The AM921 module is used as an interface
between the MINERVA control panel and the
LaserPLUS and Scanner aspirating detectors.
The module is fitted inside the aspirating
detectors housing at the relay output location and
also takes its power from the detector unit.
The module is addressable and will therefore take
one address on the loop.
Technical Specification
Powered: Loop
Temperature Range: -10°C to 70°C
Operating Humidity: up to 95% RH non-
condensing
Dimensions 921: Fits in VLS/VLP
Product Code (Vol08A-02-D33)

AM921 Addressable Aspirating Interface
The Plant Interface module is an addressable,
multi input/output device that is used to interface
plant equipment to the MINERVA control panel.
Inputs can be used for plant monitoring whilst the
outputs can be driven from the MINERVA control
panel as required.
The module is configured in one of three Modes:
PI521/2 2 inputs and 2 outputs (Takes 4
addresses on the loop; max per loop is 24)
PI521/4 4 inputs and 4 outputs (Takes 8
addresses on the loop; max per loop is 12)
PI521/6 6 inputs and 6 outputs (Takes 12
addresses on the loop; max per loop is 8)
All outputs are rated at 240V 5A. The PI521
requires a separate 24Vd.c. supply to operate.
Technical Specification
Powered: 24Vd.c.
Temperature Range: -10°C to 70°C
Operating Humidity: up to 95% RH non-
condensing
Dimensions: 72H x 245W x 23D mm

PI521 - Plant Interface Module
The SD520 provides two monitored inputs and
one relay output rated at 240V @ 5A. The SD520
is ideally suited to driving smoke damper units
directly from the MINERVA loop. One of the
inputs can optionally be used to monitor the
action of the module relay externally, i.e. at the
smoke damper unit. The SD520 is fitted with a red
LED to indicate locally when the relay is operated.
The SD520 requires a separate 24V d.c. supply to
operate. The module is addressable and will
therefore take one address on the loop.

SD520 - Smoke Damper Interface Module
The LPBD521 module is used to drive the FireRay
2000 beam detector units directly from the
MINERVA loop. A single LPBD521 can be used to
power the analyser unit, the beam receiver unit
and the transmitter unit. Alternatively, two
separate LPBD521's can be used with one to
power the analyser unit and receiver units and the
second to drive the transmitter separately, either
from the same loop or a different loop. Up to 8
LPBD521's can be used per loop.
The module is addressable and will therefore take
one address on the loop.
