ADT Security Services 50075 1.7 Specifications, 1.8 Telephone Requirements and Warnings

10 Document # 50075 Rev B 3/13/95
DC Power - TB1, Terminals 1 & 2
24 VDC (nominal) filtered, non-resettable and power-limited. Voltage range is 21.2
to 28.2 volts. DC Power TB1 Terminals 1 (+), 2 (-) 40 mA in standby, 75 mA max.
while communicating (for installation in the Unimode 200 enclosure use connector
J10) and 100 mA with the open collector output engaged and communicating.
Data Communications - TB1, Terminals 3 - 7
EIA-485 serial interface, TB1 Terminal 3 = RS+, 4 = RS-, 5= Shield, 6 = Future use,
7 = Future use. Power-limited source must be used. (For installation in the Unimode
200 use connector J10).
Auxiliary Output - TB3, Terminals 2 & 3
TB3-2 = Communicator Failure. Power-limited circuit. An Open Collector type
output, normally high, active low which sinks up to 40 mA. TB3-3 = 21.2 to 28.2
volts, power-limited. Use UL listed relay P/N: MR-101/C or MR-201/C with this
output.
Earth Ground - TB3, Terminal 1
TB3-1 = Earth Ground connection. Connect this terminal to building earth ground
using solid 12 AWG wire to provide lightning protection. This connection is not
required when the UNI•COM is mounted in a Unimode 200 since the metal standoff
used in mounting provides an earth ground connection.
1.8.1 Telephone Circuitry - PH1 & PH2
Ringer Equivalence Number (REN) = 0.6B
AC Impedance 10.0 Mega Ohm
Complies with FCC Part 68
Mates with RJ31X Male Connector
Supervision Threshold: less than 4.0 volts for 2 minutes
The REN is used to determine the quantity of devices which may be connected to the
telephone line. Excessive REN's on the telephone line may result in the devices not
ringing in response to an incoming call. In most, but not all areas, the sum of the
REN's should not exceed five (5.0). To be certain of the number of devices that may
be connected to the line, as determined by the total REN's, contact the telephone
company to determine the maximum REN for the calling area.
1.8.2 Digital Communicator:
Before connecting the UNI•COM to the public switched telephone network, the
installation of two RJ31X jacks is necessary. The following information is provided
if required by the local telephone company :
Manufacturer : Fire·Lite Alarms Inc.
12 Clintonville Rd.
Northford, CT 06472
Product Model Number: UNI•COM
FCC Registration Number: 1W6USA-20723-AL-E
Ringer Equivalence 0.6B
1.8.3 Telephone Company Rights and Warnings:
The telephone company under certain circumstances may temporarily discontinue
services and/or make changes in its facilities, services, equipment or procedures
which may affect the operation of this control panel. However, the telephone
company is required to give advance notice of such changes or interruptions.
