8.2. Connecting a Device to the Auxiliary Relay
The ACR/ACT-VoIP Telephone incorporates one on-board relay located on the PCBA, which
enables users to control a low current external relay or device. An external relay could control a
ringer, strobe light, door lock or any other apparatus. The on board relay is protected by a 1
Amp, non-replaceable fuse. Power switched by the relay should not exceed 0.5
Amps @ 30VDC. The PCBA is not designed to handle AC voltages.
See: Figure 6 - Auxiliary
Relay Wiring Diagram
Warning: The relay circuitry contains a non-replaceable 250VAC 1A fuse. If the
fuse blows the board must be returned to Guardian or an approved service
center for repair.
The Telephone relay activation time is selectable through the web interface on the Device
Configuration Page. The relay is controlled by DTMF tones generated from the phone to which
the VoIP phone is connected; no matter which one initiated the call. The DTMF tones are
selectable from the web interface as well.
See: Manual P007402
Setup and Configuration
Note: The three digit code for the auxiliary relay must be sent in conformance with RFC2833
DTMF generation.

17. Guardian Product Return
Guardian products have been quality tested and are in full working order when
shipped from the factory, given the rugged nature of these products shipping is not
expected to damage a unit. In the unlikely event of a malfunction, Guardian follows the
three step procedure below.
Step I - On-Site Correction
The most common source of difficulties with a new product is improper installation in
one of two ways: incorrect wiring connections or connection to an incorrect power
source.
Product wiring needs to be properly connected to the on-site wiring. Correct wiring
instructions are shown in the user manuals included with the product.
VoIP telephones must receive power either from the Ethernet (POE) or from an
external source. If a VoIP telephone fails to function refer to the Question & Answer
section in the Setup and Configuration manual P007402. If the solution is not found in
the Q & A section contact Guardian Tech Support online under Products\VoIP
Technical Support at www.guardiantelecom.com or at 1-800-363 8010.
Step II - Return Materials Authorization (RMA)
When a product has been installed following user manual instructions, and the unit
fails to operate, the user must contact Guardian Telecom to obtain authorization to
return the product. This can be done by done by completing a RMA form online at
www.guardiantelecom.com, or by calling the service telephone number given in this
manual.
After providing information on the product, the owner and the nature of the problem,
Guardian will issue a RMA number, to be shown on documentation returned with the
product.
In addition to the RMA number, shipping documents should include name, address
and telephone number of the owner along with contact information for the person
responsible for the repair and/or the user who identified the malfunction.
(Where a product is being returned for repair from outside of Canada, customs
documentation must show the product’s serial number, date of export [date of
purchase], and a notation that the equipment is: “Canadian goods returning.”)
Step III - Factory Authorized Service
Once received, each product is carefully inspected and tested. If the product is under
warranty, repairs are completed and the product returned to the owner, generally
within five working days of receipt by the factory.
A product that has been subjected to misuse, neglect or accident or is beyond the
warranty period will be evaluated. The service department will provide the owner’s
representative with a repair cost estimate. Once approved, repairs are completed and
the product returned, generally within five working days.
