  • TypeAlarm System
  • Auto-dials up to four numbers on alarm trigger
  • Stores each number up to 16 digits without power
  • Operates on 11 V to 15 V DC supply
  • Draws only 20 mA at 12 V in standby
  • Works with PSTN DTMF lines, not fibre networks

Alarm System for PSTN Lines

The Jedrek Tiger 911 is an auto telephone dialer designed for PSTN or program-controlled networks using DTMF signalling. It suits installers adding remote alerting to existing alarm panels without fibre-optic telephone connections.

Sustained Operation Behaviour

The unit draws 20 mA at 12 VDC and accepts a 11 to 15 VDC supply range for continuous monitoring. Four stored numbers of up to 16 digits each are retained without power, and the secondary password protects configuration changes during long deployments.

Installation Practicalities

Wiring uses NC, NO or voltage-trigger inputs compatible with standard panel outputs. The seven-segment display and E1 to E4 indicator LEDs confirm number entry and zone status on site. Fibre-optic telephone lines are not supported, so verify the line type before fitting.

Questions about this item

How much power does the Tiger 911 dialer draw when it runs continuously on a 12 V supply?

The unit draws about 20 mA at 12 V in standby, and operates from any DC source between 11 V and 15 V.

What telephone line and wiring must I already have for this dialer to function?

It requires an active PSTN or programme-controlled copper line with DTMF signalling; fibre-optic telephone wiring is not supported.

Can I keep my existing NC/NO sensors and voltage-triggered contacts when adding this dialer?

Yes — the alarm inputs accept normally-closed, normally-open and voltage signals, so legacy sensors connect directly.
