RCOMMENDATIONS FOR INSTALLING THE CA824 ALARM SYSTEM
The CA824 Alarm system has been designed and tested according to electromagnetic compatibility
standards.
The following recommendations need to be observed for the proper performance of the alarm system:
1. Make sure the alarm system is securely earthed (neutral).
2. Insulate the low and high voltage cables and use different input box plug-ins.
3. Avoid any connecting conductor loops in the box or their positioning above or below the printed-circuit
board.
4. No additional relays should be placed in the CA824 Alarm system box, as switching these may cause
electromagnetic interference.
4.1. Use only relays with good insulation between plugs and winding.
4.2. The relays connected to open collector outputs must be designed for 12 V DC control voltage and
winding impedance greater than 400
Ω
.
5. A quad conductor cable connects the motherboard with the modules. Using this cable for making any
other connections such as a telephone line, control flashlight signals, sirens or relays
is not recom-
mended.
6. When placing the connecting cables avoid canals or cable forms housing high voltage wirings. This
is especially important where these cables are to be used for supplying power to electric motors,
luminescent lamps or three-phase voltage. Where this is impossible, use sheathed wiring where the
sheath should be earthed only in the alarm system box.
INTRODUCTION
This manual presents the information needed to install CA824 Alarm System modules.
The manual consists of two parts:
- general information about installing system modules
- description of devices and installation details
The manual includes a chart of the structure of menus, which will help detect and access system
configurations.
The following keys are used for programming:
A left arrow for back moves within the menu structure
A right arrow for forward moves within the menu structure
The ENT key for confirmation of any corrections / a transition to the following level of
menu structure
ENT
The CLR key for rejection of any corrections / a transition to prior level menu structure
