Scope, TLINKLT, Telemetry System for One-Way Link

Scope, TLINKLT, Telemetry System for One-Way Link

Comprises of: DL3-05-12V transmitter, RX10LT class 2 receiver & standard aerials. Configured for N/O change-of-state operation unless otherwise specified.

T-Link takes a 5-zone DigiLink transmitter and combines it with a RX10 receiver and two aerials to produce an ‘off the shelf’ one-way radio link between fire or intruder panels. The transmitter has five input zones which can be triggered by volts-free opening or closing contacts or can be configured to accept ’voltage applied’ or ‘voltage removed’.

The system is supplied pre-configured to operate ‘change-of-state’, so a closing contact at the transmitter sends a signal to the receiver to activate the corresponding zone output relay. When the transmitter input is de-activated, the relay is deactivated so the output actually ‘follows’ the input.

A programming kit is available if you need to reconfigure the system. Additional transmitters and receivers can be added when needed.

DL3-05-12V Transmitter
The Scope Digilink MK2 DL1012V and DL512V are 12V dc* powered, programmable Short Range Device (SRD) radio systems which can be used to transmit data to fixed base stations and/or portable receivers.

The unit is supplied with either 5 or 10 inputs, which can be hardware configured to accept either dry contact (no voltage) or voltage (5-18V dc) triggers. Each input is pre-programmed as either N/O (Normally Open), N/C (Normally Closed) or C/S (Change of State). Triggering any of the inputs (zones) will result in pre-programmed data (including up to 80 characters of text message) being transmitted to the selected receiver or group of receivers.

*24V dc input units also available, model codes DL1024V and DL524V.

The unit can be programmed to repeat transmit (1-5 repeat transmissions or until reset) if required. In addition, the trigger filter time can be defined between 100 milliseconds and 25 seconds (period for which the zone must remain in the active state before triggering). One input (IN9) can be configured as a Reset to clear any current transmission cycles. This can also be used as an “Arm/Disarm” facility for the alarm inputs. Various other parameters can be programmed to suit specific user requirements.

RX10LT Class 2 Receiver
Introducing our most versatile receivers to date,the RX10 range is compatible with all our POCSAG transmitters and is completely programmable using PC based configuration software. The 10 zones each have an individual relay output which can be set for latching, momentary or change of state. Data can also be output by the RS232 serial port for logging etc.

Features:

• Scope RX10 fixed telemetry receivers are available as 12V DC or mains powered units which can be used with all Scope UHF POCSAG transmitters
• 10 individual zone relays + common activity relay
• Each zone is individually switchable and can be programmed for latching, momentary or toggle operation
• Front panel status indicators for all zones
• Fully programmable with PC configuration software
• Global Reset by keyswitch or transmitted RIC
• Supervised 'transmitter in service' facility
• RS232 serial port for data logging or repeater functions
• Signal strength indicator (not Lite version)
• 'LT' version is fitted with Class 2 receiver
