IRELESS DETECTORS IN
ABAX
SYSTEM
The wireless detectors send information on violations, tampers, and battery status to the
ACU-100 controller. The detectors may be in either
passive state
(the system is disarmed)
or in
active state
(the system is armed). When in the passive state (battery-saving mode),
the detectors mainly communicate with the controller in time intervals determined by the
R
ESPONSE PERIOD
option.
Then the information on violations and battery status is sent. Only
the detector tamper messages are sent immediately. When in the active state, both the
violations and tampers are sent to the controller right away.
The detectors are switched over from the passive state to the active state, and vice versa,
during the response time, hence performance of this operation is delayed in relation to the
moment of switchover command. This delay, depending on the chosen response frequency,
can be up to 12, 24 or 36 seconds.
The
R
ESPONSE PERIOD
has an effect on the detector energy consumption level. The battery
use by the detector decreases as the frequency of communication between the controller and
the wireless device lowers.
It is advisable in some situations that the detector be always active. For example, the user
wants to be sure that no window is open in the facility at the moment of arming. Switching
over the window protection magnetic detector permanently in active state allows to avoid the
risk that the window will be opened just before arming, but the information about it has not yet
come.
The manner of permanently switching the detector to its active state depends on the
controller working configuration. If the controller operates together with the INTEGRA series
control panels, select the corresponding option for wireless detector. Otherwise, the controller
input for detector control should be programmed as always active.
The batteries ensure operation of the detectors for a period of about 2 years, provided
that they remain in the passive state for some portion of that period, and the R
ESPONSE
PERIOD
is 12 seconds. The lifetime of batteries in the detectors which are permanently
switched to the active state will be reduced. On the other hand, decreasing the
response frequency will extend the battery life. For example, the battery in magnetic
detector for window protection will be sufficient for a period longer than specified, even
if it has been permanently switched over to the active state, if the R
ESPONSE PERIOD
is
set at 36 seconds. The number of possible violations of this detector will be lower than
the number of extra transmissions with the response time of 12 seconds.
Do not leave batteries inside the detectors which are not installed in the system.
If there is no communication with the controller for 10 minutes, the detector will enter
the sampling mode. When in this mode, the detector will check for 38 seconds if it is
being polled by the controller. If it fails to establish communication with the controller, it
will enter the sleep mode for 20 minutes, and then it will check again for 38 seconds if
it is being polled by the controller, etc.
4.8.1 Installation of APD-100 detectors
In order to install the APD-100 passive infrared detector in the system you should:
1. Install battery in the detector.
2. Add the detector to the system (see: A
DDING NEW WIRELESS DEVICES
).
3. Select the location where you want the detector installed, and mount it temporarily in
position.
4. Check the level of signal received by the controller from the detector, and change the
detector installation place, if necessary.
5. Having reached the optimal signal level, install the detector permanently.
