Introduction

The ADB-3 and ADBI-60 audible bases contain a prewired audible piezo-electric device that produces an 85db signal for localized annunciation. The ADB-3 is designed to be used with conventional Series 3 plug-in detectors. The ADBI-60 is designed for use with addressable analog “X” and intelligent “I” Series plug-in detectors. Typical application includes all areas that normally would require localized audible annunciation such as hotel, motel, apartment, condominiums, and dormitory rooms. The ADB-3 and ADBI- 60 are UL listed and NYMEA approved.

Operation

ADB-3

The ADB-3 is powered by a conventional zone of the system control panel with operation of the piezo electric device being controlled via terminal #6 of the detector base. During the supervision or no alarm condition, circuit ground to the ADB-3 is absent and there is zero current flow. Upon alarm of its detector, circuit ground is provided to the ADB-3 via the base contact of terminal #6 and the audible device is activated producing an 85db audible signal which serves as the local alarm.

The ADB-3 is turned off by the reset of the system control panel. The system guarantees that only one auxiliary or remote device will activate per zone. The ADB-3 operates with an input zone power of 18 VDC- 24 VDC and requires a 4” square, 2½” deep electrical box.

CAUTION: The ADB-3 is not to be used for primary building evacuation, but only as a supplemental audible signal device.

ADBI-60

The Audible Base Model ADBI-60 consists of a standard Cerberus Pyrotronics Series 3 base combined with supportive circuitry for the “X” and “I” Series Detectors and an audible device. All field wiring terminates at two of the four position terminal blocks located on the back of the unit. The ADBI-60 can be used with the MXL, MXL-IQ or IXL Systems. Several different configurations can provide audible signal circuit power to the ADBI-60 at terminals 1 through 4, as shown in diagrams 2, 3, 4 and 5 (See the typical Installation/ Wiring Diagram Section). During the supervision state (no alarms), the polarity of the power to all ADBI-60’s is in reversed normal state, resulting in zero current flow to each base.

When any alarm is reported to the system, the power to all ADBI-60’s reverses polarity, but no audible sounds. The system may then selectively command the ADBI-60, under programmed control, to become audible. All ADBI-60 bases are capable of sounding simultaneous, individually or in any combination depending upon the system Program and control panel. The ADBI-60 is UL 268 listed and achieves the audibility sound output of 85 decibels at ten feet.

CAUTION: The ADBI-60 is not to be used for primary building evacuation, but only as a supplemental audible signal device.

Application Data

The ADB-3 is fully compatible with Series 3 plug-in detectors. When an ADB-3 is used with a compatible detector, no remote relay or lamp device can be used with that same detector. No more than thirty (30) compatible detectors of any type or combination (other than thermals or manual stations) may be used on any one Cerberus Pyrotronics conventional system detector circuit. The ADBI-60 is compatible only with Cerberus Pyrotronics MXL or IXL addressable detectors. No more than sixty (60) “I” Series detectors on MXL or IXL loops may be used on any one addressable initiating circuit.

The smoke detectors used with the ADB-3 and ADBI-60 are subject to the maximum 30 ft. center spacing (900 sq. ft.) as referred to in the National Fire Protection Association Standard 72. This spacing, however, is based on ideal conditions, namely, smooth ceiling, no air movement, and no physical obstructions between the fire source and the detector. This spacing should be used as a guide or starting in detector installation layout. Do not mount detectors in areas close to ventilating or air conditioning outlets. Exposed joists or beamed ceilings may also effect safe spacing limitations for detectors. It is mandatory that NFPA 72 and good engineering judgment be applied regarding detector locations and spacing.

Architect/Engineers Specifications

The audible device that shall be used for localized annunciation shall be contained in a plug-in twist lock detector base that is compatible with Cerberus Pyrotronics “3”, “X” or “I” Series plug-in detectors. The detector base shall contain a prewired piezoelectric device that will produce an audible signal at a minimum of 85 db at 10 feet. The audible device when used with a standard Cerberus Pyrotronics conventional zone fire alarm system shall be the ADB-3. Power shall be provided to the ADB-3 audible base through the zone wires of the fire alarm control panel. The input power provided shall be 18 VDC- 24 VDC. The fire alarm panel shall guarantee that one audible base model ADB-3, or one remote relay model RR-3/3S or one remote lamp model RL-30 or RL-40 will activate per zone.

Once activated the ADB-3 shall be silenced via the reset of the control panel. The audible device, when used with the addressable/ analog, Cerberus Pyrotronics fire alarm MXL or IXL Systems, shall be the ADBI-60. Power shall be provided to the ADBI-60 by the system if the total power requirement is less than 3.0 amps or from a separate auxiliary power supply if the total power requirement exceeds 3.0 amps. 100% of all audible bases shall be capable of sounding simultaneous, individually or in any combination. Once initiated, the audible base shall lock into alarm and must be silenced at the MXL or IXL System control panel or MXL’s optional printer. The audible base, when used with the Cerberus Pyrotronics addressable/analog System MXL or IXL, shall require input power of 28-48 VDC peak fullwave or 20-27 VDC while on battery. The audible bases shall be UL listed.

Constraints

1. The maximum number of ADBI-60’s per a AA-30U, AE-30U, ICP, MMB-1, CES or CSM-4 Bell power loop is 40, with no other devices connected, and with the maximum loop current available.
   • NOTE: The number of ADBI-60’s cannot exceed the maximum current available to the loop. See the IXL Manual, P/N 315-092371, or the MXL Manual, P/N 315- 092036, for the compatibility details of ICon, ALD and audible circuit wiring.
2. Maximum line resistance permitted (both wires), not including the end of the line resistor, is 3 ohms. A minimum of 14 AWG wire must be used.
3. T-tapping of the audible circuit (Diagrams 2, 3, 4, and 5) is not allowed.
   • NOTE: The 24 VDC external power source should not be powering any other devices that could generate noise on the line, such as a Voice Alarm system or devices which are not part of the fire alarm system. If there is any ground detection with the 24 VDC external power, disconnect it.
4. Use the AA-30U for either Class A or Class B wiring; the AE-30U for Class B wiring only (Diagrams 2 and 3).
5. If the ADBI-60 is powered by MXL (Diagrams 4 and 5), the total system power available for indicating appliances is 3A. If more than 3A is required, use the configuration in Diagram 2 or Diagram 3 for auxiliary power.
6. Connect terminal 6 of the PS-35 (Diagrams 2 and 3) to the minus DC side of the MXL main power supply for proper ground fault supervision.
7. Each audible base is marked to indicate its type (ADBI-60 or ADB-3):
   • ADBI-60
   • ADB-3

The boxes are usually marked with a check mark. However, if the audible portion of an ADBI-60 is polarized for reverse polarity detection, the unit is marked with an S. If it is not marked with an S, the audible portion of the unit does not have reverse polarity detection. In either case, each unit must be tested for proper operation.
