Pre Power-Up Checks
Once the system is installed, but prior to
powering-up, give the system one final check to
ensure that:
1. The wiring conforms to the requirements
detailed in this manual and that all
interconnections are correct (A to A, B to B
etc.).
2. All system cables are kept clear of mains
supply cables, telephone cables and R.F.
cables. It is recommended that cable ties be
used to keep cables separated.
3. Verify that maximum cable lengths and
resistance's are not exceeded.
4. Mains power supply cables to the system are
connected to an un-switched fused spur.
5. Grommets are used where cables enter metal
housings to ensure that insulation is not
compromised.
ID Cable Checks (TS690ID Only)
Before powering-up the control panel it is
recommended that the following tests are
performed on the ID Loop:
1. Disconnect the two cores of the ID loop from
the control panel [ID LOOP +] and [ID LOOP -]
terminals.
2. Use a DVM to measure the resistance between
the two cores. If the resistance is below 1k
Ohms then there is a short circuit or other wiring
defect on the ID loop. This must be corrected
before going any further. The exact resistance
you measure will depend on the number of ID
devices connected to the ID loop and the
type of DVM that you have. Typical resistance
readings are as follows:
1 device 90K Ohms
10 devices 8.5K Ohms
20 devices 4.5K Ohms
30 devices 2K Ohms
