11.4 Released
relay
The released relay will operate when the module enters the released condition, triggered by activation of
the monitored activation inputs. The released relay will also operate if the panel enters the released
condition via the released pressure switch input.
The Released relay can be disabled at access level 2 via the menus on the ECU.
11.5 Abort
relay
The Abort relay will operate when the panel is in the aborted condition, activated via an abort switch
input.
11.6 Extract
relay
The extract relay will operate when selected at access level 2. This provides a means to vent a room of
extinguishing gases but prevents the gases from being vented during a discharge.
To switch on the extract relay, operate the
ENABLE CONTROL
keyswitch and then press
ENTER
on the
ECU on which the required extract relay is fitted.
The LCD will show:
Press the
DOWN
button until the display shows:
Press
ENTER
to turn the extract output on.
The LCD will change to the following:
Pressing
ENTER
again will turn the extract off.
12 Connection and configuration of Status indicators and Ancillary boards
Important!
The ECU should not be powered during the connection of status indicators or ancillary boards.
Status indicators and ancillary boards require a four-wire connection from the associated ECU to the
corresponding data and power, in and out terminals. Two of the cables carry power to the units (24V)
and the other two carry data.
A four core cable suitable for carrying RS485 data should be used. If this is a twisted pair cable then one
twisted pair should be used for the data connections and the second pair used for the power
connections.
Each status indicator and ancillary board has a 3-bit DIL switch and must be allocated a unique address
between 1 and 7.
The ECU is able to distinguish between status indicators and ancillary boards so it is possible to have a
status indicator set to address 1 and an ancillary board set to address 1 if desired.
