4. CONNECTING
4.1 Relay Module MR8
MR8 is a supplementary module which is located outside the MAG8Plus Alarm Panel
box. The MR8 contains 8 changeover contact relays.
When using all 16 zones, the MAG8Plus needs two relay modules.
The technical specifications of the MR8 module relays are described in item 2.2.
Configuring 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
configuring 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 first zone relay is activated by the
module relays after the button
upon an alarm event.
Performance of the MR8 Module Relays
The MR8 Relays are activated upon an alarm event (fire) in the respective zone they are
connected to.
• If a sounder delay is set in the main control panel, this delay will also reflect on the relay
activation of the first alarm - it shall delay by the same duration.
• The relay activation delay is eliminated by pressing the
and the sounders are immediately enabled.
• Once a fire 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 first entered the
alarm mode.
• The relay will restore its normal state only after the initial start-up of the control panel.
