3.1.6 ALARM Slot
The
ALARM
slot (fitted with the alarm connector) allows you to connect devices to the
Switch, such as smoke or movement detectors, sensors, or even other ZyXEL switches which
support the external alarm feature. This feature is in addition to the system alarm, which
detects abnormal temperatures, voltage levels and fan speeds on the Switch.
Your Switch can respond to an external alarm in five ways.
• The
ALM
LED shows an alert.
• The
ALARM
slot can send an external alarm on to another device such as an alarm bell.
• By daisy-chaining the alarm sensor cables from one Switch to another ZyXEL switch
which supports this feature, the external alarm alert (but not the system alarm) is received
on each Switch.
• The Switch can also be configured to send an SNMP trap to the SNMP server. See
for more information on using SNMP.
• The Switch can be configured to create an error log of the alarm. See
for more information on using the system log.
3.1.6.1 Connect a Sensor to the ALARM Slot
This section shows you how to connect up to four sensors to the
ALARM
slot and to let a bell
signal the alarm, as shown in the diagram below.
Figure 19
Connecting Sensors to the
ALARM
connector
Follow these steps to connect an external sensor device to the Switch.
1
Use a connector to connect wires of the correct gauge to the sensor’s power output pins.
See
for the wire specifications. Check the sensor’s
documentation to identify its two power output pins.
2
Connect these two wires to any one of the following pairs of power input pins on the
Switch’s
ALARM
connector - (4,5) (6,7) (8,9) (10,11). The pin numbers run from the
right side of the connector to the left.
2a
Connect each of the sensor’s two power output wires to the
ALARM
connector by
depressing the spring clip corresponding to the pin you are connecting to.
2b
Insert the wire and release the spring clip.
