Product Overview
HDE-VoIP Series Heavy Duty Emergency Telephones
The HDE-VoIP Series telephones are intended for use in public areas where direct assistance or hands-free communication is
required; they provide a hands-free, two-way link to assistance. A call may be initiated from the telephone or from the
monitoring station. The telephone may be programmed to autodial one telephone number. With an optional external signaling
alarm such as a Scream Alert* an HDE-VoIP telephone is an effective tool to alert emergency personnel of an urgent situation.
These telephones also provide the capability of monitoring the status of each unit from a remote location informing personnel
of a malfunction via event configurations. Monitoring equipment is sold separately.
The HDE-11-VoIP, HDE-12-VoIP and HDE-1200-VoIP telephones come with an ADA (American Disability Act) compliant label
(in Braille), making it well suited for University and College campuses, elevators, parking facilities, ATMs, mass transit stations,
amusement parks, senior citizen housing, hospitals and medical centers, or industrial parks.
All models have a relay contact that can energize an alerter, camera or other security device when a call is made from the
telephone. The telephone may be programmed to also energize the alerter when an incoming call is made.
*Scream Alert - a device with a VOX circuit. When the VOX detects a scream the Scream Alert will momentarily close a relay
contact, which will be used to trigger an Emergency phone call.
