EMS SYSTEM 7000 3. Installation Notes 3.1 Radio Interference. 3.1.1 Door access systems, photocopiers, fax machines, modems, processor controlled security controllers and digital telephone exchanges are a few of the items that on occasion may emit spurious signals. If the spurious emissions correspond to the co-channel or adjacent channel frequencies, they may interfere with the performance despite the careful 7703 receiver design. 3.1.
EMS SYSTEM 7000 4. Functions and Features 4.1 Clear Memory To clear the transmitter serial ident Memory as follows: (a) (b) (c) (d) (e) (f) (g) Detach the front panel from the case leaving all the connecting cables intact. Select RESET mode with the key switch. Depress and hold both the transmitter ADD and DELETE switches adjacent to the processor. Momentarily depresses the MASTER RESET switch adjacent to the transmitter DELETE switch. When the buzzer has bleeped 3 times release the switches.
EMS SYSTEM 7000 Notes: If the Green LED flashes only once, the confirmation signal did not match the Load signal. Repeat from (a). If the Yellow LED does not flash to acknowledge storage, the identity number is already stored in the memory. The POWER LED will turn off during the loading routine. 4.3 Delete Transmitter Identity (a) (b) (c) (d) (e) (f) (g) With either CLEAR or TEST mode selected: Depress and hold the internal transmitter DELETE switch. Select RESET mode using the key switch.
EMS SYSTEM 7000 5.3 Keyswitch 5.3.1 With the keyswitch in the CLEAR position, the green CLEAR and Amber POWER LED's are ON. This signifies the 7703 is active and waiting for signals from the assigned transmitters. If a signal is received at the same time of switching from reset to clear the anti-false alarm function will hold the 7703 in test (with the alarm relay locked) until the signal ceases, when clear mode will automatically be activated. 5.3.
EMS SYSTEM 7000 (g) RADIO INTERFERENCE: KEY IN CLEAR. 30 seconds of an unrecognisable signal will cause the RED RFI LED to turn on. The LED will flash if the signal ceases. Thereafter, the LED will light steadily for any RF interference signal which exceeds one second. Turn the key to reset to clear the display. With the KEY IN TEST, the RFI LED will follow any RF signal.
