Multiplexer for extending Single Alarm to Multiple Customers

In recent times many telecom infrastructure companies are offering common passive

infrastructure to more than one cellular operator. This decreases the cost of capital

and maintenance. However, this introduces a problem in case the alarms generated

inside the shelter are to be monitored by more than one cellular company.

To tackle this problem we have developed an Alarm Extender that extends one alarm

to multiple NMS, each one being electrically isolated. Since the outputs are isolated,

even if there is a problem it remains limited to only one operator. Also even if NMS

are incompatible (some work on *5 Volt DC, some work on 3.5 Volt DC) the alarm

system can handle the same.

Please note that a separate power source gives supply to this system and it does not

affect any of the existing systems and can be connected to existing alarms without

any modification.

The system draws negligible current on account. While this saves energy, it also

ensures that the NMS contacts in various equipments are not stressed. The

response time is of the order of milliseconds.

The system is not affected by any short/open of one or more of s or outputs.

Specifications of *6:*4 Model :

1. *6 NO Inputs, *4 Outputs.

2. For each NO Input 4 NO outputs are

available. Each output has NO, NC and C

terminals.

3. (Optionally, we can also take some s

as NC as per user requirements).

4. Each output is electrically isolated.

5. Switchover time of few milliseconds only.

6. LED indication on main panel for the

status of each .

7. Metallic box, powder coated rugged design.

8. Aesthetically pleasing design, with no cables around the panel. A neat cover

covers all the connections.

Specifications of *8:*2 Model :

1. *8 NO Inputs, *2 Outputs.

2. For each NO Input 4 NO outputs are available.

Each output has NO, NC and C terminals.

3. (Optionally, we can also take some s as NC

as per user requirements).

4. Each output is electrically isolated.

5. Switchover time of few milliseconds only.

6. LED indication on main panel for the status of

each .

7. Metallic box, powder coated rugged design.

8. Aesthetically pleasing design, with no cables

around the panel. A neat cover covers all the

connections.

THERE ARE DIFFERENT MODELS BASED ON:

a) NO. of INPUTS

b) INPUT VOLTAGE

c) COST and SIZE

Models can also be customised on request.
