Introduction
1.0SAFECOM Telemetry Communications System
SAFECOM is a long range telemetry communications system for monitoring life safety security alarm panels which are remotely located at a customer site. The SAFECOM system utilizes specially designed telemetry transmitters and receivers to provide a secure and reliable radio communications link between remote alarm panels and a Central Monitoring Station. The information provided to the Central Monitoring Station allows security personnel or local authorities to respond immediately and appropriately to all alarm events detected at the customer site (see the following figure).

1.1SAFECOM Communications Paths
The SC9000 Receiver acts as the nerve center of the SAFECOM Base Station. The SC9000 Receiver uses a personal computer to operate the ST1000 Receiver Software and provide radio communications with remote Radio Communicators via the RF2000 Radio Modem.
A Radio Communicator is a SAFECOM Communications Panel which is located at a customer site; commercial or residential. The SC9000 SAFECOM computer can supervise, monitor, and control up to 2,500 Radio Communicators through
The receipt of each message or poll that is transmitted is validated by the receiving site; SC9000 computer or Radio Communicator. The receiving site will then transmit an acknowledge message in response.
Supervisory polling is performed by the SC9000 computer for each Radio Communicator to verify
The SAFECOM radios can be configured to transmit (TX) and receive (RX) on a single frequency pair directly to the Central Station. When the SAFECOM system is set up for Direct Mode, the SC9000 computer communicates directly with the Radio Communicators in the field. No repeater is used for this type of SAFECOM system (usually found in smaller proprietary systems like those found on a military base, university, or factory/commercial plant).
The SAFECOM radios can also be configured to transmit and receive on a frequency pair to a repeater located on a mountain, tower, or high building in the desired coverage area. When the SAFECOM system is set up for repeater mode, the SC9000 computer communicates with the Radio Communicators through a, UL Listed, SAFECOM SC801 or SC802 Data Repeater, or a commercial grade voice repeater that has been configured with a SAFECOM DP1000PWA Controller Board. The SC801/SC802 or equivalent repeater is normally installed at a Commercial Repeater Site.
