Wir in g Detection Circui ts
Al ldetectioncircuitsmaybewiredas"Endofline"(EOL)or"DoublePole"(DP).Bothmethodscanbe
used on the same system.
D ouble Pole (DP)
The DP method requires the fol lowing:
●
The detector a larm and tamper contacts are connected to the zone and tamper terminals
respectively.
●
The combined alarm and tamper l oop resi stance must be less than 100 Ohms.
●
The ma ximum number of detection devices allowed in a circuit is ten.
●
Normally open devices such as pressure pads and exit terminator buttons are connected
between the zo ne and tamper terminals.
●
If the detect ion circuit is not used links can be fitted across the zone and tamper loop s or
programmed as No t Used.
End Of Line (EOL)
The EOL method requires the following:
● The detector alarm contacts must have a 4K7 shunt resistor fitted.
●
A2K2 End ofLine (EOL)resistor must befitted at the point in the circuitfurthest from thecontrol
panel.
● Loop resistanc e with the EOL resistor shorted must be l ess than 100 Ohms.
● The ma ximum number of detection devices allowed in a circuit is ten.
● Normally open devices such as pressure pads and exit terminator buttons are connected
across outer terminals
●
If the detect ion circuit is not used links can be fitted across the zone and tamper loop s or
programmed as No t Used.
