Product Data Sheet
A45E-2
Addressable interface module
Miniature input interface unit
The A45E-2 addressable interface is designed for
installation within the enclosures of equipment
associated with fire detection systems. The unit is
installed directly onto the ZP loop wiring, carries a
system address and enables signals from associated
equipment to be interfaced into the fire alarm
system. Input signals are fully displayed at the
control panel and can be programmed to activate
any system output.
By routing loop wiring and installing interfaces
adjacent to input equipment, system integrity is
increased and the need for long spur wiring between
equipment terminals and the fire alarm interface is
eliminated.
Low profile mouldings
Complying with EN54 Part 18 the A45E-2 can be
installed singly, or used in groups to provide
multiway inputs from equipment such as volt free,
zonal outputs from conventional fire alarm systems
or flow valves from sprinkler installations.
Housed in a low profile, single width moulding the
interface is designed to clip directly onto a standard
DIN rail fixing or be installed in a SMB-DIN100 box
(two unit capacity), or a SMB-DIN200 box (four unit
capacity).
LED indication
A red LED indicator positioned on the front moulding
flashes when the interface has operated, providing
clear identification of the input signal source.
Installed as part of an analogue addressable system,
up to 127 line devices (sensors, callpoints or
interface units) can be connected to each of the
control panel loops. All loop devices incorporate
switch settings enabling them to be assigned a
unique address, which is polled by the panel every
two seconds.
