Overview:
The PS1-T3 generates ‘Evacuation’ tones compliant to AS2220 or ISO8201
The PS1-T3 Sounder has a maximum sound pressure level of 98dBA with a sound
distribution pattern shown below. The sound level may be adjusted by a Volume control.
The PS1-T3 Sounder is normally connected to the monitored Bell or Sounder circuit of a
Fire Alarm Panel and is activated when the Sounder circuit voltage polarity is reversed in
the ‘Alarm’ state.
The PS1-T3 Sounder 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.
Specification:
Dimensions: 117 x 74 x 12 H x W x D (mm) - depth above flush-box.
- designed to fit into a standard electrical flush-box fitting.
Colour Options: Red or White.
Sound Level Output: Sound pressure level at 1m (peak ±3dB)
Evacuation, Alert: 98dBA (@24Vdc)
Power Requirements: BELL IN terminal - supplied from the Bell circuit:
Operating Voltage 9.5Vdc to 30Vdc
Quiescent current (Non-Alarm state) 0.4µA (@24Vdc)
Operating current (Alarm state – T3 tone) 9mA average, 25mA peak (@24Vdc)
(Alarm state – AS2220 tone) 14mA average, 28mA peak (@24Vdc)
Controls: Third wire for ‘AS2220 / T3 Evacuation’ tone control.
- 0V on Alert terminal for the ‘AS2220’ tone.
Volume Control: Potentiometer to adjust sound output level – range = 20dB.

Operation:
The panel Bell circuit connects to the PS1-T3 Sounder as shown below.
Bell terminals ‘+’ and ‘-’ connect to the corresponding Sounder ‘+’ and ‘-’ terminals.
If the Bells are not active, the panel monitors the Bell circuit by applying a negative
voltage to the PS1-T3 ‘+’ terminal. The quiescent current drawn by the PS1-T3 under
this condition is less than 0.4µA.
When the panel Bell circuit activates, the panel Bell circuit voltage reverses (applying
positive voltage to the PS1-T3 ‘+’ terminal), sounding the PS1-T3. The ‘T3’ tone is
generated if the ‘Alert’ terminal is open or J3 link not fitted. If the ‘Alert’ terminal of the
PS1-T3 is connected to 0V (negative) or the J3 link is fitted, the ‘AS2220’ tone is
generated instead.
