• Model ADB-11
• Audible Base

INTRODUCTION

Model ADB-11
The Model ADB-11Audible Base consists of a standard Series 11 base combined with an audible device. The ADB-11 is an audible base used only with Series 11 conventional detectors (DT-11, PE-11/-11T) and is powered directly from the zone circuit. (Refer to Table 1 for compatible detector model numbers and the related Installation Instructions.) All field wiring terminates at a four position terminal block located on the back of the unit. The audible device sounds when the detector alarms and stops sounding when the system is reset. (Refer to Figure 1, the ADB-11 Audible Base Terminal Blocks, and Figure 2, the ADB-11 Wiring Diagram.) Only one device is guaranteed to activate per zone. The ADB-11 can generate either steady or temporal tone with the insertion of a jumper at the terminal block.

• CAUTION: Do not use looped wire under Terminal 5 of DB-11 base. Use a break in the wire at the terminal to provide supervision of connection.
• TONE: Steady tone = select + and select – are unconnected (without a jumper).
• SELECTION: Temporal = select + and select – are shorted (insert a jumper).
• COMPATIBILITY: Control Panels: CP-2ER, CP-2HR, System 3, MXL/MXL-IQ (CZM-4 only),

APPLICATION NOTE

The ADB-11 is a UL268 listed smoke detector supplementary device which combines detector base and audible device functions. It meets or exceeds the 85 dB at 10 foot audibility requirement for smoke alarms as specified in UL217, Single and Multiple Station Smoke Alarms and NFPA 72 for sleeping areas. When used in conjunction with listed, compatible Siemens equipment, the ADB-11 may be used in lieu of single/multiple station smoke alarms to achieve enhanced, system-level functionality. Typical applications are sleeping rooms in hotels, guest suites, dormitories, day-care, and residential board and care facilities as designated in NFPA 72

• Voltage Rating: 17 – 31 VDC
• Current: Supervisory – 0A
• Alarm – 24mA at 25 VDC
• Constraint: Only one device is guaranteed to activate per zone.

DETECTOR PLACEMENT

The table below lists the detectors that can be used with the ADB-11 Detector Base, along with the appropriate Installation Instructions. Even though no specific spacings are allocated to the detectors used with these bases, use 30 foot center spacing (900 sq ft), as referred to in NFPA Standard 72 National Fire Alarm Code, Chapter 5 and CAN/ULC-S254, as a guide or starting point, if practical, in a detector installation layout. This spacing is based on ideal conditions—smooth ceiling, no air movement, and no physi-cal obstructions. In all installations (except in special circumstances like computer room underfloors), locate the detector on the ceiling, a minimum of 6 inches from a side wall, or on a wall, between 4 and 6 inches from the ceiling. If questions arise regarding detector placement, it is extremely important that the drawings provided or approved by Siemens Industry, Inc. or by its autho-rized distributors be followed! The detector placements shown on these draw-ings were chosen after a careful evaluation of all facets of protecting the area. Environmental factors such as air current, temperature, humidity, air pressure, and the nature of the fire load are carefully considered. Special consideration is given to room or area configuration and the type of ceiling (sloped or flat, smooth or beamed). Siemens Industry, Inc.’s extensive experience in the design of fire detection systems assures optimum detector placement and is reflected in these drawings. Follow sound engineering judgment made by qualified personnel.

DETECTOR WIRING

(USING THE ADB-11 BASE)
Audible base model ADB-11 should be interconnected as shown in the InstallationlWiring Diagrams above and wired to the specific system modules and control panels following the appropriate instructions.

DETECTOR MOUNTING

(USING THE ADB-11 BASE)
The detector base comes from the factory prewired. All signaling and initiating circuits are connected directly to the back of the ADB-11 audible base using the four-position terminal blocks.
Note: The Audible Base Model ADB-11 attaches only to a 4-inch square

Mounting the Detector Base

1. Route all wires out from the outlet box.
2. When the alarm LED viewing is critical, position the LED mark on the base in the intended direction (Refer to Figure 3).
3. Make connections directly to the audible base terminals located on the back of the base. Refer to the related lnstallation/Wiring Diagram above.
4. After all bases are installed, check loop continuity. Refer to System manual for the loop continuity checkout procedure. For ADB-11 loop continuity check, use the jumper furnished in every base (between terminals 1a and 1b) to complete the loop (Refer to Figure 3). An open circuit condition exists until the jumper or detector is installed in the base.
5. If loop continuity is acceptable, remove the jumper at each base and proceed with detector head installation.
