When used responsibly, it is possible for the designed intruder alarm system to be set / unset by use of a remote device, assuming the following requirements are adhered to:
- Authorised users at the premises are to be able to cancel the setting procedure;
- Initiation of setting / unsetting should be by user action at the remote device
- Providing no conditions exist that would prevent setting of the intruder alarm system, a timed setting procedure should begin. It will last for a minimum of 30 seconds and a maximum of 60 seconds;
- During the setting procedure, an audible indication will be provided throughout the supervised premises so that any persons present are informed that the setting procedure has started;
- If during the timed setting procedure any intrusion detector is in an active condition, the timed setting procedure will be cancelled. If at the end of the timed setting procedure no conditions exist that prevent setting, the intruder alarm system will set;
- Confirmation of whether the intruder alarm system has set, failed to set, or that an error has occurred, will be provided to the user by the remote device on the basis of information sent to it by the control and indicating equipment (CIE). In respect of this, the CIE will record the information that was sent to the remote device in its event record.
- Event records related to the remote device will include identification of the user or, if this is not possible, the remote device.
When used responsibly, remote devices can be a valuable tool. However, difficulties can occur:
- If using a remote device to remotely set / unset the intruder alarm system, your attention is drawn to the fact that whenever a premises is unattended but its intruder alarm system(s) is (are) not fully set, any related insurance cover might be inoperative. For advice on this matter, it is recommended that you consult your insurer(s).
- A low battery at the remote device or poor intermittent communication could lead to situations where users have initiated setting or unsetting and are unable to verify, at least for a period of time, whether the action was successful or not. Where possible, it is advised that users avoid using remote devices where there are signal strength issues or when the battery is low.
- There is a potential risk of false alarms from the use of remote devices, for example if people are inadvertently still inside the supervised premises when the intruder alarm system is set.
- It is unlikely that an application would incorporate a ‘remember me’ facility to overcome the need to enter an authorisation code each time the application is used. However we would advise you to not implement such a facility for security reasons.
