices to go out of service.
For the mechanical, electrical and location installation of each device, refer to the design and technical documentation accompanying
the device and follow the manufacturer's information and instructions.

INSTALLING THE CONTROL PANEL

The control panel is intended for indoor use and designed to be mounted on the wall. It must be positioned at a height that facilitates
both keypad use and optimal viewing of the display.
Use four screws and 6-mm dowels (not supplied) to fix the control panel to the wall.
Several openings are provided in the bottom of the casing for passing through the wires coming from the field, such as the detection
lines and the various low-voltage connections with other devices in the system.
A pre-cut hole is provided in the bottom of the casing for passing through the mains power wire.

Mains power

Use the pre-cut hole in the lower part of the control panel casing to pass through the mains power wire.
Fix the mains power wire to the bottom of the casing using the cable tie (supplied).
Connect the phase (F), neutral (N) and earth (GND) conductors to the respective terminals of the AC/DC converter power supply unit.
It must be possible to cut off the mains power (both phase and neutral) upstream using a suitable external disconnector with a contact
separation of at least 3 mm.
It is advisable to keep the power wires separate from the low-voltage wires and connections of the fire alarm system.
Batteries
There are two sealed lead batteries with a capacity of 12Ah and a voltage of 12V inside the control panel.
The battery to be used must:

Be of the VRLA (Valve Regulated Lead Acid) type

Have an enclosure with flammability class UL94V-1 or better

Be compliant with standards IEC 60896-21:2004, IEC 60896-22:2004
The batteries must be connected in series and connected to the +BAT and -BAT terminals of the control module (MCC) using the
supplied wires.
After establishing the electrical connection, apply the temperature probe on the batteries and secure them with the clips on the bottom
of the casing.
