PS2 SOUNDER
Pertronic Industries Ltd 1 of 4 0301-PS2 Sounder Issue7 Oct 2002
Overview
The PS2 Sounder is one of a range of sounders manufactured by Pertronic Industries. The PS2
generates the evacuation and alert tones as specified by AS2220. The PS2 can also be used to
generate an alert signal acceptable to NZS4512:1997 (Amendment Two) by giving an
evacuation tone sweep every 15 seconds.
The PS2 has a maximum sound pressure level of 98dBA with a sound distribution pattern shown
below. The sound level may be adjusted by the volume control.
The PS2 is normally connected to the monitored bell or sounder circuit of a fire alarm panel and
to the LED drive output of a conventional or analogue addressable detector. The PS2 will sound
the evacuation tone when the detector is in alarm. If the bell circuit is reversed when the detector
is normal, the evacuation tone or alert tone will be sounded—depending on the state of the
ALERT IN terminal or jumper J3 of the PS2.
The PS2 may also be powered from the analogue addressable loop. In this case, the PS2 will
sound the evacuation tone when the detector is in alarm.
The PS2 may be mounted in a standard single-gang electrical flush-box fitting and is supplied
with a protective plastic cover for installation and building construction use.

Operation
When the PS2 is connected only to the analogue addressable loop (no bells circuit—refer to
figure 1), only the evacuation tone is available. This is sounded when the connected detector or
detectors are in alarm.
When the panel bells or zonal bell driver are connected with the analogue addressable loop
connection (refer to figure 2), both evacuation and alert tones can be generated by the sounder.
This depends on the state of the ALERT IN terminal and on whether the connected detector or
detectors are in alarm. The table shows the effect of the inputs on the tone generated by the
PS2.
Figure 3 shows the configuration for conventional circuit operation. In this case the bells circuit
must be connected.
The ALERT IN (or ALERT OUT) terminal is connected directly or through a relay contact to the
battery negative or 0V to enable the alert tone when the bell circuit is reversed (no detector
alarm). (The ALERT IN and ALERT OUT terminals are physically connected together on the PS2
pcb). These terminals may be connected to other PS2 sounders in order to simultaneously
enable or disable the alert option.
The internal link, J3, may be used to permanently select the alert mode instead of externally
wiring via the terminals. Refer to figure 5 for the location of J3.
Up to 5 detectors may be connected in parallel to the Detector IN terminal to activate the PS2
from different detectors. Similarly, one detector can be wired to up to 5 PS2 sounders to activate
multiple sounders from one detector. These arrangements are shown in the figures.

(insert J4 for

ALERT IN (or J3
inserted) Tone Generated
Monitor mode Normal Open None
Don’t care Active Don’t care Evacuate
Active Normal Open Evacuate
Active Normal 0V (inserted) Alert
Some bell driver circuits can provide a pulsed signal to the PS2 to give an alternative alert signal
using the evacuation tone. The sequence is: 3.75 seconds – evacuation tone (one cycle)
12 seconds – silence
3.75 seconds – evacuation tone
12 seconds – silence, (repeated).
This alternative alert signal complies with NZ4512.
Mixing Sounder Types
PS2 sounders may be connected to a group of PSB sounders so that the detector alarm can be
broadcast in near locations where there are no sounder bases.
Because of electrical loading, there are limitations to the number and type of sounder that may
be connected together. These limits are shown in the table:
Limits to the number of PS2s that may be connected to groups of PSBs
Up to 5 PS2s 4 PS2s 2 PS2s 2 PS2s 2 PS2s
May be connected to a group of 1 PSB 2 PSBs 3 PSBs 4 PSBs 5 PSBs
Note that the PS2s will not sound synchronously with the PSBs.
