SPECTRA SERIES 11
2.9 SINGLE ZONE INPUTS
Detection devices such as motion detectors and door contacts are connected to the control panel's zone input
terminals. Figure 2.5 on page 11 demonstrates single zone input terminal connections recognized by Spectra. Once
connected, the associated zone's parameters must be defined. For details refer to Zone Programming on page 19.

2.10 DOUBLE ZONE INPUTS (WITH ATZ OPTION ONLY)
Enabling the ATZ feature (see page 25) on the Spectra 1728 or 1738 allows you to install two detection devices per
input terminal. The ATZ feature is a software oriented feature. Therefore, there is no need for extra modules. Simply
connect the devices as shown in Figure 2.6. Devices connected to input terminals must be assigned to a zone and
the zone's parameters must be defined. Refer to Zone Programming on page 19 for more information. The status of
each zone will be displayed on the keypads and the control panel can send separate alarm codes for each zone.
