Connections to Building’s Fire Panel (See Figure 7)
The Fire Panel should be connected to J5, J12, J14 and J16 at the bottom of the panel’s main PC board.
The connectors as shown will mate with the panel’s independent internal dry relays to signal alarms to the
Fire Panel. Under normal conditions these relay dry contacts are OPEN, but in the event of an alarm they
will be CLOSED (shorted). This mode of operation can be reversed for individual relays. This is a very rare
requirement but the switches on DIP SW3 enable this feature as shown in Table 4 on Page 12. If all primary
power and all battery backup power is depleted, all of the relays will be closed (shorted), indicating an
alarm condition.
The single pole relays are rated for a max current of 200 ma and 30 Volts (DC). If these values are exceeded,
self-resetting fuses in series with the relay contacts are triggered to protect them.
Figure 7 shows how the Fire Panel’s end-of-line resistors (EOLR supplied by panel provider) can be installed
on J6, J11, J13 and J17 if they are not installed elsewhere outboard of the DASAlert Panel on the wires
connected to the Fire Panel.
Removal of the Knockouts
There are a total of 15 ports on the top, bottom, sides and back of the Panel that are compatible with
standard ½” conduit fittings. All of these ports (except the three in the back) are plugged with plastic
knockouts that can be removed as shown below. Three spare plugs are included with the accessories.
TO REMOVE KNOCKOUTS, CUT THE RETAINING TABS OFF FIRST
