L746 Addressable Overdoor Light.
The L746 Overdoor light is an optional item usually located above a door or end of corridor to indicate the status of the
call point(s) within. It is fitted with twin ultra-bright LED’s which mimic the re-assurance indicator on the call points.
The unit is fully addressable and requires no separate connection to the call point(s). It is simply set to the address range
of the call points it is required to indicate. There are with two banks of DIL switches, one set to the lowest call point
address and another set to the highest address. As the unit can only show one type of call at a time, calls are priorities as
follows: Attack+Emergency/Assistance/Call. The unit is available with an integral sounder Order code L746S.
Network Terminals: Connect to the Intercall 600 or 700 (2 wire) Network. [+, –] OBSERVE POLARITY
OC Output Terminal: Open collector output active continuously when the alarm is sounding.
Note: Rating 12vDC 100mA. Minimum [ON] resistance = 100 Ohms.
The OC terminal may be used to trigger an external device directly, which will accept this
type of input. Alternatively you may connect this terminal to a RB1 Relay Board which will
provide normally open & normally closed ‘dry’ contacts
.
Jumper JP1: Emergency Only Jumper - When fitted, the unit will only indicate emergency calls.
Jumper JP2: Nurse Present Jumper - When fitted, the unit will not indicate nurse present status.
Light Patterns: Standard/Priority Call - Flashing Red Indication.
Attack / Emergency Call - Rapid Flashing Red Indication.
Staff Present - Continuous Green Indication.
Accepted/Spoken Call - Flashing Green Indication.
Assistance Call - Alternative Red/Green Indication.
Tamper - Slow Alternative Red/Green Indication.
Lower Address : Sets the lowest call point address that the light will respond to.
Upper Address : Sets the Upper call point address that the light will respond to.
The L746 will respond to all call points between the lower & upper addresses with the
highest priority level of call. Overdoor light settings may overlap so that more than light will
respond to several call points. If the unit is required to respond to a single call point
address, set both lower and upper DIL switches to the same address.
Installation: Flush or surface mount in standard ‘single size’ electrical backbox. (See page 21). Connects
to system two core and optional ceiling pull switch and auxiliary devices.
