The G2/G4 supports multiple P25 systems, including Conventional, P25 Trunking, and P25 Conventional. The G3/G5 supports everything the G2/G4 supports in addition to 2 Tone, 5 Tone and MDC 1200 on either of its two bands. They Support:

• Multiple IDs
• 2 Tone, 5 Tone and MDC 1200 (G5 Only)
• Site Trunking
• Full Spectrum Scan
• Linear Simulcast Modulation for Simulcast Applications
• Priority TGIDs
• Multi-select
• 800MHz, 20kHz channel spacing and 4kHz deviation for Direct mode communications

Yes, TGIDs are assigned along with the Control Channels and Site Information (site information is used to further validate that the pager is assigned to that site(s) in situations where Control Channels are reused in the network). The G2/G3/G4/G5 can be pre-programmed with Control Channels and, when first turned on, will scan for the active Control Channel. Once it is on an active Control Channel it stays there until the Bit Error Rate exceeds a predetermined value.

With the G2/G4, sending the page is as simple as sending a 2-tone page. The Dispatcher will select the appropriate icon and when they send the page the system will send out the pre-programmed TGID. The Dispatcher can choose to send an Alerting tone like they do for portable radios or not. Once the TGID is sent the Dispatcher can begin sending the voice message. With the G3/G5, no dispatching changes are required. Agencies can continue receiving their 2-tone calls exactly as before, but gain the ability to also monitor incoming P25 transmissions.

The Administrator will “map” the TGIDs to select Sites or Simulcast Zones. The system then “Forces” the TGID(s) to “Critical Sites”.

Absolutely. The G3/G5 does everything the Minitor does and much, much more. The G3/G5 supports many more RF Channels, with and without PL/DPL, and 2 Tone IDs than the Minitor. With an eight position Selector Knob switch one can configure the G3/G5 for more configurations. And, being IP67 (water and dust proof) and designed for rugged Public Safety environments the G3/G5 ensures reliable operation.

Yes, the receiver covers a fairly broad band that should cover the Control and Traffic Channel frequency range.

Yes! In August of 2018, Comart added Phase II to all devices with Firmware release V1.1. This Phase II release is backwards compatible with Phase I, so all P25 devices are now Phase I and Phase II compatible.

We now support three methods for P25 paging; TGID, Call Alert and QCII over P25. Please contact us to determine which method is best for your application.

They could, or just let the G-Series P25 Voice Pager generate its internal Alerting tone (or wav file).

If the Dispatch Center does not currently dispatch on the P25 system a P25 Control Station will be needed.

The Dispatching Console, 2-way portable or Mobile sends the appropriate TGID to the G-Series P25 Voice Pager. The G2/G3/G5/G5 is monitoring the Control Channel and upon detection of a programmed TGID, it will go to the assigned Traffic Channel for the voice message.

Although this is a good way to initially test the G2/G3/G4/G5, in the final configuration the System will be programmed to “Force TGIDS to Critical Sites” thereby allowing the Dispatcher or a back-up Portable to send messages.

• If you know P25 Service will be available within the next 18 months.
• If I want to continue to use the existing analog 2 tone network, but want to listen to select TGIDs on the P25 System
• If your Mutual Aid relationships have migrated from analog to digital or they have stayed analog while you migrated to digital. If you travel frequently and want to listen of local/regional systems
• If you migrated to digital, but want to monitor analog transmissions (NOAA, etc.)

The pager will decode the TGID and emit an alert tone (user programmable) while it stores the associated message on the assigned Traffic Channel. At the end of the alert tone duration (user programmable) the pager will play the stored voice message from the beginning.

The User determines which TGIDs’ messages are to be stored. All stored messages are time and date stamped and stored in non- volatile memory.  They can easily be retrieved by pressing the playback key button which plays stored messages on a last in/first out basis or by using the pager’s menu to selectively find the time and day the message was received. Message memory is very large and if it nears getting full it will automatically purge the oldest read/unread messages to make room for new incoming messages.

Yes, we have a Message Backup/Manager Utility that allows one to download all stored messages to one’s computer and sort them on several parameters.

Due to high demand, we will be releasing the G3 Dual Band P25 Voice Pager VHF/UHF by Q3 2019!

The G-Series P25 Voice Pagers are software defined radios and we offer periodic Software Update Utilities to our Dealer community to allow them to service their customers as expeditiously as possible. Standard software & updates are complimentary and available for download on our website.

If your pager needs servicing, please contact your Authorized Dealer for instructions. If you are not sure who your Authorized Dealer is, please fill out our Serial Number Search Form.

The G-Series Voice Pagers come with a heavy-duty Lithium Ion 2800mAH battery. The pager includes a micro-USB charging cable with 2-amp power supply.

Battery life greatly depends on the amount of traffic one is monitoring. We have Users getting more than 24 hours and heavy Users getting around 14-16 hours.

We have a Charger Amplifier option that, in addition to having an internal speaker for high noise environments and antenna for RF challenged area, offers a variety of outputs that can be used for external speaker and/or siren/lighting controls.

In addition to the Charger Amplifier, Comart released a standard Desktop Charger option. The Standard Desktop Charger MSRP is $90.00 and the Charger Amplifier MSRP is $150.00.

We have something better. Our pagers support Bluetooth connectivity allowing one to wirelessly connect to a Bluetooth earphone, speaker or one’s vehicle’s speakers.  The Bluetooth capability also ensures we maintain our IP67 (water/dustproof) rating.

One can use the 8-position selector knob switch to manually switch between systems. We are looking at providing an automatic scan feature in a future software update.
