New: View all-in-one DAS Alert Model 1221, now.

The BDA NFPA alarm system will operate with DAS installations that include multiple amplifiers, antennas and power source, and includes circuitry to detect communications faults (open or short circuits) with the DAS equipment.

This Public Safety DAS Remote Annunciator and Monitoring Panel System model 1221B is perfectly suited for SureCall Guardian4 Bi-Directional Signal Amplifier System and many other public safety cell and radio signal booster systems. It provides fire alarm supervision in case any Emergency Radio Responder Coverage (ERRC) system component fails.

Annunciator System Backup Battery.

Shipped with an 9 hr. rechargeable SLA battery that mounts inside the enclosure to provide 24 hours of backup power.

Annunciator Power Supply.

Code Requirements.

The current edition of the NFPA 1221 fire code (shown below) and NFPA-72 (2010, 2013 & 2016) describe the requirements for monitoring the performance of Public Safety in-building two-way Radio Enhancement Systems with a dedicated panel. This panel is required to be located in the fire command center but some jurisdictions require that it be located in the same room as the Radio Enhancement System. These panels are designed to meet all these requirements.

Fault Signalling Relays.

Some DAS components are not configured with appropriate Form-C alarm relays that can interface properly with all Fire Alarm Systems. This unit provides these alarm relays. They can be programmed to mate with any Fire Alarm System with their "normally OFF" or "normally ON" states for any "fail safe" convention that is required by the Fire Alarm System.

Enclosure & Power Requirements.

The enclosure is NEMA-4 rated consistent with the other requirements of the code and a small backup battery (included) inside the panel provides over 24 hours of service if this is needed to supplement loss of primary power. Primary power is provided by an AC socket-mounted 15 VDC power supply (included).

Communication Integrity.

Per code, fault detection cables between the Radio Enhancement System and the panel are monitored to detect open circuits or short circuits to ground. If this condition is detected the panel will trigger a fault alarm to the Fire Alarm System signalling the loss of communications integrity.

Installation.

This panel provides an economical easy-to-install solution to meeting the code requirements and the flexibility to interface with and augment, if required, the fault detection and distributed antenna system alarm signalling capabilities of a large variety of standard components used in these systems. The small size and light-weight enclosure can be wall-mounted into any installation.

WE INSTALL. Please submit installation quote questionnaire for a quote if you require professional installation and assistance with consent and approval process for Public Safety Distributed Antenna System (active DAS) or Public Safety Bi-Directional Amplifier System (passive BDA).

Public Safety DAS Annunciator System Models 1221A and 1221B Comparison.

Both DasAlert Models 1221-A & 1221-B are available in 3 different power versions. Model 1221B is more popular because it is compatible with our SureCall Guardian 3 Public Safety Signal Booster System. Model 1221A's primary use is with older BDA's like the CommScope Node A that does not have NFPA required outdoor donor antenna fault detection. Our 1221-A does this independently of the BDA. It also has the capability to monitor backup power supplies that do not have the required NFPA alarms for the emergency battery and its charger. Here'd detailed overview of differences between the two types of models.

Models 1221A and 1221B Module Descriptions:

Annunciator System with FORM-C relay outputs to main fire alarm system.

Following common in both 1221A & 1221B models.

This is the basic annunciator system that accepts ALARM signaling from external relays contained in the DAS equipment. The system accepts relay signaling indicating the following alarms:

• Loss of AC power.
• Amplifier Problems.
• Antenna Problems.
• DAS Battery Capacity below 30%.
• DAS Battery Charger Fail.
• Communications Faults.
• Summary System Alarm.

Annunciator system provides FORM-C dry relay contacts to provide alarm signaling with any fire alarm installation. The system will operate with DAS installations that include multiple amplifiers, antennas and power source. It includes circuitry to detect communication faults (open or short circuits) with the DAS equipment.

Annunciator System Backup Battery.

Both models are shipped with an 8 Ahr rechargeable SLA battery that mounts inside the enclosure to provide 24 hours of backup power.

Annunciator System Power Supply and Charger.

Both models are shipped with an external 12 VDC power supply and battery charger that can be connected to any 120 VAC power outlet. The battery charger includes indicators that show the health of the panel’s backup battery.

Alternative Donor Antenna Failure Sense Module.

Only in Model 1221-A with any input power source type.

This module provides a means of detecting open circuit, short circuits, disconnected, severed or lose connector problems in the antenna feed from the donor. This circuitry utilizes external bias-T fittings (not included) as shown in Figure 1 below. If your installation has multiple donor antennas, they can be monitored using the connections shown in Figure 2 below.

Model 1221A should be used if your amplifier or other components in your installation do not have the means of detecting donor antenna problems.

Alternative DAS Battery Capacity Sense Module.

Only in Model 1221-A with any input power source type.

If your installation has a backup battery to provide emergency DAS power in the event of an AC power failure, it must be monitored to detect when it has less than 30 % capacity left to power the system when primary power is lost.

Model 1221A should be used if your emergency power unit does not have this capability.

Alternative DAS Battery Charger Failure Sense Module.

Only in Model 1221-A with any input power source type.

If your installation has a backup battery to provide emergency DAS power in the event of an AC power failure, the battery charger must be monitored to detect if it has failed or is degraded.

Model 1221A should be used if your charger unit does not have this capability.
