2.2.6 Connecting manual call points
This fire panel is compatible with all Aritech manual call points. Compatibility with third
party products cannot be guaranteed. Refer to your manual call point manual for more
information.
If a dry contact is connected to a zone it is usually open (NO) and a 100 Ohm 2 W will be
connected in serial. This allows the fire panel to distinguish a detector alarm from a
manual call point alarm.
2.2.7 Class change input connection
This input allows the activation of the sounders from an external push-button. When a
short-circuit is created between these contacts, the sounders and/or bells will activate
until the short-circuit is removed. The push-button must be connected as normally open
(NO).

2.2.8 Auxiliary 24 VDC output connection
Used to power auxiliary devices not included in a zone. It is protected with a fuse and the
maximum current allowed is 250 mA. It is not recommended to use this output to power
elements that have a certain current consumption in their standby mode.

Some manual call points need a 100 Ohm 2W resistor in serial with the
normally open (NO) contact. This resistor avoids that a short-circuit is created
when the call point is activated, and allows the fire panel to identify the origin
of the alarm, differentiating it from the signal given by the detector. Refer to
your manual call point installation guide for further details.
