PART 13: ZONE EXPANSION MODULE
The following options and features are only available to program when a
Zone Expansion Bus Module
has been connected to the Spectra
control panel’s communication bus as shown on page 13. The Zone Expansion Modules provide you with up to 4 (SPC-ZX4) or up to eight
(ZX8) additional hardwired inputs and one normally open 50mA PGM output (ZX8 only). A PGM is a programmable output that toggles to its
opposite state (i.e. a normally open PGM will close) when a specific event has occurred in the system. For example, a PGM can be used to
reset smoke detectors, activate bells or strobe lights, open/close garage doors and much more. For information on how to connect the refer
to Figure 2-8 on page 13. For information on how to program the PGM, refer to sections 13.4 to 13.6 of this manual.
The Zone Expansion Modules do not support the ATZ feature.
13.1 ZONE INPUT ASSIGNMENT (ZONE MODULE)
Section [651]: Options [1] to [8] (see below)
After connecting the hardwired detection devices to the Zone Expansion Module’s inputs, you must enable the zone
inputs that are being used. To do so enter section [651] and enable the options that correspond to the module’s
zone inputs as shown below. When the option is OFF, the input is disabled. The enabled zone inputs are then
automatically assigned to an Expansion Input. Each Expansion Input represents a specific zone in the system
depending on the type of Spectra control panel being used and whether the ATZ option is enabled. Once the
module’s zone inputs have been assigned, their associated zones must be programmed as described in Zone
Programming on page 20. You cannot assign more than 8 additional zones to the Spectra System.
Do not assign detection devices from different modules to the same expansion input. For example,
do not assign a wireless transmitter to section [601], then connect a detection device to input Z1 of
the ZX8 and enable option [1] in section [651].
13.2 EOL ZONES (ZONE MODULE)
Section [650] - Options
Option [1] OFF = Zones do not use EOL resistors (default)
Option [1] ON = Zones require EOL resistors
If all detection devices connected to the Zone Expansion Module have input terminals that require 1K
Ω
end of line resistors,
turn on option [1]. For more information on the use of EOL resistors, refer to Single Zone Inputs on page 11.
13.3 TAMPER RECOGNITION (ZONE MODULE)
Section [650]: Options
Option [2] ON = Tamper Recognition Disabled (default)
Option [2] OFF = Reserves Input “Z1” As Tamper Switch Input
The Zone Expansion Modules do not come equipped with a tamper switch. Although, if your installation requires tamper
recognition, enabling this feature will reserve input terminal Z1 of the zone Expansion Module as a tamper input. This allows you
to connect a tamper switch to input Z1 as shown in Figure 2.8 on page 13. When a tamper is detected on the module, it will send
a Zone Tamper report code to the control panel via the communication bus. The Zone Tamper report code will originate from the
zone defined by the Expansion Input (001-008). Please note that the corresponding zone must be programmed (see page 20).
If enabled, do not connect anything other than the tamper switch to input terminal Z1.
