A.2.2. ZONE DOUBLING with N.O. CONTACTS, without EOL RESISTOR, without TAMPER RECOGNITION
If some off your detection devices will use normally open contacts and your security installation does not require tamper or wire fault recognition, connect the
detection devices as shown in the next figure and ensure the zone wiring attributes are programmed as shown in the next table. This setup will communicate the
violated zones to the control panel which will display them on the keypads. Do not use devices with N.C. contacts in this zone setup, as this will cause the zones to
remain in alarm.
A.2.3. ZONE DOUBLING with N.C. CONTACTS, without EOL RESISTOR, with TAMPER RECOGNITION
If your security installation requires tamper (open circuit) detection, but it does not require wire fault recognition, connect the detection devices as shown in the
next figure and ensure the zone wiring attributes are programmed as shown in the next table. This setup will communicate the violated zones to the control panel
which will display them on the keypads. The control panel will also communicate any open loops (tamper trouble) as per Tamper / Wire Fault Recognition Options.
Do not use devices with N.O. contacts in this zone setup, as this will cause the zones to remain in alarm.
A.2.4. ZONE DOUBLING with N.O. CONTACTS, without EOL RESISTOR, with TAMPER RECOGNITION
If some off your detection devices will use normally open contacts and your security installation requires tamper (open circuit) detection, but it does not require
wire fault recognition, connect the detection devices as shown in the next figure and ensure the zone wiring attributes are programmed as shown in the next table.
This setup will communicate the violated zones to the control panel which will display them on the keypads. The control panel will also communicate any open loops
(tamper trouble) as per Tamper / Wire Fault Recognition Options. Do not use devices with N.C. contacts in this zone setup, as this will cause the zones to remain in
alarm.
