WALL - Technical Handbook
5.12.2 Relay outputs
Contact type
This setting determines the default state for the output relays.
• Normally open (default)
• Normally closed
Group activation codes (0=disabled)
This setting is only useful when the unit is used in a D-SERVER System. This enables
the D-SERVER System to broadcast a specific code designated for units configured to
listen for this specific code.
If there is an emergency (e.g. fire) and the D-SERVER wants to tell all doors to open,
then the D-SERVER transmit a group activation when received by the WALL unit, it
will then perform an action included in the transmitted message, e.g. to pulse the
corresponding relay.
Each relay (1 and 2) can be assigned two group activation codes.
Default = 0
Pulse activation time (0.1-6553.5s)
This is the setting for how long a relay will pulse. A group activation or a normal
remote activation message from the D-SERVER can override this setting.
Default = 3 seconds
5.12.3 Technical alarms
Radio test alarm interval (h) (0=off)
This parameter and the next are used to monitor the unit. Every 9 hours
(configurable; 1-255, 0=off) the WALL unit transmits a
Radio test alarm
and expects
to receive an acknowledgement from a monitoring device. If no acknowledge is
received, the unit retries until the “Number of missed ACK” is reached. It then stops
sending the
Radio test alarm
, i.e. the unit is in “Sleep mode”. When in “Sleep
mode”, any other alarm type that is sent by the unit and acknowledged will restart
the “Radio test alarm” interval.
Default = 9
Number of missed ACK before sleep (0=never)
Default = 19
Battery check interval (h) (0=off)
When the unit is powered by batteries only, it can be set to check the status of the
batteries at intervals (1-255 hours, 0=off). When powered by 24 V
DC
this interval is
fixed to 2 hours.
Default = 23
Check battery in 24V mode
To prevent the unit from sending Battery alarm when powered by 24 V
DC
and no
batteries are present, the parameter Check battery in 24 V
DC
mode must be set to
No, function off
.
• Yes, function on
• No, function off (default)
