L747SL Serial Lead

Used to isolate monitoring devices such as PIR1 or door contact.

If you need to protect fire doors, entrance & exit doors or other sensitive areas, the L733 is the ideal solution. The unit is controlled with a key token, which performs all functions when brought near the token detection area on the front panel. The unit also features an integral 20-second exit timer with audible bleep and mode jumper to prevent sensitive or dangerous exit doors being permanently left open.

The FJB2 provides four 'spur' outputs from the network spine with each output incorporating an over current/voltage and reverse polarity protection device. A front panel mounted red/green LED indicates the condition of the internal fuses and continuously monitors the network data signals. Individual fuse failure LEDs are mounted on the reverse of the unit and in the event of cable fault, on one of the outputs, the 'spur' will be isolated without disbaling the entire cable network.

These are normally positioned above doors in a corridor to indicate the status of the call point(s) within each room. The L746s can also be used to monitor several call points for end of corridor indication, or as a 'follow me' light. Each unit is fitted with twin ultra-bright LEDs which mimic the reassurance indicator on the call points. The sounder mimics the LCD display sounding patterns.

If you need an audible alarm to attract attention, but don't need an indication of the call location, the L714 is the simple solution. The sounder is similar in operation to a display unit with a multi level alarm, but has limited zoning facilities. Any assistance or emergency call on the system will over-ride the standard call tone. A built-in relay provides normally open and normally closed 'dry' contacts, which can be used to trigger auxiliary devices.

Slave infra-red receiver which can be linked into other call points.

Installed in conjunction with door monitoring unit or call point and isolation switches. Activates paired call point when door is opened.

The L634 is used to interface an external device to the Intercall system network. The unit features three input triggers: two non-latching and one remote reset and two outputs; Re-assurance LED & open collector which can be used to trigger external equipment for normal or emergency calls. Typical applications include telephone ring detectors, contacts from fire alarm or other control panels or input from remote contacts etc. It may also be used to link two independent Intercall systems together to allo signalling, such that an active alarm on one system triggers a call on the other system and vice versa.

The L622M is the magnetic reset version of the standard call point. It is non-audio and can generate up to 6 independent call levels indicated by the twin colour re-assurance LED. The 'call follower' sounder whih is activated when the call point is in 'staff present' mode, alerts staff to other calls on the system. The jack socket will accept any closing contact input from pear leads, pressure mats, radio triggers and a host of other trigger devices.
