Optional 8-Channel Relay Card
Each member of the 46RX family also provides eight channel outputs for
signalling the state of associated transmitters. The channel outputs can drive
a bank of eight relays, mounted on a separate circuit card in the body of the
case. Each relay provides normally open, normally closed, and common
terminals.
The relay card, part number 4618EUR-55, is optional and must be purchased
separately.
Internal Sounder
The main circuit card in the lid carries a piezo electric sounder. Its terminals
are isolated from the other circuits on the card, and are available at a con-
nector at the bottom of the card. (See Figure 2.)
Next to the sounder terminals are the sounder output terminals. These can
be used to drive the internal sounder or an external sounder. The sounder
output comes on every time Common Output A or B comes on. See “Unit
Connection” for details of connecting the sounder output to the internal
sounder.
Expansion Units (4619-50)
If you want to receive more than eight channels from transmitters, you can
use 4619-50s as expansion units. The 4619-50 is physically similar to a
4618-50, except that it does not possess a radio receiver.
Once connected, each 4619-50 behaves like an independent unit, and can
be programmed separately from all the other units in the installation. You
should make sure that each unit has its own site code.
Connection
You may connect each member of the 46RX family to a control panel either
from the connectors on the main circuit card, or from the output connectors
on the eight-channel relay card
Figure 4 shows in detail the connectors available on the main circuit card.
