INCORPORATED
There is an internal jumper (see Figure 5) which selects the negative or positive lead of the battery
input to power the alarm input optoisolators. For positive ground systems (factory default) the
jumper should be in the
- Station Battery
position. This selects the proper polarity voltage input to
power the optoisolators. For negative ground systems, the jumper must be in the
+ Station
Battery
position. If this jumper is in the wrong position, an alarm input will not be asserted when
the input is connected to station ground.

ALARM INPUTS:
You will need a 50-pin male ribbon connector (Amp CHAMP type) for the 32
inputs. It is best to order a pre-assembled cable assembly from a company such as Grayhill. One
easy option is to use a cable with a 50-pin connector at one end and a 66 block (punch-down
block) at the other end. The punch down block can be mounted on the wall, and all the station
alarms brought to that block. The pin assignments for the I/O connectors are detailed at the end of
this document.
CAUTION
: The alarm input connector pin assignments do
NOT
follow typical Telco pin pairing.
There are not enough pins to allow each of the 32 alarm points to have a separately paired ground
wire. Follow the pin assignments for the connector detailed at the end of this document (Table 8).
RELAY OUTPUTS:
You will need a 50-pin male ribbon connector for the 16 form-C relay outputs
(Amp CHAMP type) for the outputs. It is best to order a pre-assembled cable assembly from a
company such as Grayhill. One easy option is to use a cable with a 50-pin connector at one end
and a 66 block (punch-down block) at the other end. The punch down block can be mounted on
the wall, and all the outputs can be connected at that point.
CAUTION
: The relay output connector pin assignments do
NOT
follow typical Telco pin pairing.
There are not enough pins to allow each of the Normally Open & Normally Closed contacts of the
16 control relays to have a separately paired ground wire. Follow the pin assignments for the
connector detailed at the end of this document (Table 7).
ANALOG INPUTS:
A single DB25 female connector is used for the analog inputs. Its pin
assignments are detailed in
Table 9
. These inputs will not be functional unless the optional analog-
