Overview
Trunked Mobile Radio System (TMRS)
This TMR system is shared by nearly all public safety organizations in
Nova Scotia. The network has 86 tower sites and provides coverage across
a large percentage of the provinces’ landmass. All of these tower sites are
connected to a central controller at Bell in Halifax.
The TMR 2 system has new and improved functionality which will
result in enhanced clarity of voice transmissions, system redundancy,
interoperability and additional radio features for some agencies.
This system is fully interoperable, with all agencies having one common
zone of talkgroups. This allows for each user to easily navigate and
communicate with any other user of the system at an incident via their
TMR radio. This includes eight mutual aid talkgroups, three shared
simplex channels and two common talkgroups.
The TMR System (TMRS) uses a digital platform. Public Safety
Organizations will notice much a sharper, crisper voice quality during
radio transmissions in a digital environment. The digital conversion
of a user’s voice reduces external background noise and the digital
technology platform is ideal for reducing environmental noise levels during
transmission, such as emergency scenes or in windy conditions.
When you turn on your radio, it begins to search for the nearest TMRS site.
When the radio connects to a site, the radio will send the identi
fi er number
of your radio to the central controller informing the system that your radio
is now turned on and which talk group your radio is resting on. You can
communicate with any other radio on that same talkgroup province-wide.
This guide will assist the TMR user by explaining speci fi cs about the system
operation, along with lists of agencies sharing the system, radio tones and
alerts, best practices in radio etiquette, potential issues with the system
along with various other helpful hints to make your TMR radio use both
productive and successful.
Please note: This guide will be updated periodically so be sure to review

Field Communications (PSFC) Team.
