Enrolled transmitters and detectors are stored in the AT-304's internal memory and are retained in the AT-304's
memory even in the event of a power failure.
Note:
If the maximum number of 16 wireless devices has been enrolled, the LEARN (OP12) LED will continue to flash
rapidly and no new wireless devices can be enrolled. To enrol new transmitters and / or detectors, all existing
devices must first be erased, and everything must be re-enrolled.
ERASING (ALL) TRANSMITTERS, KEYFOBS AND DETECTORS
If enrolled transmitters, keyfobs or detectors must be deleted, perform the following steps:
1)
Open the casing so that the print is visible.
2)
Set dipswitch 3 on dipswitch 1-8 to ON, the red ERASE (OP11) LED will now flash quickly.
3)
Press switch S1, the ERASE LED stops flashing, lights up steadily after 2 seconds and then extinguishes.
4)
All wireless devices have now been erased from the AT-304's memory.
5)
Return dipswitch 3 on dipswitch 1-8 to the OFF position.
Unique PowerG ID code
A PowerG device is a 2-way wireless 868MHz device that contains a unique ID code. This ID code can only be
enrolled into one AT-304 PowerG receiver. The ID code of the PowerG device is stored in the PowerG receiver
module of the AT-304 and the ID code of the PowerG receiver module is stored in the PowerG device itself. If
enrolling of a PowerG device fails, it may be that another ID code is already present in the PowerG device itself. In
order to enrol the PowerG device, the ID code must first be deleted from the memory in the deivce. For most
PowerG detectors, this is done by pressing and holding
the “Enroll” button on the PowerG
device until the
enrolment LED on the device flashes RED once and then extinguishes. Immediately after the red LED of the enrol
LED flashes, release the “Enroll” button.
The ID code of the PowerG device has now been deleted and the device
can be re-enrolled. To delete the ID code from a keyfob, perform the same procedure with the * key. Also, with a
1-button transmitter you perform the same operation, but now by pushing button itself.
OPERATION OF THE AT-304 RECEIVER
All enrolled Visonic PowerCode and PowerG 868Mhz transmitters, keyfobs and detectors will activate the same
relay output of the AT-304. Depending on the type of transmitter or detector, the relay output will pulse for
approximately 2 seconds or remain toggled.
The AT-304 also has 3 open collector outputs for:
•
Tamper (TAMP)
•
Supervision (SUBV)
•
Low battery (LOWB)
The open collector outputs can be activated by various transmitters, keyfobs and / or detectors. If a wireless device
has a low battery voltage (LOWB), or the tamper contact (TAMP) is opened, the relevant open collector output will
be activated for approximately 3 seconds simultaneously with the relay output when the wireless device is
activated. In this way it is possible to find out which wireless device has an error status.
When a supervision alarm occurs, it is not possible to find out which transmitter, keyfob and / or detector have
activated the open collector output (SUPERV).
