4. Connectors and Plugs On any unit in the T4 system the two 8 pin connectors are identical The universal cables are all the same with the two ends being identical so it doesn t matter which cable gets attached to which connector It is important however that in hooking units together that they are hooked in a chain To make sure of good electrical contact and waterproof assembly the plug connectors on the universal cables require a three step connecting process when inserted into a panel connector Rotate the plug in the connector while pushing very gently until you feel the plug fit on the connector pins Push the plug into the 8 pin connector as far as it easily goes Next turn the locking ring at least a half turn while continuing to push usually the plug will slide in a small additional amount Finally turn the locking ring clockwise until it comes up snug If an 8 pin system connector is not in use then the dust cover should be closed over it for protection against dirt and water 8 pin connector with dust cover open 8 pin connector with dust cover closed Universal cable with two 8 socket plugs with locking rings The cable ends are identical Locking ring Figure 1 10 8 pin connectors with dust covers and universal cable with 8 socket plugs T4 User s Manual Equipment Description and Setup 12 Power Supply The 24VDC power supply may be used to power the T4 stand alone detector as well as the detec
