The emergency call box, MURS Wireless PA (Public Address), conveys voice messages straight from your 2-way mobile radio or base station intercom to the PA speaker that is installed no more than 2 miles in distance. Both the PA receiver and PA speaker can easily be installed and are made for large properties or campuses so everyone can hear the message sent. If hardwired set up is not possible or just too costly and temporary, this emergency call box is ideal for you.
MURS Wireless PA with other MURS Products
MURS Wireless PA is compatible with any of the MURS products that make use of the same frequencies which need no license to operate. When worked together with MURS Commercial Intercom or MURS J-V110 Two-Way Radio, it is possible to program MURS Wireless PA so that only those with the proper code can access the device. With this programming, you can be sure that those who are allowed can only use the system. In addition, you can have a normal conversation using the MURS Wireless PA and your intercom or radio through a dedicated communication channel without it broadcasted.
You can have as many MURS Wireless PA receivers installed throughout the property so you can do paging or zone paging. Either have a code different for each receiver or use the “All Call” code so you can page all zones at the same time. Although with this feature you require the elective DTMF tone decoder set up in your MURS Wireless PA.
Having two loudspeakers installed in one MURS Wireless PA receiver can give you a wider area for coverage. One speaker can reach up to 100 feet away and comes with a cable of 25 feet. This cable can be further extended with the standard RCA phono cables and couplers.
Play Recorded Messages and Weather Broadcasts
Using your two-way radios in the same vicinity as your emergency call box speaker can make your system non-functional. To avoid this, you can have the receiver record the messages received and program it to play back messages over the emergency call box’s speaker once the person using the two-way radio has stopped talking and released the talk button. You only have 20 seconds to record your message.
It is also possible to broadcast emergency weather reports over the speaker to notify everybody. Simply program your MURS Wireless PA to tune in and receive the local NOAA weather from National Weather Service. Also, set your device to have the same frequency as your local weather radio.
MURS Wireless PA
The MURS Wireless PA receiver requires 110VAC power. It also comes equipped with an emergency backup battery that can temporarily power the radio if primary power is interrupted. The rechargeable battery backup is not intended to operate the radio for an extended period of time. A heavy duty external +12 VDC battery can also be used to power the receiver and the receiver can be configured for powered operation to maximize battery life. A solar panel kit can be used to power the MURS Wireless PA receiver without the need for a power supply in locations where AC power is not available.
MURS Wireless PA power on 110V and comes with a backup battery that would power the radio in case of emergencies such as power outage but only for a short time. You can also use the long-lasting external +12 VDC battery to power the emergency call box’s receiver and have it configure to maximize the battery life while in operation. In the event that AC power is not accessible, you can use the solar panel kit to power the device.
To get a wider coverage, you can install the optional external antenna. Have this magnet-mount antenna set up in a place of higher elevation. This antenna comes with a 25 feet cable for maximum coverage.
Usually the emergency call box receiver is not designed to be waterproof. However, there is a fibreglass reinforced polyester enclosure that is weatherproof for the receiver and antenna. This enclosure is for out-of-doors, short term use only.
For heavy traffic places that use MURS radios, the device comes with “2-Tone Decode” capacity. This feature makes it possible for the unit to accept pages coming from “2-Tone Encode” radios. Examples of radios having this feature are MURS J-V110 Two-Way Radio and MURS Commercial Intercom.
Installation and Programming
Once installed, operating the MURS Wireless Public Address radio receiver requires no human contact. The MURS Wireless PA reduces installation costs that would otherwise be incurred by using a wireless PA system.
The MURS Wireless PA receiver does not need any human supervision after it is installed. Having this unit installed is less costly than having the wireless PA system. Once installed, you can use the MURS Channel 1 which is already programmed to the unit with the Interference Eliminator code of 01 just like other MURS Radios. Avoid programming this emergency call box except for enabling other features, although this device is programmable.
