below for tone types and related
volumes. The volume can be adjusted
via a single turn potentiometer by 15dB.
Toobtain the second tone, the negative
supply is switched to a third terminal
marked “2nd sound”. 12 or 24VDC ±20%, depending on
model, current 14mA @ 24V,12mA @ 12V 300g
2 Having a deep base and two terminals per
input makes these units convenient for
looping to other circuits or for siting ‘end-
of-line’ resistors. The base has three
knock-outs, two on the side and one on
the base, to accommodate PG13.5/20mm
conduit or cable glands. The units are
polarised and a chain may be fitted with
an ‘end-of-line’ resistor for reverse polarity
testing and to permit line monitoring. Installation Details Please refer to to EC Type ExaminationCertificate and related System Certificate
for full details on suitable interface devices. Recommended Interfaces Zener Barriers: S951 (24V version), S931 (12V version)
