Configuration
VoIP Telephone Input Contacts
RED ALERT VoIP telephones accept four inputs (see the Specifications section for the input ratings).
Each input’s mode is configurable. Configure inputs for one of the following modes: On, Off, or On/Off.
The inputs can be configured to update a SYSLOG or generate an SNMP trap when active (see Figure 21
on Page 18). Refer to the Logic Settings section of GTC Pub. 42004-548 for programming instructions
for the inputs (see the Reference Documentation section).
VoIP Telephone Output Contacts
Each RED ALERT VoIP telephone contains two voltage-free output contacts (see the Specifications
section for the output ratings). Both outputs are single-pole, single-throw contacts. The mode of each
output is configurable. Configure outputs for one of the following modes: On, Off, Ring, Connect, Hook,
In Use, Ring Out, Registered, or Emergency. The duration of activation, or on/off times, can also be set
in some modes (see Figure 21 on Page 18). Refer to the Logic Settings section of GTC Pub. 42004-548
for programming instructions for the outputs (see the Reference Documentation section).
GAI-Tronics Strobe Connection
Each RED ALERT VoIP hands-free telephone includes two solid state relays. Contact one activates
peripheral equipment such as beacons, video cameras, and alarm generators when the
HELP
push button
is pressed. The relay can remain energized for the duration of the emergency call.
An output is normally used to operate a GAI-Tronics Model 540-001 or 541-001 Strobe (sold separately)
(see Figure 22 on Page 21). Refer to or the appropriate installation instructions included with each strobe
for additional information.
