General Installation Guidelines
As previously noted, the preferred system configuration is a dedicated telephone line per RED ALERT™
Telephone. This is an actual
requirement
when using TMA in its typical “polling” operation.
Although it is not recommended, RED ALERT™ Telephones can share a telephone line with the
understanding that if two or more telephones are put into use simultaneously, the line current could drop
sufficiently to disconnect the telephone call completely. Additional “line sharing” or “party line”
configuration issues could include sporadic phone operation, difficulties with programming, or premature
disconnection of calls. Special system features (voice mail, call waiting, etc.) could also create problems
if not disabled. Successful shared line operation will depend on the line current, the length of the cable
run, and the condition of the telephone cable.
When sharing a telephone line using TMA, the telephone must be scheduled to “call-in” instead of being
polled by TMA.
Tamper-Resistant Hardware
All of the telephones described in this manual are vandal resistant. The front panel for each telephone
covered in this manual is attached to its enclosure with security screws. A GAI-Tronics Model 233-001
Tamper-Resistant Screwdriver or Torx T-25 security head tip (sold separately) is required for installing
the telephone.
Conduit Installation Details
GAI-Tronics recommends installing telephone lines in conduit to protect against accidental damage and
vandalism. To prevent moisture from entering the enclosure, we strongly recommend the following:
•
Conduit should enter the enclosure from the bottom.
•
If entered from the top, the conduit must be internally sealed to prevent moisture ingress.
•
Sealed fittings should be installed at all cable entry points.
•
Silicone sealant or equivalent should be applied around and inside all conduit entries.
