Part Code: A51MULTI
Security Grade 2 Environmental Class 2
Manufactured to BS EN50131-2-6
Description – G2 Flush Contact suitable for all widely available panels. Wired in Single or
Shared Zone configurations.
The A51MULTI is a flush mount contact with integral tamper switch and rectangular plate mounting
arrangement. It is intended to be wired in a fully supervised (EOL) format or 4-wire and benefits from the
option of a second device connected in series.
Operation:- The contact will operate with a gap of approximately 14mm between the magnet and reed.
Installation
Drill a 20mm hole for both the contact and magnet. Rebate an area 28 x 2mm for both fascias.
Wire the contact and select what modules are required, (see wiring instructions below), before inserting the
contact case assembly into the wall/frame.
Ensure the tamper switch has operated.
Fix the contact to the mounting surfaces using the pins provided.
Wiring.
Please refer to the wiring diagram for details.
The product is supplied with two sets of modules. The modules are used to configure the contact for the
panel and allows connection using either resistors or a simple alarm contact.
It is advisable to fit the modules before wiring and fitting the contact.
The modules are colour coded and have an arrow to orientate them as shown in the wiring diagram. The
modules are always used in coloured pairs ie either RED or GREEN.
For example for Honeywell panels you need RED modules and you
install them into the header with the arrows orientated as shown.
The header is a five way header and the XX in the diagram
indicates that the centre pins are NOT used.
For single zone operation you connect to the terminal block as
shown in the single device drawings.
Shared Zone
Two devices can be connected in series to share a single zone.
Refer to the wiring diagram for details.
NOTE the colour and orientation required for each module.
The modules are also placed differently in the header.
NOTE: It is Important that, for any shared zone device, the top module should always occupy the top four
holes in the socket, whereas the lower module only occupies the lower two holes.
