EDWARDS XAL127 Loop Expander Card

The EDWARDS XAL127 Loop Expander Card is a device that can be installed on a control panel to provide an additional device loop. This allows the control panel to support up to 254 device addresses, with a maximum of 127 devices per loop. The card supports both Class B and Class A wiring, and provides three LEDs to indicate loop communication status.

The XAL127 Loop Expander Card is compatible with a wide range of detectors and modules, making it a versatile solution for expanding the capabilities of a control panel.

Operation
The XAL127 loop expander card provides an additional device
loop on the control panel. The card expands the control panel's
device capability to 254 device addresses total, 127 per loop
(any combination of detectors and modules).
Installation
The loop expander card connects to connector J7 on the main
circuit board.
Note: Installation limits are under the jurisdiction of local
authority.
To install the loop expander card:
1. Power down the panel and disconnect the batteries.
2. Locate connector J7 on the main circuit board. It is below
the primary loop card.
3. Connect the card to connector J7 as shown in the
installation diagram. Make sure you properly align the
connector pins and plastic mounting standoffs so that they
lock into place.
4. Connect the field wiring. See “Wiring.”
5. Power up the panel and connect the batteries.

LEDs
There are three LEDs on the card that indicate loop
communication status. Primary is the primary communication
circuit. Secondary is the Class A return communication when
wiring is Class A. Comm is overall loop communication.

Fonctionnement
Le carte de survoltage de boucle XAL127 procure une boucle
supplémentaire au panneau de commande. La carte augmente
la capacité du panneau de commande à 254 adresses, soit
127 par boucle (tout combinaison de détecteurs et de
modules).
Installation
La carte de survoltage de boucle se branche au connecteur J7
sur la carte de circuits imprimés principale.
Remarque : Les limites d’installation relèvent des
autorités locales.
Installation de la carte de survoltage de boucle :
1. Coupez l’alimentation au panneau et débranchez les piles.
2. Localisez le connecteur J7 sur la carte de circuits
imprimés principale. Il est situé sous la carte de boucle
principale.
3. Branchez la carte au connecteur J7 comme indiqué dans
le diagramme d’installation. Assurez-vous de bien aligner
les broches du connecteur et les montants en plastique de
manière à ce qu’ils s'enclenchent correctement.

4. Branchez le filage de canalisation. Voir la section
« Filage ».
5. Rétablissez l’alimentation au panneau et rebranchez les
piles.

Voyants DEL du XAL127
Il y a trois voyants DEL sur la carte qui indiquent l'état de
communication de la boucle. Il y a en premier le circuit de
communication principal. Ensuite, il y a celui qui indique la
communication de retour de la classe A lorsque le filage est de
cette classe. Enfin, il y celui qui indique l’ensemble de la
communication de la boucle.
