RAD-16LS

Product Information

RAD-16LS

The RAD-16LS is a sixteen zone interior radio box that complies with NFPA 1221. Each zone is end-of-line resistor type with 4.7K Ohms as the standard value. Ground detection is built-in for both sides of each zone connection. The unit consists of 12VDC battery, AC transformer, microprocessor control board, and AM or FM radio transmitter. Built in features include battery charger, watchdog timer, auto restart, clock circuit, alarm/trouble visual and audible indicators, zone bypass, local FORM C trouble relay, AC power fail and low battery detection, fuse blow circuit, and a processor stop circuit should battery voltage drop below 8.5 VDC.

The RAD-16LS is completely compatible with existing 1221 Radio formats. A 24-hour test clock operates on 60 Hz with crystal backup in case of power failure.

Built-in diagnostics pinpoint service problems. Each zone may be individually bypassed during testing. Individual zone alarm and trouble indicators, along with an audible indicator and silencer switcher, are provided. A fuse blow bypass jumper is provided for service use.

Box number and other parameters are easily entered via a built-in programming mode. The programming process is performed completely in circuit, requires no special tools, chips or prom programmers, and does not require any straps, jumpers or soldering. In the test mode the technician may instruct the box to transmit continuously with or without tones.

The tone modulated, one-watt AM transmission is received and decoded by the Mark IV or VI receiver. The 1221 Radio Option (P/N 010001-0098) must be included in the SYSTEM 3505 Prism LX™ order to interface to the RAD-16LS.

Programmable protocols include: Eagle Signal, Digitize, Digitize 99ZN, King Fisher IRAC and Harlow.
