Intrinsically Safe Sounder Type DA132
Description
The DA132 Sounder is a lightweight warning Sounder, certified to Ex II 1G Ex ia IIC T4 (Ta –20
o
C to 55°C) with
32 user-selectable tones, and an output level of over 100dB. The Sounder enclosure is also rated to IP65.
The DA132 can be connected to the DA135 to create a single point annunciator, from a single zener barrier or
galvanic isolator.

damage to the sounder
Installation
Mounting
The Sounder should be mounted using the two
available fixing holes in the base. It is recommended
that stainless steel nuts and bolts be used if the
environment is corrosive.
Removing and Replacing the cover
If required the mechanism for locking the Sounder to
the base can be activated by removing the thin section
of plastic shown in Fig 1 with side cutters or a similar
tool. To open a locked head, remove the small black
bung from the hole on the side of the sounder, insert a
thin wire/pointer to depress the clip whilst twisting the
head.
Weatherproof Installation
The O-ring and bung must be fitted and suitable cable
glands used to achieve an IP65 rating. In order to avoid
collection of moisture in the speaker horn, the Sounder
should not be installed with the grille facing directly
upwards.
Wiring
Cable termination should be in accordance with
specifications application of the installation.
The base has three knockouts, two on the side and one
on the base, to accommodate a 20mm conduit or M20
cable glands.
Ensure that only the correct glands are used to maintain
the IP rating of the final assembly
Recommended Cable
0.5 to 2.5mm

with earthed screen and insulating
sheath. Cable parameters are determined by the output
parameters of the interface selected.
Sound Level
The sound level for each of the individual tones are
shown in Table 2. This is assuming the DA132 set at full
volume, driven from a suitable IS interface as shown in
Table 1. A single turn potentiometer is provided to
reduce the volume level by a minimum of 15dB.

Special Conditions for use
The certificate number has an ‘X’ suffix, which indicates that the certificate contains one of more special conditions
for safe use. These are below:
Electrostatic Risk: The equipment shall not be directly installed in any process where its enclosure might be
electro-statically charged by the rapid flow of a nonconductive media. Care must be taken when cleaning, and if
this is necessary it must be done with a damp cloth.

Operating Instructions
Fig 3
Tone Selection
The required tone should be selected by referring to Table 2 below. The first 5 DIL switches of the DIL switch on
the PCB should then be set to the code as shown (1 = ON, 0 = OFF).
Mode Selection
The Sounder has two modes Normal Mode for standard use at 12 or 24VDC using a suitable interface device and
DA135 Mode when used in conjunction with the DA135 IS Beacon as shown below. To select use DIL switch 6,
ON for Normal Mode and OFF for DA135 Mode
Sound Level
The output sound level shown is Table 2 is for a Sounder powered from a suitable barrier or isolator (listed in
Table 1), fed by 24VDC. To reduce the sound output, by up to 15dB turn the potentiometer in the anti-clockwise
direction.
Connection with the DA135
The DA132 can be connected directly to the DA135 Intrinsically Safe Beacon to create a single point annunciator.
To be used in this Mode the Sounder must be in DA135 Mode by putting DIL switch 6 into the OFF position.
