SAGITTARIUS CONVENTIONAL SYSTEM
EXPANDER MODULE
GENERAL DESCRIPTION
The Sagittarius conventional system expander is a module device permitting to add a wireless sub-system to a conventional fire
security installation.
This device is connected directly to the conventional control panel’s zone line and is actually part of it. This device allows wireless
sounders silencing by being controlled by the control panel’s sounder output line.
WHAT TO CHECK BEFORE INSTALLATION
Before installing the conventional system expander module
check these following items:
- This device must be installed following your national and /
or international codes of practice and standards: check them before performing the installation of this device.
- This device is compatible with most of the conventional control panels; check that the control panel is equipped with a power supply
output through which you can, if desired, power the conventional system expander module; check if the panel is provided with a
sounder output; check that control panel’s specifications are suitable; for all this, consult your control panel’s documentation or
consult your control panel’s supplier for more information.
PLACEMENT AND FIXING
The conventional system expander module’s lodgement box is designed with four 20 mm breakable, “knock-out” entry holes (two at
the top and two on the upper side of the rear of the box), allowing sealed, cable gland fitted, cables to be connected to the device.
To place and fix the module perform in sequence the following steps:
- Find a suitable location for the device’s box.
- Prepare the cable openings on the box.
- Securely and adequately fix the device’s box to the wall with adequate screws.
- Fit the cable’s gland (or glands) into the “knocked out” device box’s cable entry.
- Feed the cables into the box, giving them sufficient length for a secure connection.
WIRING CONNECTIONS
The conventional system expander module’s wiring phase of the installation has the following objectives:
- Connect the power supply cables (either from the control panel of from an independent source).
- Connect main and backup power supply monitoring inputs (optional).
- Connect the conventional zone line.
- Connect the control panel’s sounder output (optional).
- Install the end of line (EOL) resistors required as specified in this manual; their values must be chosen according to the control
panel’s specification and literature.
WIRING WARNINGS
Three warnings about wiring:
- Perform any wiring operation with the power supply source and the control panel inactive.
- Electrostatic sensitive device: observe precautions when handling and making connections.
- Connections to the terminals are polarity sensitive, thus, please, check them by referring to the wiring instructions of this manual.
IMPORTANT NOTE
Check and apply the “ZONE ALARM EOL” and the “CHECKING THE POSITIONING OF THE ELECTICAL BRIDGES“ paragraphs
before using the expander module.
WARNINGS AND LIMITATIONS
Our devices use high quality electronic components and plastic materials that are highly resistant to environmental deterioration.
However, after 10 years of continuous operation, it is advisable to replace the devices in order to minimize the risk of reduced perfor-
mance caused by external factors. Ensure that this device is only used with compatible control panels. Detection systems must be
checked, serviced and maintained on a regular basis to confirm correct operation.
Smoke sensors may respond differently to various kinds of smoke particles, thus application advice should be sought for special
risks. Sensors cannot respond correctly if barriers exist between them and the fire location and may be affected by special environ-
mental conditions.
Refer to and follow national codes of practice and other internationally recognized fire engineering standards.
Appropriate risk assessment should be carried out initially to determine correct design criteria and updated periodically.
WARRANTY
All devices are supplied with the benefit of a limited 3 year warranty relating to faulty materials or manufacturing defects, effective
from the production date indicated on each product.
This warranty is invalidated by mechanical or electrical damage caused in the field by incorrect handling or usage.
Product must be returned via your authorized supplier for repair or replacement together with full information on any problem identi-
fied.
Full details on our warranty and product return policy can be obtained upon request.
