Siemens CERBERUS PYROTRONICS ADB-3 User manual

INTRODUCTION
Model ADB-3
The CERBERUS PYROTRONICSTM Model ADB-3 Audible Base consists of a
standard Series 3 base combined with an audible device. All field wiring
terminates at a four position terminal block located on the back of the unit. The
ADB-3 is used only with Series 3 detectors and is powered directly from the
zone circuit. (Refer to Table 1 for compatible detector model numbers and the
related Installation Instructions.) The audible device sounds when the detector
alarms and stops sounding when the system is reset. (Refer to Figure 1, the
ADB-3 Wiring Diagram.) Only one device is guaranteed to activate per
zone. The ADB-3 is UL 268 listed and meets the UL audibility sound output of
85 decibels at 10 feet.

CAUTION: The ADB-3 must not be used as the primary evacuation
system, but only as a supplemental device.
CAUTION: Do not use looped wire under Terminal 5 of DB-3S base. Use a break
in the wire at the terminal to provide supervision of connection.
Model ADBI-60
The CERBERUS PYROTRONICSTM Model ADBI-60 Audible Base consists
of a standard Series 3 base combined with an audible device. All field wiring
terminates at two four-position terminal blocks located on the back of the unit.
The ADBI-60 is used with System XL3, System IXL (ICON-1), System MXL, or
System MXL-IQ detectors. (Refer to Table 1 for compatible detector model
numbers and the related Installation Instructions.) The ADBI-60 operates as
described below (Refer to Figures 2, 3, 4, 5, 6, 7, and 8).

Several different configurations can provide audible signal circuit power to the
ADBI-60 at terminals 1 through 4, as shown in Figures 2, 3, 4, 5, 6, 7, and 8.
During the supervisory state (no alarms), the polarity of the power to all
ADBI-60s is in a reversed (off-normal) state, resulting in zero current flow to
each base.
Any alarm reported to System XL3 or System MXL/MXL-IQ activates the
TRI-2R or TRI-B6R module and triggers the AA-30U/AE-30U modules (See
Figures 3 and 4). The power to all ADBI-60s reverses polarity for normal
operation, but no audibles sound. The System XL3 or MXL/MXL-IQ may then
selectively command the ADBI-60, under programmed control, to sound via the
circuitry in the addressable detector plugged into each ADBI-60. For IXL
(ICON-1), the CE-S is programmed to follow the system alarm relay (See
Figures 7 and 8). Only those ADBI-60s connected to a detector in alarm will
sound. The ADBI-60 is UL 268 listed and meets the UL audibility sound output
requirement of 85 decibels at 10 feet.

CAUTION: The ADBI-60 is used for primary building evacuation; NFPA 72
requires that the source of audible power be capable of operat-
ing all primary evacuation audibles at the same time.
ELECTRICAL RATINGS AND CONSTRAINTS
Model ADB-3
Voltage Rating: On AC: 28-48 VDC peak, full wave
On battery: 20-27 VDC
Current: Supervisory – 0A
Alarm – 13mA at 25 VDC
Constraint: Only one device is guaranteed to activate per zone.
Model ADBI-60
Voltage Rating: 25 ± 5 VDC
Current: Supervisory – 0A
Alarm – 37mA at 25 VDC
Constraints:
1. The maximum number of ADBI-60s per an AA-30U, AE-30U, SPX-1,
MMB-1/2, SMB-1/2, IXL (ICON-1), 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-60s cannot exceed the maximum current
available to the loop. See the System XL3 Manual, P/N 315-
083206, the IXL Manual, P/N 315-092371, the MXL Manual,
P/N 315-092036, or the MXL-IQ Manual, P/N 315-093624, for
the compatibility details of INX, ALD, and audible circuit wiring.
2. Maximum line resistance permitted (both wires), not including the end
of line resistor, is 3 ohms. A minimum of 14 AWG wire must be used.
3. T-tapping of the audible circuit (Figures 2, 3, 4, 5, and 6) is not
allowed.
4. If the ADBI-60 is powered by System XL3 (Figure 2), the total System
power available for indicating appliances is 5A. If more than 5A is
required, the configuration in Figure 3 or Figure 4 must be used for
auxiliary power.
If an external power source is used on the SPX-1, tie the negative side
of the external power supply to the negative of the PSX 24 VDC power
supply (that is, from terminal 1 or 2 of P9 or P10 on the PSX to terminal
18 of the SPX-1).
Note: The 24 VDC external power source should not be powering any
other devices that could generate noise on the line, such as
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.
5. Use the AA-30U for either Style Z (Class A) or Style Y (Class B)
wiring; the AE-30U for Class B wiring only (Figures 3 and 4).

6. The ADBI-60 is powered by System MXL/MXL-IQ (Figures 5 and 6);
the System power for indicating appliances is 5A. If more than 5A is
required, use the configuration in Figure 3 or Figure 4 for auxiliary
power. See Note above.
7. Connect terminal 6 of the PS-35 (Figures 3 and 4) to the minus DC
side of the System XL3 or MXL/MXL-IQ main power supply for proper
ground fault supervision.
8. The ADBI-60 is powered by System IXL (Figure 7); the System power
on indicating appliances is 3A. If more than 3A is required, use the
configuration in Figure 8.
9. Each audible base is marked as follows to indicate its type (ADBI-60
or ADB-3):

system, refer to the Installation Instructions for that particular
module or contact your authorized Siemens Building Technologies,
Inc. representative.
DETECTOR PLACEMENT
The table at right lists the detectors that can be used with the ADB-3 and
ADBI-60 Detector Bases, 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-S524, 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 Building Technologies, Inc. or
by its authorized distributors be followed! The detector placements shown on
these drawings 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 Building Technologies, Inc.'s
extensive experience in the design of fire detection systems assures optimum
detector placement and is reflected in these drawings. Follow sound engineer-
ing judgment made by qualified personnel.
