Protege System Controller Reference Manual

Zone Expander Polling Time
The polling time defines how often the Zone Expander checks in with the Protege System Controller. If a Zone
Expander fails to check in, it triggers its associated communication failure trouble zone (ZXxxx:08) and the
trouble zone for a general module communications failure.
To enter a polling time (008 to 250 seconds), use the keypad as explained in section Entering Decimal Numbers
(see page 341) and press [ENTER]. By default the Zone Expander polling time is set to 250 seconds. Setting a
polling time below 60 seconds should only be done for zone expanders that are in a non-secure area.
ZX001 Polling
time: 250 secs
i
For UL and ULC listed installations you MUST set the polling time to 180 seconds or less.
Zone Expander Module Options
Options that relate to the zone expander module can be set using option entry.
ZX001 Module
[--------]
To modify options, use the keypad as explained in section Entering Data Options (see page 344).
Option 1 - High Current Charging
• Enabled the zone expander will enable 700mA charging in the power supply system.
• Disabled the zone expander will enable 350mA charging in the power supply system.
Option 2 - Bell Over Current Requires Acknowledge
• Enabled the bell over current condition will remain until the trouble condition is acknowledged in the system
controller at which point all bells (if more than one bell has a problem) will be cleared and reset.
When installing a system to conform to UL or ULC requirements this option must be enabled.
i
• When the option is disabled and a bell over current condition occurs the bell output will be turned off. It will
be turned on one minute later, if the problem still exists it will be turned off again, this process is repeated
until the bell is deactivated by the area or other function within the system.
Option 3 – Use Alternate Resistors
• Enabled the zone expander will use alternate EOL configured resistors (2K2 and 6K8).
• Disabled the zone expander will use the normal 1K and 1K resistor configuration.
Option 4 – Invert Module Tamper
• Enabled the zone expander will invert the module tamper input allowing a normally open (door closed)
tamper switch to be used.
• Disabled the zone expander will use the standard normally closed (door closed) tamper switch.
Option 5, 6, 7 and 8 - Reserved
• Reserved do not modify
Enabling/disabling or modifying the settings of reserved options is not recommended.
