MAG816 - Installation and Operation Manual 13

4. CONNECTING

4.1 Relay Module MR8

MR8 is a supplementary module which is located outside the MAG816 Alarm Panel box.

The MR8 contains 8 changeover contact relays.

When using all 16 zones, the MAG816 needs two relay modules.

The technical specications of the MR8 module relays are described in item 2.2.

Conguring the MR8 outputs

Should zones numbered 1 to 8 be used, a jumper is set at outputs 1÷8 of the MR8

mother board; should the jumper be set at outputs 9÷16, zones numbered 9 to 16 will

be used - Figure 17.

The MR8 relay contact type (normally closed or normally open) is determined by

conguring the NO/NC outputs. Setting the jumper at the NO output will normally open

the contact; setting the jumper at the NC output will normally close the contact - Figure

17.

Special jumper J1 - when this jumper is set, the rst zone relay is activated by the

module relays after the button

(see item 6.2) on the control panel is pressed

upon an alarm event.

Performance of the MR8 Module Relays

The MR8 Relays are activated upon an alarm event (re) in the respective zone they are

connected to.

• If a sounder delay is set in the main control panel, this delay will also reect on the relay

activation of the rst alarm - it shall delay by the same duration.

• The relay activation delay is eliminated by pressing the

button - the relay and

the sounders are immediately enabled.

• Once a re signal has been generated and there is a sounder delay set off, the following

MR8 relays will be activated immediately.

• The activation of the respective relay is immediately after the sounders are activated.

Where there is any delay, it shall apply only to the relay of the zone that rst entered the

alarm mode.

• The relay will restore its normal state only after the initial start-up of the control panel.

Pressing the

button will not restore the relay.

In order to operate together with the MR8, the MAG816 Fire Alarm Panel

must be in Master Panel mode - a jumper is set at the Master position.

The connecting between one Relay Module MR8 and Master Panel MAG816 is shown

on Figure 18.

The connecting between two Relay Modules MR8 and Master Panel MAG816 is shown

on Figure 19.
