5.0 MODULES MOUNTING LOCATIONS
The
Main Chassis’
in a
HBB-1024
or
HBB-1072
Enclosure come pre-assembled with all power supply, main panel, and display
components and boards. The Expander Chassis has the display board pre-assembled. The
HPR-100 City Tie
Module or
HUDACT-100 Digital Communicator
may be added on the left side, as shown in the figure on the following page. These
Modules connect directly to the dedicated P2 connection in the upper-left corner of the Main Fire Alarm Module.
Circuit Adder
Modules
are installed from right to left using the supplied stand-offs, as shown in the figure on the next page, with the first Module
plugging its 26 pin ribbon cable into P5 on the Main Fire Alarm Module, and using the included HMD-579 four wire power cable
as described in the Module Settings section. A second Circuit Adder Module would connect by plugging its 26 pin cable into the
matching socket on the previous module to the right, and by installing the supplied HMD-579 four wire power cable as described
in the appropriate Module Settings section.
In a
HBB-1072
Enclosure with an
Expander Chassis
, there are two each of long extension cables for the 26 pin ribbon cable
(
HMD-575
) and for the four wire power cable (
HMD-580
) included. Circuit Adder Modules are installed as on the Main Chassis,
from right to left in two tiers (back then front). These are cabled as in the Main Chassis, except that the first module on the back
tier to the right connects via HMD-575 and HMD-580 extension cables to the second module in the Main Chassis, and the fourth
module on the front tier to the right connects via HMD-575 and HMD-580 extension cables to the third module on the first tier to
the left. In other words a continuous right to left, bottom to top, and back to front installation order (see the figure on the next
page).
To enable communication from the Main Fire Alarm Module to all of the Circuit Adder Modules, it is necessary to remove the
Continuity Jumper
on JW6 (near P5, the Circuit Adder Module Connector) on the Main Fire Alarm Module. This jumper plug must
be installed on the
Continuity Jumper
on the last installed Circuit Adder Module (see the appropriate Module Settings section
to verify the location of the
Continuity Jumper
on a particular Circuit Adder Module). Only the LAST Circuit Adder Module should
have a jumper plug on its
Continuity Jumper
; all others must be left without a jumper plug !!
There needs to be enough
Display Points
for each circuit on an Adder Module, and these are assigned during Configuration (see
Configuration Section) in the order in which the Adders are electrically installed (the order in which they have their cables
connected to each other). Both the number of points available for each Display Type, and the number required for each Circuit
Adder Module Type are described in the Module Settings Section.
As good practice, it is recommended that Circuit Adder Modules be installed in the order of Detection followed by Signals, followed
by Relay Modules.
