Compliance with IC
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and
maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio
interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically
radiated power (e.i.r.p.) is not more than that necessary for successful communication.
The Manufacturer's rated output power of this equipment is for single carrier operation. For situations when
multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output
signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means
of input power or gain reduction and not by an attenuator at the output of the device.
This equipment complies with IC RSS-102 radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with minimum distance 28 cm between the antenna and your
body,
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une
antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le
but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type
d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas
l'intensité nécessaire à l'établissement d'une communication satisfaisante.
La puissance de sortie nominale indiquée par le fabricant pour cet appareil concerne son fonctionnement avec
porteuse unique. Pour des appareils avec porteuses multiples, on doit réduire la valeur nominale de 3.5 dB,
surtout si le signal de sortie est retransmis et qu'il peut causer du brouillage aux utilisateurs de bandes
adjacentes. Une telle réduction doit porter sur la puissance d'entrée ou sur le gain, et ne doit pas se faire au
moyen d'un atténuateur raccordé à la sortie du dispositif.
Cet appareil est conforme aux limitations de la norme IC RSS-102 concernant l’exposition aux radiations dans un
environnement non contrôlé. Cet appareil doit être installé et utilisé avec une distance minimale de 28 cm entre
l’antenne et le corps de l’utilisateur.

D-MBR 3707-3708 PS NFPA Class A Signal Booster
PRODUCT DESCRIPTION AND USER’S MANUAL
Cobham Wireless –Coverage Date: 17-Jan-16 www.cobham.com/wireless
Doc. No.00060CDUM Rev. 1.1 Page | 1
1 INTRODUCTION
D-MBR 3707-3708 PS NFPA (Digital Multi Band Repeater for Public Safety) is a Class A Digital Multi-
Channel Signal Booster (DCSB). It features an array of up to 12 DSP based, software-controlled,
variable bandwidth filters (up to 75Khz) per band , that are user-programmable across the 700 and
800 MHz bands.
D-MBR 3707-3708 PS NFPA supports all public safety technologies. For each filter, the user can
specify the start and stop frequencies to reduce the installation time of the signal booster and enable
a very wide range of filters selection.
Every parameter of D-MBR 3707-3708 PS NFPA, including filter tuning and selection, can be
controlled via web based management. The patented Cobham Wireless’ digital RF filter enables
simple initial setup for any channel plan and if necessary, allows some basic reconfiguration due to
re-banding.
The SALC -Smart ALC algorithm will reduce the gain to protect the signal booster from oscillation.
When the gain cannot be reduced anymore a shut-down mechanism will be triggered.
The signal booster protects against degradation of the system’s sensitivity and coverage. This is
implemented by the inbuilt AGC per-channel (filter) feature, which permits equalization of the
channel levels for uniform coverage.
This product meets the rigid requirements as defined by the NFPA and International Fire Code
developmental organizations. The amplifier is painted a Fire Life Safety Red, meets NEMA4
compliance for hose down, and provides all Alarming outputs as defined by NFPA 2010, Chapter 24
including system and antenna failures. The signal booster is a DC fed unit.
An external battery charger unit is available as well. The charger is connected to the AC and includes
a circuit to charge external batteries with all the dry contact alarms as defined in the NFPA standard:
AC failure, Charger failure and Low battery.
1.1 Main Features
•Class A - signal booster for SMR and public safety networks
•Supports APCO 25 phase 1 and 2 for public safety networks

1.3 Architecture
To meet the National Fire Protection Association (NFPA) requirements, power to the Signal booster is
provided via an uninterrupted power source. This can either be a UPS or (if a UPS is not available),
an AC Feeder and Battery Charger (purchased separately).
NOTE: The Power Feeder Battery Charger is described in Chapter - 4).
Alarm connections to the Fire Department Control Box are used to monitor the status of the
uninterrupted power source, Signal Booster and DAS system (antennas).
As an alternative to the Fire Department Control Box connections, the D-MBR PS NFPA and UPS or
Charger dry contact alarms can be connected to an Automatic Dialer. The AD-2000 Automatic
Voice/Pager Dialer System is recommended.
If the AC power to the UPS fails, the required power is provided by the battery and the AC Power Fail
alarm is activated.
