COMMUNICATION PROPERTIES
Property
Description
Heartbeat
When the lock is idle, the heartbeat is a brief communication from the lock to the
PIM400.
The heartbeat allows an idle lock to check for messages from the PIM400. By
default, this occurs every 10 minutes, but can be adjusted in the range of 15
seconds to many hours. Short heartbeat intervals are suggested only if “Time
Zones” accuracy of less than 10 minutes is desired.
The value indicates the time between the heartbeats. Set the value to a shorter time
(lower number) to achieve more frequent communication while the lock is idle. Set the
value to a longer time (higher number) to achieve less frequent communication.
A smaller value will decrease battery life. A larger value will increase battery life.
Immediate
When the lock is used, there is immediate communication to and from the PIM400
regardless of the heartbeat interval.
Wake-Up On
Radio
When enabled, this feature causes the lock to respond within seconds to a
centralized command from the access control panel. When disabled, the lock will
respond only during its heartbeat, which could result in a delay.
Test the function of Wake-Up On Radio, both lock and unlock operations, after all
locks are installed. To test, verify that all locks go to the requested state with no
assistance or intervention. If test fails, toggle Dynamic Channel Switching (DCS) to
its opposite state (off to on, or on to off). Then, re-link all locks and test again.
Cache Mode
When enabled and communicating with the ACP, the lock keeps a local database
of successful access grants.
In the event of communication failure between the AD-400/AD-401 lock and PIM400,
or between the PIM400 and the ACP, access is enabled for facility codes or recent
valid users full card numbers.
Note: When cache mode is confi gured for Smart cards, the default of “full card
numbers” must be used.
The local lock database does not capture audit events.
See the SUS User Guide for more information.
COMMUNICATION FAILURE
When communication fails between the AD-400/AD-401 and the PIM400, the lock will go into
Communication Failure Mode. If the ACP or the PIM400 lose power, the AD-400/AD-401 can lock,
unlock, remain as-is, or allow valid access without communicating to the ACP or the PIM400. This
mode can be confi gured using the SUS. See the SUS User Guide for more information.
Mode
Description
Fail unsecure
unlocked
Lock unlocks and remains unlocked until communication is restored.
Fail secure locked Lock locks and remains locked until communication is restored.
Fail as-is
Lock remains in current state until communication is restored.
In addition, the lock has an internal cache, that can be enabled using the SUS, to allow limited access
while the lock is offl ine. If cache mode is enabled, it is not affected by the communication failure mode
confi guration. See the SUS User Guide for more information.
