2.5 Emergency Alarm
This feature helps you to request for aid in emergency. When an Emergency system
is associated to a channel, you can activate emergency feature through the
programmed key.
Hytera DMR system provides four types of emergency alarms:
z Siren Only: The radio emits siren locally.
z Regular: The radio gives visible and audible indications during emergency
state.
z Silent: The radio gives no indication during emergency state.
z Silent with Voice: The radio gives no indication during emergency state, but
will unmute its speaker once it receives a call.
You can select the alarm type on actual requirements. Siren Only indicates the radio
will not transmit the emergency code and emergency call, but only emit siren for
warning. This type is mainly applied in public activities in which you need no other
support. When some support is needed, you can choose Regular, so the radio will
transmit the emergency code or emergency call. Some visible and hearable
indiations will be given. In special occasions, it may be inconvenient to you to make
emergency operation with visible and hearable indications. Silent type will be
preferable then, as during the transmission of silent alarm, the radio will not give any
visible or hearable indications, not affecting the operation of the receiving radios in
the system. A radio with automatic emergency call will receive acknowledge from
other emergency alarm receiving radios. If Silent is selected, the emergency calling
radio will mute the speaker despite of received voices, and you will not know other
users’ responses. If you want to hear the acknowledge from other radios when using
Silent alarm, you can choose Silent with Voice for your radio. In this alarm type, the
radio will only play the received responding voices from other radios without giving
any other visible or hearable indications.
In DMR emergency system are three emergency modes:
z Alarm: The radio only triggers emergency process after you activate
Emergency.
z Alarm with Call: The radio sends emergency alarm and the emergency call
upon Emergency activation.
z Call Only: The radio only transmit emergency call upon Emergency activation.
