6.4 Alarm Input Connections

The ZTX6 has the same number of alarm inputs as camera inputs (they are not dedicated to

the corresponding camera input). On each module they are numbered on the graphic from 1

to 8 (see Figure 5 on page 17). They are actually numbered in the same way as the

cameras, the base unit (ZTX6/8M2) contains inputs 1 to 8, the first additional module

(ZTX6/MOD) contains inputs 9 to 16 (but labelled 1 to 8), the second 17 to 24 and the third

25 to 32 (see Figure 5).

Electrically the alarms operate from volts-free relay closures (or openings) and the inputs

can be individually configured in the on-screen menus to respond to normally-open or

normally-closed contacts.

• Remove the 5-way terminal block

• Connect from each terminal to your alarm relays (see Figure 2)

• Group the returns and lead them into the common connection

The alarm-input connections are normally-open as a default. If you are connecting normally-

closed alarms do not connect your alarm terminal-blocks yet wait until you have changed the

alarm configuration in the on-screen menus.

6.5 Alarm Output Connections

The base unit has 2 alarm output contacts as shown below. Each alarm input on your ZTX6

can be set to trigger one or the other, both or neither in the on-screen menus. The output

relays can be set to normally-open or normally-closed individually in the on-screen menus.

They are normally-open as a default.

CAUTION: Normally-closed alarm-output-relays are reliant on a power-supply.

When the unit is switched off they immediately revert to the open state.

The relays switch a maximum of 30V, 2A each.
