Defining Zone Parameters using the “By Category” Option
For a specific parameter type, this lets you to define it accordingly for multiple
zones (as you go from one to another, scrolling through all zones in the system).
 To define zone parameters using the By-Category option:
1. From the installer Programming menu go to: 2 > 1 > 2
(Zones > Parameters > By Category).
2. Scroll to arrive to the parameters and their respective options to modify.
Parameters: Label, Partition, Type, Sound, Termination, Loop Response,
Advanced. Then press OK ( ) to confirm after each selection. Use the numeric
keys to enter the zone number (or numeric values) where needed.
Defining Zone Termination Resistance using the “Resistance” Option
Regardless of which method was used to define zone parameters (One-by-One, or
By Category), if you had specified end-of-line termination in the Termination
parameter (for wired zones only), you have only specified what type of
termination configuration to apply for the wired zone – EOL, DEOL, TEOL, NC, or
NO. In the Resistance option, you now define the termination resistance value(s)
for the wired zone.
If using a zone expander (16-zone, 8-zone, single-zone), during installer
programming, in addition to defining the termination resistance for all the relay
detectors connected to it – which can be any combination of EOL, DEOL, TEOL
detectors, you also need to define the termination resistance compatibility for the
zone expander itself, according to the “highest” level of any relay detector you
intend to connect to it. For example, if you have EOL, DEOL and TEOL detectors
connected to a zone expander (or if you have only EOL and DEOL detectors, but
want to leave open the possibility of adding a TEOL detector to the zone expander
in the future), you will need to set the zone expander’s termination resistance
values to TEOL – the “highest” level.
Default termination resistance values for RISCO relay detectors are:
 EOL (end-of-line): 2.2K Ω
 DEOL (double end-of-line): 2.2K Ω, 2.2K Ω
 TEOL (triple end-of-line): 4.7K Ω, 6.8K Ω, 12K Ω
NOTE: For retrofit installations, you can define the resistance compatibility
according to the resistors already installed in the relay detectors.
