Channel reading currently within threshold limits.
Upper or lower Warning limit reached or exceeded.
Upper or lower Critical limit reached or exceeded.
- 38 -
SmartZone Gateway E24 User Manual
Input Sensors – Defaults
The Input Sensor Defaults menu allows configuration parameters for input sensors of
specific types to be defined and applied to all inputs of that type.
The types of input sensors are:
l Temperature
l Humidity
l Analog (Voltage)
l Open/Close Contacts (digital inputs)
The configurable defaults are described below.
Calibration Offset
The value entered here alters the actual reading of a sensor by the amount specified.
- 39 -
SmartZone Gateway E24 User Manual
For example, if a Calibration offset of 6 was used and a sensor's true reading was 36,
the indicated reading used for display and alarm purposes would be 42. This works the
same way for both temperature and humidity sensors.
Hysteresis Value
The hysteresis default value to be applied to sensors is specified here. The value specified is an offset from a sensor's threshold values.
For example, a hysteresis value of 5 would mean that, in the case of an Upper Control
Limits alarm, the alarm value would have to reduce to 5 below the threshold value before
another alarm is issued.
Please see Appendix B: Hysteresis Demystified for detailed information.
Limits and Traps
You can set default values for sensor alarm thresholds here. You also can set the default
settings for alarm threshold traps here.
The following thresholds can be set:
l Upper Control Limit
l Upper Warning Limit
l Lower Control Limit
l Lower Warning Limit
You can apply default trap settings for all of these thresholds. With the trap box deselected, no SNMP alarm traps will be generated, even when an alarm condition exists for
that threshold.
Repeat Timer
The repeat timer causes alarm traps to be reissued after a specified amount of time if the
alarm condition persists.
Setting the repeat timer to 0 will disable the repeat traps.
- 40 -
SmartZone Gateway E24 User Manual
The defaults that can be set for Open/Close contacts differ from the Temperature and
Humidity settings.
Normal State
Normal state specifies the condition in which a contact is considered to be in a Normal,
Non-alarmed state.
Devices such as smoke alarms and air conditioning units often have normally open contacts. To receive alarm indications from these types of units would cause alarms to be
issued when a monitored contact closes.
Setting normally closed in the case of a rack or cabinet door would cause an alarm condition when the door was opened.
Trigger Type
The trigger type defaults for Open/Close sensors are specified here.
The three available options for trigger types are:
Level
Level triggering is the default mode. When an input physically transitions from a Normal
to Non-Normal state, an alarm is triggered. However, the alarm persists only while the
input remains in a Non-Normal state. When the input returns to a normal state, the alarm
is cleared.
- 41 -
SmartZone Gateway E24 User Manual
Normal to Non-Normal (Positive Edge)
This type of triggering may be used in situations where a momentary type input (for
example,: a shock sensor or PIR) is used. Since these types of inputs are momentary,
any alarm condition that occurs will persist until manually cleared.
Positive Edge triggering is used when an alarm is required to persist after an input
changes from the Normal state to the Non-Normal state.
Non-Normal to Normal (Negative Edge)
This type of triggering may be used in situations where a momentary type input (for
example, a shock sensor or PIR) is used. Since these types of inputs are momentary,
any alarm condition that occurs will persist until manually cleared.
Negative Edge triggering is used when an alarm is required to persist after an input
changes from the Non-Normal to the Normal state.

