1. Introduction
The 8-zone wired extension with supplementary 1.5 A power supply unit
(PSU) enables you to extend the system with 8 wired zones and a
programmable output. The emergency power supply is provided by a 7 Ah
or 17 Ah rechargeable standby battery. You can connect up to four
operating panels to this extension. The extension also permits the
connection of 2 additional loudspeakers for acoustic alarm or service
signals.
2. Installation
Before installing, make sure that the external voltage supply is
disconnected and isolated before making any mains connections.
1. Remove the housing screws of the extension module.
2. Use the housing as a template to locate the fixing screw holes and
drill three holes at these locations (min. 4mm Ø, 4.5 cm long).
3. Pull all cables and cores through the base plate and screw the
housing firmly to the mounting surface. To prevent interference,
pull the 230 V mains cable through a separate opening.
4. Connect all cables and set the jumpers and switches as described
on the next page.
5. Insert the tamper contact in the opening provided.
6. Now connect the standby battery and switch on the 230 V mains
supply.
