3.7.4.1 Strike Wiring, External ADA-10/11, High Security Relay
Use of the internal relays provided on the AIM-1/2SL reader provides a possible security breach as described
above. To prevent the possibility of illegally releasing the door by smashing open the reader and bypassing
the internal relay, external, high security relays may be installed. The ADA-10 and ADA-11 relay module are
designed for this purpose. These relays are not included with the AIM-1/2SL and must be purchased
separately.
The purpose of the ADA-10/11 high security relay is to supervise (protect) the wiring between the reader and
the electric strike. IF THERE IS A POSSIBILITY OF AN INTRUDER ILLEGALLY GAINING ACCESS TO
THESE WIRES, THE ADA-10/11 SHOULD BE USED. If someone illegally gains access the wires between
the reader and the ADA-10/11, it is not possible to cause the door to release. The information passing along
these wires is encoded, digital data, not a simple short or open circuit that is easily compromised.
The wiring between the ADA-10/11 module and the electric strike itself is not protected. To maximize the
increased security of the ADA-10/11 module, the module should be mounted as close to the actual electric
strike as possible, minimizing the length of the unprotected wires.
The ADA-10 module is a potted module with an 8 position connector on the end of a short ribbon cable.
Optional connectors and mounting tools (ATL-10, 490-040) may be purchased from Apollo
The ADA-10 has several jumpers on the top surface that must be cut to configure the operation of the relay.
When cutting the jumpers, it is important to only cut the jumpers at the top of the loop and bend the two
halves apart to prevent them from touching. DO NOT CUT THE JUMPERS FLUSH WITH THE SURFACE
OF THE ADA-10 AS IT MAY BE NECESSARY RECONNECT THEM LATER IF THE WRONG JUMPERS
HAVE BEEN CUT. It may be necessary to wrap the ADA-10 with insulated tape to prevent the ends of the
jumpers from shorting to any external metal objects.
The ADA-11 module is identical in function to the ADA-10 module. It is a smaller, non-potted circuit board
that includes a plastic, “U Channel”, mounting track. Unlike the ADA-10 the power input does not have to be
configured for 12 or 24 volt operation, it automatically works on 12 or 24 volts DC. Also in place of the
jumpers that require cutting on the ADA-10 module, the ADA-11 has DIP switches which are easier to
reconfigure if set incorrectly. Wiring is connected to the ADA-11 using screw terminal blocks instead of the
special connectors utilized on the ADA-10.
BECAUSE THE ADA-11 IS A NON-POTTED MODULE, IF THE RELAY IS TO BE INSTALLED IN A AREA
OF EXTREME ENVIRONMENTAL CONDITIONS, THE ADA-10 IS A BETTER CHOICE. The ADA-11 circuit
is coated with a protective, environmental seal, but it is not as well protected as the potted, ADA-10 module.