The type of connected sensor is specified here. The sensor channels can be set to auto
detect, temperature, humidity, contact, or disabled.
Note: Occasionally, clear traps will be sent to the NMS trap receivers while a sensor is
being connected to a device. This is considered normal behavior, because some voltage
surges may be produced when input sensors are physically connected to the gateway.
In normal operation, the sensors will always be connected to the device and the sensor
voltages will stay within normal expected values
LDAP
E24 LDAP Overview
The E24 implements a Lightweight Directory Access Protocol (LDAP) client.
This allows the E24 unit to authenticate user logins to the Web Management Interface
(WMI) using an LDAP Directory.
If LDAP is used for authentication it is first consulted when a user attempts a login. If the
user is not found or access is denied by LDAP then the credentials are checked against
the E24 internal user list.
Note!Configuration of LDAP is an advanced topic and requires existing knowledge of
LDAP function and setup (or access to personnel who do).
E24 LDAP Structure
In order for a E24 unit to successfully authenticate a user for WMI login it needs to be
‘pointed’ to a specific structure within a directory.
A unit is ‘pointed’ to this structure within a directory by specifying the Unit Base DN on
the Network Setup – LDAP page.
The following Organisational Units will need to be created:
- 43 -
SmartZone Gateway E24 User Manual
l E24 (this can be named anything)
l E24Administrators
l E24Controllers
l E24Viewers
The following Groups will need to be created:
l E24AdminUsers
l E24ControlUsers
l E24ViewUsers
Note: Groups referred to are groups as found in Active Directory schema. However any
implementation which provides a group with a ‘members’ attribute may function.
The following figure depicts the E24 LDAP authentication structure:
- 44 -
SmartZone Gateway E24 User Manual
Once the required LDAP structure has been created the Distinguished Name (DN) of
users should be added to either:
l E24AdminUsers
l E24ControlUsers
l E24ViewUsers
Group Membership and Access Level
Membership of these groups grants the following permissions on E24 units:
- 45 -
SmartZone Gateway E24 User Manual
l E24AdminUsers: Users placed into this group will have Admin privileges on E24
units.
l E24ControlUsers: Users placed into this group will have Controller privileges on
E24 units.
l E24ViewUsers: Users placed into this group will have View privileges on E24
units.
E24 Unit Configuration
For LDAP authentication to function, each E24 unit requires certain configuration values
to be provided.
1. If one LDAP server is to be used select Enabled – Primary.
2. Enter a descriptive name, E.g: AD_Server_1 into Display Name.
3. Enter the complete DN of the top level OU as seen in LDAPLDAP.
4. Enter the DN of where users that are members of E24 access groups can be found
in the Directory. These DNs can be entered into User Base DN 1 and User Base
DN 2.

Temperature Sensor Adapter Installation
Follow the instructions below to install the ZAHTLADT-02 v1.01.01 temperature sensor
adapter module. This adapter allows legacy sensors to provide more accurate temperature readings.
Note: This adapter does not work with the ZETHL-14 temperature sensor.
New Installations
Follow these instructions when you are installing a standard temperature sensor, but the
upgraded sensor input is required.
1. Plug the adapter directly into the back of the gateway, at the sensor port to be used
for temperature.
2. Plug the temperature sensor connector into the adapter.
3. Update the gateway firmware to the latest release.

SmartZone Gateway E24 User Manual
Existing Installations.
Follow these instructions when the sensor is already installed along with the gateway.
1. Unplug the current temperature sensor from the gateway, noting the location where
it resided.
2. Insert the adapter into that location.
3. Plug the sensor into the end of the adapter.
4. Perform these steps for all other temperature sensors to be changed.
5. The gateway firmware must be updated to the latest firmware.

Appendix B: Hysteresis Demystified
When a temperature or humidity limit is reached and the relevant limit has its OFF to ON
Trap enabled, an alarm trap is issued by the SmartZone Gateway unit.
With a zero hysteresis setting, the traps will continue to be generated each time the limit
is reached.
This may be undesirable in a situation where the temperature or humidity level measure
has reduced by only a small amount before rising again and triggering further traps.
The hysteresis function is provided to prevent further alarm traps from being generated
until the measured value has fallen to a satisfactory level.
As shown in image above, the humidity first rises past its upper warning threshold, which
generates an alarm trap.
The humidity then reduces slightly but does not reduce to the hysteresis level, which is
1.5% relative humidity lower than the alarm setting (1.5% relative humidity lower as an
absolute measured value, rather than 1.5% of currently measured value).
Humidity then increases and decreases again. However, on the second decrease of
humidity the level drops below the hysteresis level. The Humidity falling below the hysteresis level re-enables alarm traps for the next alarm event. An upper limit of 25 and a
hysteresis threshold of 1.5 yield a threshold limit of 23.5.
The humidity level again begins to rise and again exceeds the upper limit, however this
time an alarm trap is generated again.

SmartZone Gateway E24 User Manual
The Hysteresis feature acts on the following Temperature and Humidity thresholds:
l Upper Control Limit (UCL)
l Lower Control Limit (LCL)
l Upper Warning Limit (UWL)
l Lower Warning Limit (LWL)
The inverse of the above description is true when applied to Temperature and Humidity
lower control and warning limits.
You can configure the hysteresis threshold by using the menu options.
