LT 1000 Remote Alarm Link
The LT 1000 is a radio based, fully monitored, VHF link system built to fire alarm standards. This enables stand alone alarms (e.g. fire, security, other electronic equipment) to be connected together such that alarm conditions and fault status of each alarm can be brought to a central location without the need for cabling.
The VHF radio link is a fully monitored, radio-based, remote alarm activation system consisting of up to eight transmitter inputs per receiver, built to conform to BS5839-1 and the Loss Prevention Standard 1257.
Outstation (at remote alarm)
- 4 relay inputs per transmitter
- Battery powered (5 years – with 6 months additional back up)
- Monitored radio link
- Integral antenna
- IP65 metal enclosure
Base station (at central point)
- 8 inputs per base station
- Monitored radio link
- 8 relay outputs
- 2 fault outputs
- RS232 Management interface
- Error logging
- 12v dc (240v ac adapter available)
- Battery backup
- IP65 polycarbonate enclosure
Independently tested and certified to:
- ETSI EN 300 220 – Part 3 RF Immunity, Class 1 Equipment
- ETSI EN 301 489 – Part EMC Standard for short range devices, Class 1 equipment
- BS EN 50131-4: 1996 EMC – Product Family Standard Immunity requirements for components of fire, intruder and social alarm systems
Initially designed for use with the Deaf Alerter DA2000 fire alarm system, links can be used with all alarm systems where cabling from remote installations is impractical.
This potential to allow communication to buildings without the need for expensive and disruptive cable runs will radically reduce installation cost for any fire alarm system that requires remote building connectivity.
The LT1000 link receiver has up to eight activation outputs and two fault outputs, all of which are fully monitored volt-free changeover relay contacts. Error logging is enabled, along with a comprehensive LED link status display.
The LT1000 transmitter has up to four fully monitored relay inputs, activations from which are sent simultaneously (many similar products are only capable of sending individual activation signals). Mounted in an IP65 die-cast aluminium enclosure the transmitter is battery powered, with an expected main battery life of five years and back-up battery life of a further six months.
