5.4 Releasing Programming Options
The HCA panel provides water releasing and two agent releasing programming options. You must use
either the HCA-4 or HCA-8 if you are using releasing features as all releasing programming options
require the use of zones 1 through 4. Note that if you want to use a disconnect switch for the releasing
circuit, you must use the HCA-8! Both the water and agent releasing configurations use zones 2 and 3 for
cross alarm functions and zone 4 as a manual release alarm function; zone 5 of the HCA-8 is used for the
disconnect circuit (see section 5.4.4). The zone 1 function depends on the releasing option chosen as
detailed in the following sections.
Select option 4 from the main programming menu to reach the programming options for releasing.
5.4.1 Agent Release 1
The
Agent Release 1
option configures the panel for the cross zone releasing configuration shown in
figure 5.1. Figure 5.2 is a truth table that shows the cross alarm or manual release inputs that are needed
for agent releasing to occur.
