The Modular Alarm System: Customized Large Capacity Network Elements

Alarm Distribution Shelf (ADS)
Design your own alarm system: Our modular systems feature pre-wired shelves, so you can change or add capacities simply by adding cards, with no rewiring required.

The Modular Alarm System allows you to configure large remote telemetry units for the exact capacity and functions you require. Many protocols are supported, including TL1. This system is great for central offices or sites with large quantities of discrete alarms (major, minor, environmental, security, etc.). The Modular Alarm System uses a unique Micro-LAN Channel for data communications between modules.

Modules for the MAS

Modular Alarm Transmitter (MAT)

An alarm collection device that supports 32 ground closure alarm inputs.

Control Processing Module (CPM)

Provides 16 control relay outputs and 8 alarm inputs for remotely activating external devices upon command from T/MonXM.

TL1 Responder Module (64 & 128)

Mediates TL1 Protocol between conventional alarms and TL1 OS or ASCII Terminal.

8-Port TBOS Collector

Collects portions of up to 8 TBOS ports and combines into one TBOS port and also converts TBOS data into one DCPF Port.

TL1 4-Port MUX

Combines up to 4 TL1 ports into one TL1 port.

TBOS-ASCII Converter (TAC) 400-Type

TAC's work in pairs to transport TBOS and ASCII data on a common channel, reducing circuit requirements.

13 Position Fuse Module with Fuse Alarm

A fuse module that is designed to individually protect 13 cards in a 400 type shelf.

Communications Subassemblies for the MAS


202 subassembly

202 Modem Subassembly (1200 baud)

A communications subassembly for MAS modules that supports a 202T modem. Features include standard voice band operation and 1200 Baud data rate.

RS232 Subassembly

RS232 Subassembly

A subassembly for MAS modules that allows a whole shelf to communicate via a single RS232 connection, which in turns drives the Micro-LAN channel of the MAS shelf.

RS422 Subassembly

RS422/RS485 Subassembly

A subassembly for the MAS product line that allows the shelf to communicate via 4 wire RS422 or RS485. This interface accommodates transmission distances up to 4000 ft. Also can drive the Micro-LAN of the MAS shelf.

212 Modem Subassembly (1200 baud dialup)

A subassembly for MAS modules that allows the shelf to function as dialup remote. Features include "AT" command set and TRIP compatibility.

Shelf-Link Subassembly

A subassembly for MAS modules that must reside in each "slave" MAS card to connect it to the "master" MAS card via the Micro-LAN channel.

Shelves for the MAS

List of shelves for the MAS

12 pos wired shelf

400/TYPE 10 19" (12 pos) Wired Shelf

A 12 position 19" shelf that is used to mount MATs, CPMs, Fuse modules and other MAS cards. The shelf is pre-wired for the Micro-LAN channel, power and a fuse module. This unit comes with reversible ears and is suitable for 23" rack mounting.

14 pos wired shelf

400/Type 10 23" (14 pos) Wired Shelf

Like the 12 Position shelf, but wider format accepts 2 more modules.

3 position shelf

400/TYPE 3 position Pre-wired shelf

A 19" 3 position shelf that may be use house MATs, CPMs, and other MAS cards. Comes pre-wired for GROUND and the Micro-LAN communication channels. Reversible ears are also included for mounting in a 23" rack.

Application Specific Shelves

DPS will engineer and assemble for you any application specific shelf assembly. Application specific shelves include backplane wiring and connectorized back panel. Contact sales for a price quotation.

Other Alarm Monitoring Products

DPS offers you a full line of network monitoring choices with the Modular Alarm System and our array of fixed-size remotes, ranging in capacity from 8 to 256 alarm points, along with ASCII, TBOS and analog accessories. Add the T/MonXM & IAM for mediation & polling and the T/GrafX for display functions and you have one stop shopping for complete solutions.
