Keyswitch; Tamper - Intek Elite 16D Installation & Programming Manual

Please note the following important points in the end-of-line examples shown on pages 7 & 8;
? Low zones refer to zones 1-8
? High Zones refer to zones 9-16
? You may use either normally closed or normally open detection devices as shown in configurations 8T - Low,
8T - High and 16T however all detectors connected to a zone must be of the same configuration (n/o or n/c)
For example, you may connect a number of normally open smoke detectors in parallel across the 4k7 end-of-line
resistor in the 8T-Low configuration but you cannot connect a normally closed contact in the same zone

In the example above, an activation of the n/c thermal in the parallel branch of the n/o smoke detectors would not
be detected at all. An activation of the thermal in series with the 2k2 end-of-line would produce a "Tamper"
condition rather than the required alarm activation where as an activation of a n/o smoke detector in the parallel
branch would produce an alarm activation.
From this example you can clearly see why you cannot mix n/o and n/c contacts on one zone
KEYSWITCH - This input can be used to control the panel via a keyswitch, digital keypad or similar. This is a multi-
state input which can be end-of-line configured in the same way as the 8 zone inputs. These multiple end-of-line
configurations will produce either full set/unset, monitor mode on/off or set/unset of the A, B or C partitions on an
individual basis.
TAMPER - A 24Hr tamper circuit is available for monitoring tamper status of detectors, junction boxes, cabinets
and satellite sirens etc. This Tamper circuit is programmable with 2 options (P201E5E) either normally closed loop
or 2k2 EOL supervision. The tamper circuit must be terminated with an end-of-line resistor if 2k2 EOL supervision
is selected. The activation events and outputs for this tamper circuit are mapped in the same manner as for
detection zones 1-8.
In addition to the Analogue monitoring inputs, you will find the following system inputs on your Elite 16D control
PCB;
AC - Connect the two low voltage wires (no polarity) from the transformer to the terminals marked AC on the Elite
PCB. The Elite includes a Telepermitted transformer rated at 1.4 amps at 17 volts and incorporates an inbuilt
thermal protection fuse.
