to provide an interface point between third party systems (such as
required by telephone entry systems).
Door Monitoring Alarm (MC Input)
Using the MC input, the system can monitor for Door Forced or Door Ajar
alarms.
Door Forced: If the MC input is open circuit without there first having been a
valid card or RTE, then a Door Forced alarm will be generated.
Door Ajar: If the MC input remains open circuit for longer than the allocated
door ajar delay then a Door Ajar alarm will be generated.
To use the door monitoring feature, connect a normally closed alarm circuit
between MC and 0V (this input would usually be derived from an integrated
contact within the locking device).
Note: In addition to the door state monitoring for reader controlled doors, the
System features an additional 3 extended alarm inputs… please see ‘Extended
Alarms’ for more information.
Locks
The XP1M provides the installer with a volt free SPCO relay o/p for
connection of locking devices or third party control equipment (such as vehicle
barriers or powered doors).
For locking devices that draw up to 1.25 Amps, the lock feed can be switched
directly by the relay o/p. For locks that draw above 500mA, the source power
should not be drawn from the 'on-board' XP1M 12v power, but direct from
the PSU fitted in the rear of the enclosure - or from an additional PSU fitted
adjacent to the controller.
An optional ‘Break-Glass’ fire alarm override switch can be fitted in such a way
that it breaks either the positive, or, depending on local codes of practice, both
poles. Under no circumstances should the emergency override be
installed so that it is only switching the negative supply.
The Break Glass device would normally be required if the controlled door
prevented access or egress to a nominated Fire Exit. Please note that some
local authorities will require the use of a Double Pole break glass call
point (configured to disconnect power to both poles of the locking
device).
It is advisable to separately fuse the individual lock feeds using 'in-line' fuses as
shown.
The specific arrangement and connection of the locking device will be
dependent on the type of equipment used. In all cases reference and
