2.12 Double Zone Connections
Enabling the ATZ feature (see section 4.8 on page 16) allows you
to install two detection devices per input terminal. The ATZ feature
is a software oriented feature. Simply connect the devices as
shown in Figure 8. Devices connected to input terminals must be
assigned to a zone and the zone's parameters must be defined.
Please refer to Zone Programming on page 11. for more
information. For UL listed installations, use EOL resistor part
#2011002000.
Figure 8: Double Zone Connections
2.13 Keypad Zone Connections
Each LED and LCD keypad has one hardwired input terminal
allowing you to connect a detector or door contact directly to the
keypad. For example, a door contact located at the entry point of
an establishment can be wired directly to the input terminal of the
entry point keypad instead of all the way to the control panel.
Even with the ATZ feature enabled in the control panel,
only one device can be connected to the keypad’s
hardwired input terminal. Tamper is not recognized on
keypad zones. The keypad zone follows the control
panel’s EOL definition.
A device connected to the keypad’s input terminal must be
assigned to a zone in the control panel and the zone’s parameters
must be defined (see Zone Programming on page 11.). The keypad
will communicate the status of the zone to the control panel via the
combus. The detection device is connected as shown in Figure 3
on page 3.
2.14 Keyswitch Connections
Connect the keyswitches to the keypad, control panel, or Zone
Expansion Module's hardwired input terminals as shown in Figure
9. Once a keyswitch is connected, it must be assigned a keyswitch
zone and its parameters must be defined as described in
Keyswitch Programming on page 17.

2.15 Fire Circuits
Connect the smoke detectors used in the security system using
any of the following methods. Smoke detectors connected to the
control panel or zone expansion input terminals must be assigned
to a zone in the control panel and the zone's parameters must be
defined as a Fire Zone. For more details, refer to Zone
Programming on page 11.
2.15.1 Smoke Detector Installation (2-Wire)
PGM1 can be defined as a 2-wire smoke detector input (see
section 10.4 on page 31) enabling smoke detectors to be
connected as shown in Figure 10 on page 8. Fire Zones must use
a 1k
Ω
EOL resistor. If there is a line short or if the smoke detector
becomes active, whether the system is armed or disarmed, the
control panel will generate an alarm. If the line is open, the “Zone
Fault” trouble indication will appear in the Trouble Display and will
transmit the appropriate report code to the monitoring station (if
programmed).
2.15.2 ESL CleanMe
TM
Installation
The Digiplex control panel supports the use of ESL smoke
detectors that have the CleanMe
TM
feature. The ESL smoke
detectors are connected exactly like standard smoke detectors as
shown in Figure 10 on page 8. Please note that you should avoid
connecting more than 20 ESL smoke detectors. When an ESL
