Guest anguscanplay Posted September 26, 2008 Posted September 26, 2008 might as well get the insults out of the way first - you did allow for the units sleep time ?

All over sesors worked fine first time I didnt no anything about sleep time could you tell me more the sensors were powered up at 1pm and still not working prop by 6pm

james.wilson Posted September 26, 2008 Posted September 26, 2008 yep you need to clear the room for 3-5 mins any activity will extend the sleep timer. You can usually bypass this for testing purposed with a jumper etc in the sensor securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
NitroN Posted September 28, 2008 Posted September 28, 2008 Hi, 1. I don't want to be insulting, but I have often seen wireless PIR's installed upside down... Please check this! 2. a. Unless the wireless detectors are bi-directional, of which very few currently are, the detector does not know if the panel is armed or not. This means that the detector has to transmit every signal to the panel. Picture the wireless PIR in a busy area, ICU, ICU, ICU, ICU, etc. This would kill the PIR's battery life in a short time. b. To extend a wireless PIR's battery life a "sleep period" was introduced. This means that a wireless PIR will transmit the first signal, but will wait for a period of no activity, before it will transmit a second signal. This time differs between different manufacturers. c. Does this reduce the installations effective security? No, as a signal has already been sent to the panel, which, if it is armed, would have created an alarm. d. Normally this is only noticed by an installer walk-testing the system. "Sleep time" normally only applies to wireless PIR's and not other wireless detectors like wireless magnetic contacts, etc. Regards NitroN
