Fixing The Base Onto A Wall; Alarmsense™ Zone Circuit Wiring - C-TEC AlarmSense CFP702-2 Installation & Maintenance Manual

LPCB APPROVED CFP ALARMSENSE 2/4/8 ZONE FIRE ALARM PANEL

Fixing the base onto a wall

Using the five mounting holes provided (see figure 3 below), fix the base securely onto a vertical wall, ≤2 m
mounting height. The mounting holes are suitable for use with No.8-10, or 4-5mm countersunk screws.
Assess the condition and construction of the wall and use suitable screw fixings for the in-service weight of
the product. Any dust or swarf created during the fixing process must be kept out of the fire alarm panel
and care must be taken not to damage any wiring or components.

AlarmSense zone circuit wiring
™
Depending on the model purchased, two, four or eight AlarmSense™ zone circuit connections are available
on the fire alarm panel. A recommended maximum of 25 devices can be fitted on each circuit which may
include AlarmSense™ detectors, AlarmSense™ manual call points or AlarmSense™ sounders. These can be
mixed in any order. Only AlarmSense™ devices can be used on the zone circuits.
Note: Any AlarmSense™ sounders fitted must be locked to their base or non-removable. If AlarmSense™
sounders are not fitted on a populated zone circuit then this must be programmed into the panel using the
Sounder Status function (see Page 17 for details).
Also, there are limitations on the number of sounders which can be used (please refer to page 8 for
important advice on sounder loading and distribution).

TERMINALS
Connect an end-of-line (EOL) capacitor (provided in the panel 's accessory pack) across the terminals of the
last device on each circuit to allow the wiring to be monitored. Unused zone circuits must also have an EOL
capacitor fitted at the panel terminals.
Note that an open circuit fault on zone circuit wiring will stop some or all of the detectors, manual call
points and sounders operating, and a short circuit will stop all devices operating.
For more specific device wiring information, refer to the instructions provided with the AlarmSense™
devices used.
The wiring for each zone circuit should be connected to the relevant 5mm connector block on the Main
Control PCB and their screens terminated at the panel's base earth distribution post (see page 13 for
detailed second fix connection details).
