7. PART SEVEN - INSTALLATION, POWER, AND PROTECTION
7.1 DO YOU HAVE LIGHTNING PROTECTION ON YOUR TELCO LINES?

yes

no
Zetron can supply a Protection Kit to provide protection from power surges on the telco lines such as
those caused by lightning strikes. The Protection Kit is designed for secondary protection. Primary
protection (such as gas discharge) or Zetron DeadBolt Lighting Surge Arrestors is recommended.
If there is no primary protection on your telco lines, then order one DeadBolt (901-9325) for each analog
phone line as specified in sections 2.5.3 and 3.2.11. If primary protection exists, then order one
protection kit (950-9040) for every 5 Dual Trunk Cards (see sections 2.5.3 and 3.2.11) plus one protection
kit if there are any 4-wire E&M Dual Trunk Cards (see sections 2.5.3.2 and 3.2.11.2) in the system to
protect them against transient voltage spikes.
7.2 CABLE ASSEMBLIES AND PUNCHDOWN BLOCKS
To calculate the number of needed cable assemblies and punchdown blocks, add up the following:
1. One for each TNPP card (see sections 3.1.1.1 and 3.1.2)
2. One for each Multi-port serial card (see section 2.2.3)
3. One for each TAP Outdial card (see section 3.1.3)
4. One for each pair of Radio Station Cards (see section 2.6.1)
5. One for every five Dual Trunk Cards (see sections 2.5.3 and 3.2.11) not already protected by
the Protection Kit (see section 7.1)
6. One if any 4-wire E&M Dual Trunk Cards will be in the system (see sections 2.5.3.2 and
3.2.11.2) and are not already protected by the Protection Kit (see section 7.1)
If you don’t have RJ2 telco cables available, then order the appropriate number of cable assemblies (709-
0004). A minimum of 2 cable assemblies are required. If you don’t have punchdown blocks already
available, then order the appropriate number of punchdown blocks (802-0093-1).
7.3 DO YOU HAVE A BACKUP POWER SUPPLY?

yes


The Zetron Uninterruptible Power Supply (802-9049) is a 400 VA power supply that provides up to 60
minutes of uninterrupted power to a fully-configured Model 2100, or 30 minutes of uninterrupted power to
a fully-configured Model 2200.
